(CNN)Every morning, Dr. David Fajgenbaum takes three life-saving pills. He wakes up his 21-month-old daughter Amelia to help feed her. He usually grabs some Greek yogurt to eat quickly before sitting down in his home office. Then he spends most of the next 14 hours leading dozens of fellow researchers and volunteers in a systematic review of all the drugs that physicians and researchers have used so far to treat Covid-19. His team has already pored over more than 8,000 papers on how to treat coronavirus patients.

The 35-year-old associate professor at the University of Pennsylvania Perelman School of Medicine leads the school’s Center for Cytokine Storm Treatment & Laboratory. For the last few years, he has dedicated his life to studying Castleman disease, a rare condition that nearly claimed his life. Against epic odds, he found a drug that saved his own life six years ago, by creating a collaborative method for organizing medical research that could be applicable to thousands of human diseases. But after seeing how the same types of flares of immune-signaling cells, called cytokine storms, kill both Castleman and Covid-19 patients alike, his lab has devoted nearly all of its resources to aiding doctors fighting the pandemic.

A global repository for Covid-19 treatment data

Researchers working with his lab have reviewed published data on more than 150 drugs doctors around the world have to treat nearly 50,000 patients diagnosed with Covid-19. They’ve made their analysis public in a database called the Covid-19 Registry of Off-label & New Agents (or CORONA for short).
It’s a central repository of all available data in scientific journals on all the therapies used so far to curb the pandemic. This information can help doctors treat patients and tell researchers how to build clinical trials.The team’s process resembles that of the coordination Fajgenbaum used as a medical student to discover that he could repurpose Sirolimus, an immunosuppressant drug approved for kidney transplant patients, to prevent his body from producing deadly flares of immune-signaling cells called cytokines.The 13 members of Fajgenbaum’s lab recruited dozens of other scientific colleagues to join their coronavirus effort. And what this group is finding has ramifications for scientists globally.
This effort by Dr. Fajgenbaum’s lab and the resultant collaborative effort shows the power and speed at which a coordinated open science effort can achieve goals. Below is the description of the phased efforts planned and completed from the CORONA website.

CORONA (COvid19 Registry of Off-label & New Agents)

Drug Repurposing for COVID-19

Our overarching vision:  A world where data on all treatments that have been used against COVID19 are maintained in a central repository and analyzed so that physicians currently treating COVID19 patients know what treatments are most likely to help their patients and so that clinical trials can be appropriately prioritized.

Phase 1: COMPLETED

Our team reviewed 2500+ papers & extracted data on over 9,000 COVID19 patients. We found 115 repurposed drugs that have been used to treat COVID19 patients and analyzed data on which ones seem most promising for clinical trials. This data is open source and can be used by physicians to treat patients and prioritize drugs for trials. The CDCN will keep this database updated as a resource for this global fight. Repurposed drugs give us the best chance to help COVID19 as quickly as possible! As disease hunters who have identified and repurposed drugs for Castleman disease, we’re applying our ChasingMyCure approach to COVID19.

The following is the Abstract and link to the metastudy.  This study was a systematic review of literature with strict inclusion criteria.  Data was curated from these published studies and a total of 9152 patients were evaluated for treatment regimens for COVID19 complications and clinical response was curated for therapies in these curated studies.  Main insights from this study were as follows:

Key Summary Points

Why carry out this study?
  • Data on drugs that have been used to treat COVID-19 worldwide are currently spread throughout disparate publications.
  • We performed a systematic review of the literature to identify drugs that have been tried in COVID-19 patients and to explore clinically meaningful response time.
What was learned from the study?
  • We identified 115 uniquely referenced treatments administered to COVID-19 patients. Antivirals were the most frequently administered class; combination lopinavir/ritonavir was the most frequently used treatment.
  • This study presents the latest status of off-label and experimental treatments for COVID-19. Studies such as this are important for all diseases, especially those that do not currently have definitive evidence from randomized controlled trials or approved therapies.

Treatments Administered to the First 9152 Reported Cases of COVID-19: A Systematic Review

Abstract

The emergence of SARS-CoV-2/2019 novel coronavirus (COVID-19) has created a global pandemic with no approved treatments or vaccines. Many treatments have already been administered to COVID-19 patients but have not been systematically evaluated. We performed a systematic literature review to identify all treatments reported to be administered to COVID-19 patients and to assess time to clinically meaningful response for treatments with sufficient data. We searched PubMed, BioRxiv, MedRxiv, and ChinaXiv for articles reporting treatments for COVID-19 patients published between 1 December 2019 and 27 March 2020. Data were analyzed descriptively. Of the 2706 articles identified, 155 studies met the inclusion criteria, comprising 9152 patients. The cohort was 45.4% female and 98.3% hospitalized, and mean (SD) age was 44.4 years (SD 21.0). The most frequently administered drug classes were antivirals, antibiotics, and corticosteroids, and of the 115 reported drugs, the most frequently administered was combination lopinavir/ritonavir, which was associated with a time to clinically meaningful response (complete symptom resolution or hospital discharge) of 11.7 (1.09) days. There were insufficient data to compare across treatments. Many treatments have been administered to the first 9152 reported cases of COVID-19. These data serve as the basis for an open-source registry of all reported treatments given to COVID-19 patients at www.CDCN.org/CORONA. Further work is needed to prioritize drugs for investigation in well-controlled clinical trials and treatment protocols.

1085 – Interrogating the RAS interactome identifies EFR3A as a novel enhancer of RAS oncogenesis

Hema Adhikari, Walaa Kattan, John F. Hancock, Christopher M. Counter. Duke University, Durham, NC, University of Texas MD Anderson Cancer Center, Houston, TX

Abstract: Activating mutations in one of the three RAS genes (HRAS, NRAS, and KRAS) are detected in as much as a third of all human cancers. As oncogenic RAS mediates it tumorigenic signaling through protein-protein interactions primarily at the plasma membrane, we sought to document the protein networks engaged by each RAS isoform to identify new vulnerabilities for future therapeutic development. To this end, we determined interactomes of oncogenic HRAS, NRAS, and KRAS by BirA-mediated proximity labeling. This analysis identified roughly ** proteins shared among multiple interactomes, as well as a smaller subset unique to a single RAS oncoprotein. To identify those interactome components promoting RAS oncogenesis, we created and screened sgRNA library targeting the interactomes for genes modifying oncogenic HRAS-, NRAS-, or KRAS-mediated transformation. This analysis identified the protein EFR3A as not only a common component of all three RAS interactomes, but when inactivated, uniformly reduced the growth of cells transformed by any of the three RAS isoforms. EFR3A recruits a complex containing the druggable phosphatidylinositol (Ptdlns) 4 kinase alpha (PI4KA) to the plasma membrane to generate the Ptdlns species PI4P. We show that EFR3A sgRNA reduced multiple RAS effector signaling pathways, suggesting that EFR3A acts at the level of the oncoprotein itself. As lipids play a critical role in the membrane localization of RAS, we tested and found that EFR3A sgRNA reduced not only the occupancy of RAS at the plasma membrane, but also the nanoclustering necessary for signaling. Furthermore, the loss of oncogenic RAS signaling induced by EFR3A sgRNA was rescued by targeting PI4K to the plasma membrane. Taken together, these data support a model whereby EFR3A recruits PI4K to oncogenic RAS to promote plasma membrane localization and nonclustering, and in turn, signaling and transformation. To investigate the therapeutic potential of this new RAS enhancer, we show that EFR3A sgRNA reduced oncogenic KRAS signaling and transformed growth in a panel of pancreatic ductal adenocarcinoma (PDAC) cell lines. Encouraged by these results we are exploring whether genetically inactivating the kinase activity of PI4KA inhibits oncogenic signaling and transformation in PDAC cell lines. If true, pharmacologically targeting PI4K may hold promise as a way to enhance the anti-neoplastic activity of drugs targeting oncogenic RAS or its effectors.

  • different isoforms of ras mutations exist differentially in various tumor types e.g. nras vs kras
  • the C terminal end serve as hotspots of mutations and probably isoform specific functions
  • they determined the interactomes of nras and kras and determined how many candidates are ras specific
  • they overlayed results from proteomic and CRSPR screen; EFR3a was a potential target that stuck out
  • using TCGA patients with higher EFR3a had poorer prognosis
  • EFR3a promotes Ras signaling; and required for RAS driven tumor growth (in RAS addicted tumors?)
  • EGFR3a promotes clustering of oncogenic RAS at plasma membrane

1086 – Downstream kinase signaling is dictated by specific KRAS mutations; Konstantin Budagyan, Jonathan Chernoff. Drexel University College of Medicine, Philadelphia, PA, Fox Chase Cancer Center, Philadelphia, PA @FoxChaseCancer

Abstract: Oncogenic KRAS mutations are common in colorectal cancer (CRC), found in ~50% of tumors, and are associated with poor prognosis and resistance to therapy. There is substantial diversity of KRAS alleles observed in CRC. Importantly, emerging clinical and experimental analysis of relatively common KRAS mutations at amino acids G12, G13, A146, and Q61 suggest that each mutation differently influences the clinical properties of a disease and response to therapy. For example, KRAS G12 mutations confer resistance to EGFR-targeted therapy, while G13D mutations do not. Although there is clinical evidence to suggest biological differences between mutant KRAS alleles, it is not yet known what drives these differences and whether they can be exploited for allele-specific therapy. We hypothesized that different KRAS mutants elicit variable alterations in downstream signaling pathways. To investigate this hypothesis, we created a novel system by which we can model KRAS mutants in isogenic mouse colon epithelial cell lines. To generate the cell lines, we developed an assay using fluorescent co-selection for CRISPR-driven genome editing. This assay involves simultaneous introduction of single-guide RNAs (sgRNAs) to two different endogenous loci resulting in double-editing events. We first introduced Cas9 and blue fluorescent protein (BFP) into mouse colon epithelial cell line containing heterozygous KRAS G12D mutation. We then used sgRNAs targeting BFP and the mutant G12D KRAS allele along with homology-directed repair (HDR) templates for a GFP gene and a KRAS mutant allele of our choice. Cells that successfully undergo HDR are GFP-positive and contain the desired KRAS mutation. Therefore, selection for GFP-positive cells allows us to identify those with phenotypically silent KRAS edits. Ultimately, this method allows us to toggle between different mutant alleles while preserving the wild-type allele, all in an isogenic background. Using this method, we have generated cell lines with endogenous heterozygous KRAS mutations commonly seen in CRC (G12D, G12V, G12C, G12R, G13D). In order to elucidate cellular signaling pathway differences between the KRAS mutants, we screened the mutated cell lines using a small-molecule library of ~160 protein kinase inhibitors. We found that there are mutation-specific differences in drug sensitivity profiles. These observations suggest that KRAS mutants drive specific cellular signaling pathways, and that further exploration of these pathways may prove to be valuable for identification of novel therapeutic opportunities in CRC.

  • Flourescent coselection of KRAS edits by CRSPR screen in a colorectal cancer line; a cell that is competent to undergo HR can undergo combination multiple KRAS
  • target only mutant allele while leaving wild type intact;
  • it was KRAS editing event in APC  +/- mouse cell line
  • this enabled a screen for kinase inhibitors that decreased tumor growth in isogenic cell lines; PKC alpha and beta 1 inhibitors, also CDK4 inhibitors inhibited cell growth
  • questions about heterogeneity in KRAS clones; they looked at off target guides and looked at effects in screens; then they used top two clones that did not have off target;  questions about 3D culture- they have not done that; Question ? dependency on AKT activity? perhaps the G12E has different downstream effectors

1087 – NF1 regulates the RAS-related GTPases, RRAS and RRAS2, independent of RAS activity; Jillian M. Silva, Lizzeth Canche, Frank McCormick. University of California, San Francisco, San Francisco, CA @UCSFMedicine

Abstract: Neurofibromin, which is encoded by the neurofibromatosis type 1 (NF1) gene, is a tumor suppressor that acts as a RAS-GTPase activating protein (RAS-GAP) to stimulate the intrinsic GTPase activity of RAS as well as the closely related RAS subfamily members, RRAS, RRAS2, and MRAS. This results in the conversion of the active GTP-bound form of RAS into the inactive GDP-bound state leading to the downregulation of several RAS downstream effector pathways, most notably MAPK signaling. While the region of NF1 that regulates RAS activity represents only a small fraction of the entire protein, a large extent of the NF1 structural domains and their corresponding mechanistic functions remain uncharacterized despite the fact there is a high frequency of NF1 mutations in several different types of cancer. Thus, we wanted to elucidate the underlying biochemical and signaling functions of NF1 that are unrelated to the regulation of RAS and how loss of these functions contributes to the pathogenesis of cancer. To accomplish this objective, we used CRISPR-Cas9 methods to knockout NF1 in an isogenic “RASless” MEF model system, which is devoid of the major oncogenic RAS isoforms (HRAS, KRAS, and NRAS) and reconstituted with the KRAS4b wild-type or mutant KRASG12C or KRASG12D isoform. Loss of NF1 led to elevated RAS-GTP levels, however, this increase was not as profound as the levels in KRAS-mutated cells or provided a proliferative advantage. Although ablation of NF1 resulted in sustained activation of MAPK signaling, it also unexpectedly, resulted in a robust increase in AKT phosphorylation compared to KRAS-mutated cells. Surprisingly, loss of NF1 in KRAS4b wild-type and KRAS-mutated cells potently suppressed the RAS-related GTPases, RRAS and RRAS2, with modest effects on MRAS, at both the transcript and protein levels. A Clariom™D transcriptome microarray analysis revealed a significant downregulation in the NF-κB target genes, insulin-like growth factor binding protein 2 (IGFBP2), argininosuccinate synthetase 1 (ASS1), and DUSP1, in both the NF1 knockout KRAS4b wild-type and KRAS-mutated cells. Moreover, NF1Null melanoma cells also displayed a potent suppression of RRAS and RRAS2 as well as these NF-κB transcription factors. Since RRAS and RRAS2 both contain the same NF-κB transcription factor binding sites, we hypothesize that IGFBP2, ASS1, and/or DUSP1 may contribute to the NF1-mediated regulation of these RAS-related GTPases. More importantly, this study provides the first evidence of at least one novel RAS-independent function of NF1 to regulate the RAS-related subfamily members, RRAS and RRAS2, in a manner exclusive of its RAS-GTPase activity and this may provide insight into new potential biomarkers and molecular targets for treating patients with mutations in NF1.
  • NF1 and SPRED work together to signal from RTK cKIT through RAS
  • NF1 knockout cells had higher KRAS and had increased cell proliferation
  • NF1 -/-  or SPRED loss had increased ERK phosphorylation and some increase in AKT activity compared to parental cells
  • they used isogenic cell lines devoid of all RAS isoforms and then reconstituted with specific RAS WT or mutants
  • NF1 and SPRED KO both reduce RRAS expression; in an AKT independent mannner
  • NF1 SPRED KO cells have almost no IGFBP2 protein expression and SNAIL so maybe affecting EMT?
  • this effect is independent of its RAS GTPAse activity (noncanonical)

1088 – Elucidating the regulation of delayed-early gene targets of sustained MAPK signaling; Kali J. Dale, Martin McMahon. University of Utah, Salt Lake City, UT, Huntsman Cancer Institute, Salt Lake City, UT

Abstract: RAS and its downstream effector, BRAF, are commonly mutated proto-oncogenes in many types of human cancer. Mutationally activated RAS or BRAF signal through the MEK→ERK MAP kinase (MAPK) pathway to regulate key cancer cell hallmarks such as cell division cycle progression, reduced programmed cell death, and enhanced cell motility. Amongst the list of RAS/RAF-regulated genes are those encoding integrins, alpha-beta heterodimeric transmembrane proteins that regulate cell adhesion to the extracellular matrix. Altered integrin expression has been linked to the acquisition of more aggressive behavior by melanoma, lung, and breast cancer cells leading to diminished survival of cancer patients. We have previously documented the ability of the RAS-activated MAPK pathway to induce the expression of ITGB3 encoding integrin β3 in several different cell types. RAS/RAF-mediated induction of ITGB3 mRNA requires sustained, high-level activation of RAF→MEK→ERK signaling mediated by oncogene activation and is classified as “delayed-early”, in that it is sensitive to the protein synthesis inhibitor cycloheximide. However, to date, the regulatory mechanisms that allow for induced ITGB3 downstream of sustained, high-level activation of MAPK signaling remains obscure. We have identified over 300 DEGs, including those expressing additional cell surface proteins, that display similar regulatory characteristics as ITGB3. We use integrin β3 as a model to test our hypothesis that there is a different mechanism of regulation for delayed-early genes (DEG) compared to the canonical regulation of Immediate-Early genes. There are three regions in the chromatin upstream of the ITGB3 that become more accessible during RAF activation. We are relating the chromatin changes seen during RAF activation to active enhancer histone marks. To elucidate the essential genes of this regulation process, we are employing the use of a genome-wide CRISPR knockout screen. The work presented from this abstract will help elucidate the regulatory properties of oncogenic progression in BRAF mutated cancers that could lead to the identification of biomarkers.

1090 – Regulation of PTEN translation by PI3K signaling maintains pathway homeostasis

Radha Mukherjee, Kiran Gireesan Vanaja, Jacob A. Boyer, Juan Qiu, Xiaoping Chen, Elisa De Stanchina, Sarat Chandarlapaty, Andre Levchenko, Neal Rosen. Memorial Sloan Kettering Cancer Center, New York, NY, Yale University, West Haven, CT, Memorial Sloan Kettering Cancer Center, New York, NY, Memorial Sloan Kettering Cancer Center, New York, NY @sloan_kettering

Abstract: The PI3K pathway is a key regulator of metabolism, cell proliferation and migration and some of its components (e.g. PIK3CA and PTEN) are frequently altered in cancer by genetic events that deregulate its output. However, PI3K signaling is not usually the primary driver of these tumors and inhibitors of components of the pathway have only modest antitumor effects. We now show that both physiologic and oncogenic activation of the PI3K signaling by growth factors and an activating hotspot PIK3CA mutation respectively, cause an increase in the expression of the lipid phosphatase PTEN, thus limiting the duration of the signal and the output of the pathway in tumors. Pharmacologic and physiologic inhibition of the pathway by HER2/PI3K/AKT/mTOR inhibitors and nutrient starvation respectively reduce PTEN, thus buffering the effects of inhibition and contributing to the rebound in pathway activity that occurs in tumors. This regulation is found to be a feature of multiple types of cancer, non-cancer cell line and PDX models thereby highlighting its role as a key conserved feedback loop within the PI3K signaling network, both in vitro and in vivo. Regulation of expression is due to mTOR/4EBP1 dependent control of PTEN translation and is lost when 4EBP1 is knocked out. Translational regulation of PTEN is therefore a major homeostatic regulator of physiologic PI3K signaling and plays a role in reducing the output of oncogenic mutants that deregulate the pathway and the antitumor activity of PI3K pathway inhibitors.

  • mTOR can be a potent regulator of PTEN and therefore a major issue when developing PI3K inhibitors

  • most sensitive cell lines to inhibitor carry KRAS mutation; NRAS or BRAF mutations are not sensititve
  • KRAS mutation defines sensitivity so they created KRAS mut isogenic cell lines
  • found best to co inhibit SOS and MEK as observed plasticity with only SOS
  • dual combination in lung NSCLC pancreatic showed enhanced efficacy compared to monotherapy
  • SOS1 inhibition plus irinotecan enhances DNA double strand breaks; no increased DNA damage in normal stroma but preferentially in tumor cells
  • these SOS1 had broad activity against KRAS mutant models;
  • phase 1 started in 2019;

Funding Research by Lottery?: How Lucky Do You Feel After Submitting a Grant

Reporter: Stephen J. Williams, Ph.D.

A recent article in Nature: “Science Funders Gamble on Grant Lotteries” discusses an odd twist to the anxiety most researchers feel after submitting grants to an agency.  Now, along with the hours of fretting over details and verbiage in a grant application, it appears that not only great science, but the luck of the draw may be necessary to get your work funded.  The article, by David Adam, discusses the funding strategy of the Health Research Council of New Zealand, which since 2015, has implemented a strategy of awarding grants through random selection.  Although limited in scope and size (mainly these grants are on very highly speculative and potentially transformative research and awards are usually less that $150,000 NZD) was meant to promote the applicants in submitting more risky ideas that are usually submitted in traditional peer reviewed grants.

Random chance will create more openness to ideas that are not in the mainstream

–  Margit Osterloh, economist at University of Zurich

Margit also mentions that many mid-ranking applications which are never funded could benefit from such a lottery system.

The Swiss National Science Foundation (SSFS) is also experimenting with this idea of random selection.  The Health Research Council states the process in not entirely random.  A computer selects the projects at random based on a random number generator.  A panel then decides if they are a reasonably good and well written application.

Some researchers have felt this random process could help eliminate much bias that can be baked into the traditional peer review process.  However there are many who feel the current process of peer review panels are a necessary and rigorous step in the granting process, analyzing applications which would most likely have the best chances to succeed based on the rigor of the proposed science.

However Osterloh feels that the lottery idea produces a humbling effect. As Margit said

If you know you have got a grant or a publication which is selected partly randomly, then you will know very well you are not the king of the Universe

Humility in science: a refreshing idea.  However the lottery idea will not mean that scientists need not prepare a careful and well written application.  Applications that are ranked very low would not be in the lottery.  However, if one feels lucky, maybe the obscene hours of worrying about each sentence written, or that figures for preliminary data should be altered at the 11th hour before submission might be a thing of the past.

Of course if you are a lucky person.

Science and technology bring tremendous value to society in years of life and quality of life, yet the public often perceives science as difficult, irrelevant or even threatening. Moreover, the inspirational and moving stories of scientists and innovators working around the world are often hidden or misrepresented in popular culture. Whose responsibility is it to communicate science and engage the public in supporting the scientific enterprise? Can everyone be a Champion of Science and what are the solutions to enlist and engage more champions of science across generations and geographies? How do we work together to enhance transparency, accessibility and relevance of science for everyone, everywhere? Can science become more inclusive and engage hearts and not only minds?

Join this exciting session as Johnson & Johnson announces the winners of the Champions of Science – BioGENEius Storytelling Challenge, and brings together other key stakeholders in a discussion about the importance of engaging the public to fall in love in science all over again.

Sponsored by: Johnson & Johnson Innovation

Seema: We need to solve the problem of the lack of trust in scientists.  Some of JNJ winners of their acheivement program went on to become Nobel Laureates.   Arthur Horwich and Hans Ullrich won the Jannsen Award for discovering compounds that could refold proteins, including protein chaperones.  Many diseases occur because of protein misfolding like neuro-degenerative diseases.
Seema:  Great science going on in Africa.  JNJ wanted to showcase the great science in Africa. they awarded four individuals with storytelling award (Emily).
Dr. Horwich: got interested in science early on.  Worked on N terminal mitochondrial signal peptides.  also then got interested in how proteins fold and unfold and refold since the 1950s.  He had changed the thinking of how proteins are processed within cells and over many years he had worked on this.
Emily Wang:  Parents and schoolteachers prodded her curiosity in biology. The impact of day to day work of scientists is arduous but the little things can lead to advances that may help people.  If passionate and have a great mentor then can get a foot in the door.  Worked at Stanford in the lab.
Dr. Mukherjee: He likes to cure diseases, physican first, scientist second, writer third but he doesn’t separate this.  In older times scientists wrote to think and true today. How we visualize the word, or use our hands, is similar.  He takes the word translational research very seriously.  Can you say in one sentence how this will help patients in three years?
There are multitude ways of love for science.
Dr. Pinela: loved asking big question and loved storytelling but asking bigger questions. Moved from Columbia and moved to US; loved the freedom and government funding situation at that time.  Need the training and mentorship so mentors are a very big aspect in innovation as it led her to entrepreneurship.  We need to use technology to disrupt and innovate.
Nsikin:  A lot of mentors nurture curiosity.  People like to see them in that story of curiosity.  That is how is bases the PBS science videos: did  a study on engagement and people wants a morality, and a science identity (an inner nerd in all of us i.e. spark the interest).  The feedback if they focus on this has been positive.

“If the whole world switches to open access since the scholarly community wants this, it would be a world without subscriptions”

Reporter: Aviva Lev-Ari, UC, Berkeley, PhD’83, Editor-in-Chief, PharmaceuticalIntelligence.com – Open Access since 4/2012, 1,585,184 e-Readers, 5,503 articles. @AVIVA1950 is followed by 360 who’s Followers are 2.5 Millions

 

Why did UC decide to end negotiations today?

Elsevier made a new, quite complex, but novel proposal to us at the end of January. On Monday, our negotiating team gave them a written response outlining our appreciation for Elsevier’s effort, but saying that conditions had to be met for us to sign a contract, and that we thought we were pretty far apart. We knew if they couldn’t accommodate us, there was not much point in continuing to negotiate at this time.

Elsevier wanted to keep meeting with us, and we have a meeting scheduled for tomorrow (Friday), but yesterday they approached our faculty directly — faculty who are editors of Elsevier journals, who they have working relationships with — and also the media, and presented a rosy view of the offer they’d made to us. Their characterization of the offer left things out, and they didn’t mention what we’d proposed as conditions. They went public with it. So, we announced the end.

We knew all along it was going to be difficult for Elsevier to change its ways to our satisfaction. We had hoped they’d see the light, that the publishing industry is changing, and that they could help lead the way.

What did each side want the most, and why?

From the very beginning, we had two goals: a reduction in costs — we pay about $11 million a year to Elsevier in subscription fees, which is 25 percent of UC system-wide journal costs — and default open access publication for UC authors: that is, that Elsevier would publish an author’s work open access unless the author didn’t want to. This is consistent with the UC faculty senate’s goal of all work being published open access.

We also wanted a contract that integrated a paid subscription with open access publishing fees. It would have been a transformative agreement, one that would shift payments for reading journal articles into payments for publishing them, and publishing them open access.

Elsevier eventually offered to do something like what we wanted, for open access, but they wanted to charge us a lot more. Our current calculations are that they would have increased the amount of our payments by 80 percent — an additional $30 million over a three-year contract.

Open access would eventually mean fewer subscriptions for Elsevier. But we don’t think they would lose, in the long run, by charging for publishing rather than by charging for reading. The transition the industry is making to open access is a feasible path forward, so that more universities don’t cancel their licenses for the same reasons we did.

If the whole world switches to open access, which we think it will at some point since the scholarly community wants this, it would be a world without subscriptions. But it would be a world where people would still want and need to publish their work in peer-reviewed journals, and there’s always a cost for that.

Have other universities made the same decision?

In the U.S., we’re the first university system to do this with open access as the main issue.

But all of the universities in Germany canceled two years ago for the same reason. The Max Planck Society (the leading research organization in Germany) also did. The university alliance in Sweden canceled last spring, and the university alliance in Hungary canceled in December. Several other national alliances in Europe are trying to negotiate a similar contract with Elsevier.

Is this a goal of UC, to be a model institution for open access?

Conclusions

 

Introduction

Members of our Team published 5,295 articles, in the period between 4/2012 to 4/10/2018, and engaged in Comment Exchanges with Global Scientists Online. 1,412,106 eReaders had viewed our articles and 7,283 scientific comments are included in the Journal Archive.

Team Members’ Profile

Team Profile: DrugDiscovery @LPBI Group – A BioTech Start Up submitted for Funding Competition to MassChallenge Boston 2016 Accelerator

In our Scientific Agora: Multi Scientific Comment exchanges between Global e-Readers Scientists and LPBI’s Scientists/Experts/Authors/Writers take place. In this curation I am presenting four articles that generated dozens of scientific comments and multifaceted exchanges.

The Voice of Aviva Lev-Ari, PhD, RN:

It is my strongest conviction on the merit of the following features of Global SHARING the Scientific product, aka “An Article written by a Scientist” in the Digital Scientific Publishing Age:

  • Every new article published in Open Access Journals contributes to mitigate the most acute challenge of the e-Scientific Publishing industry today: Information Obsolescence – the newness of findings
  • Every new article published in Open Access Journals contributes AND in the Subscription-based Journals contributes to the second most acute challenge of of the e-Scientific Publishing industry today: Information Explosion – the volume of findings
  • The Scientific Agora as presented, below, in four Case Studies is an optimal means for Global SHARING in Real Time scientific knowledge deriving from clinical expertise and lab experience of all the participants in the Agora. REAL TIME means minimization of the negative impact of the most acute challenge of of the e-Scientific Publishing industry today: Information Obsolescence 
  • Knowledge SHARING of our Scientists articles occurs among two FORUMS:

Forum One, is the Scientists that joined the comment exchanges between the Article Author and other members of our Team on a given Scientific product, aka “An Article written by a Scientist”

Forum Two, is the Global Universe of Scientists that (a) are e-mail Followers opting to our Open Access Journal free subscription and (b) eReaders of our Journal that did not yet opt to follow the Journal by e-mail, a robust crowd of +1.4 Million Scientists

  • We mitigate the negative impact of the second most acute challenge of the e-Scientific Publishing industry today: Information Explosion by our own developed and advanced achievements reached in the practice of
  1. Development of the Methodology for Curation of Scientific Findings, Curation of Scientific Content @Leaders in Pharmaceutical Business Intelligence (LPBI) Group, Boston
  2. Application of the Methodology for Curation of Scientific Findings in a BioMed e-Series of 16-Volumes in Medicine and Life Sciences on Amazon.com

electronic Table of Contents (eTOCs) of each Volume in the SIXTEEN Volume BioMed e-Series

In 2016, LPBI’s BioMed e-Series was Submitted for Nomination for 2016 COMMUNICATION AWARD FOR EXCELLENCE IN REPORTING SCIENCE, MEDICINE AND ENGINEERING – Reference #: 9076095, on 1/27/2016

https://pharmaceuticalintelligence.com/biomed-e-books/

  • Lastly, It is my strong belief that the Methodology of Curation will become a major tool used in Content creation for Curriculum Development in Medical Schools, in the Life Sciences and Healthcare Allied professions.
  • We have pioneered and showed the way BY EXAMPLE, +5,200 Scientific products, aka “An Article written by a Scientist” constitute our Journal Archive created by content curation
  • More New e-Book Titles are coming in 2018-2019 in LPBI’s BioMed e-Series.
  • More e-Scientific Publishers will use the Methodology of Creation of electronic Table of Contents of e-Books by combing Archives by very experienced subject matter Editors.
  • Global SHARING of Information became best practice for Academic Course Contents in the last ten years
  • On-Line Degrees are spreading in many disciplines and are offered by very many colleges, including the Ivy League
  • Open Access Scientific Journals is the FUTURE of the e-Scientific Publishing Industry.

 

Case Study #1:

  • Is the Warburg Effect the Cause or the Effect of Cancer: A 21st Century View?

Author: Larry H. Bernstein, MD, FCAP

  1. This is OUTSTANDING.

    Now we need a “shortcliff” post to follow one chart that traces the dynamic process, no reader shall get lost inside any of the process boxes.

  2. Really nice overview and very interesting metabolic changes.
    However, related to the title, the cancerous changes- event always comes first before lactate preferred metabolism comes into place. Right?

  3. This is what has been inferred. So if that is the premise, then the mutation would be the first event. That position has been successfully challenged and also poses a challenge to the proper view of genomic discovery. The real event may very well be the ongoing oxidative stress with aging, and decreased physiochemical reserve.

    I haven’t developed the whole picture. Nitric oxide and nitrosylation contribute to both vascular relaxation and vasoconstriction, which is also different in major organs. The major carriers of H+ are NADH and FADH2. Electron transport is in the ETC in mitochondria. I called attention to the “escape” of energy in aerobic glycolysis. As disease ensues, it appears that lactate generation is preferential as the mitochondrion takes up substrate from gluconeogenesis. Whether it is an endotoxic shock or a highly malignant fast growing tumor, the body becomes trapped in “autocatabolism”. So the tumor progresses, apoptosis is suppressed, and there is a loss of lean body mass.
    All of this is tied to genetic instability.

    We see the genetic instability as first because of the model DNA–RNA–protein. We don’t have a map.

  4. It is a very nice report. I did work for a short time to develop compounds to block the glucose uptake especially using glucose-mimics. I wonder is there any research on this area going on now?

  5. Thanks. I have been researching this exhaustively. There are even many patents trying to damp this down. You were on the right track. The biggest problem has been multidrug resistance and tumor progression.

  8. Martin Canizales • Warburg effect (http://www.cellsignal.com/reference/pathway/warburg_effect.html), is responsible of overactivation of the PI3K… the produced peroxide via free radicals over activate the cyclooxigenase and consequently the PI3K pathway activating there, the most important protein-kinase ever described in the last mmmh, 60-70 years? maybe… to broke the Warburg effect, will stop the PI3K activation (http://www.cellsignal.com/reference/pathway/Akt_PKB.html) then all the cancer protein related with the generation of tumor (pAKT,pP70S6K, Cyclin D1, HIF1, VEGF, EGFrc, GSK, Myc, etc, etc, etc), will get down regulation. That is what happen, when I knock down the new protein-kinase in pancreatic cancer cell lines… stable KD of pancreatic cancer cell lines divide very-very-veeeery slow (by Western blotting, cyclin D1 disapear, VEGF, HIF1a, MyC, pAKT, pP70S6K, GSK, and more and more also has, very-very few consume of glucose [diabetes and cancer]. Stable cells can be without change the media for 3 weeks and the color doesn’t change, cells divide but VERY slow and are alive [longevity]) are not able to generate xenograft tumors related, to scramble shRNA stable cell lines. When, we broke the warburg effect, the protein kinase get’s down as well all the others. Is the same, with bacteria infections…. bacteria infections, has many things to teach us about cancer and cell proliferation (http://www.ncbi.nlm.nih.gov/pubmed/22750098)

    • The emphasis on p13 and the work on pancreatic cancer is very interesting. I’ll check the references you give. The Warburg effect is still metabolic, and it looks like you are able to suppress the growth of either cancer cells or bacteria. The outstanding question is whether you can get a head start on the SIR transition to sepsis to severe sepsis to MODS, to shock.

      It looks like an article will be necessary after your work is accepted for publication. Thanks a lot for the response.

    Also, when this protein-kinase is over expressed… UCP1 get down..then, less mitochondria, consequently less aerobic cell functions…in adipose tissue, less mitochondria promote the differentiation of BAT (Brown Adipose Tissue) to, WAT (White Agipose Tissue). Has relation with AS160 phosphorylation, Glut4 membrane translocation, promote the GABA phosphorylation (schizophrenia-autism), neuronal differentiation (NPCs:Neural Progenitor Cells), dopaminergic cell differentiation….

    Informative article especially concerning activation of HIF under normoxic conditions. Recently, a paper has come out showing patients showing symptoms of mood disorder having increased expression of Hif1a. Also, there are reports that Hif1a is important in development of certain tissue types.

  18. COLOURS AND LIFE. The basic idea of this theory is that the oxidation of hydrogen and carbon atoms, arising from the degradation of carbohydrates, is by two distinct processes based on oxidation-reduction electron transfer and photochemical process of energy release on the basis of color complementary, predominance of one or another depending on intracellular acid-base balance. I can not understand why nobody wants to do this experiment. I’m sure this assumption hides a truth. Before considering it a fiction to be checked experimentally. I would like to present a research project that concerns me for a long time that I can not experience myself.
    Involuntarily, after many years of searching, I have concluded that in the final biological oxidation, in addition to the oxidation-reduction electron transfer occurs photo-chemical process, accordance to the principle of color complementary energy transfer. I imagine an experiment that might be relevant (sure it can be improved). In my opinion, if this hypothesis proves true, one can control the energy metabolism of the cell by chromotherapy, as the structures involved are photosensitive and colorful. I would be very happy if this experiment were done under your leadership. Sincerely yours Dr. Viorel Bungau

    INNER LIGHT – LIGHT OF LIFE.
    CHROMOTHERAPY AND THE IMPLICATIONS IN THE METABOLISM OF THE NORMAL AND NEOPLASTIC CELL. “Chlorophyll and hemoglobin pigments of life porphyrin structure differs only in that chlorophyll is green because of magnesium atoms in the structure, and hemoglobin in red because of iron atoms in the structure. This is evidence of the common origin of life.” (Heilmeyer) We propose an experiment to prove that the final biological oxidation, in addition to its oxidation-reduction, with formation of H2O and CO2, there is a photochemical effect, by which energy is transferred from the H atom, or C, process is done selct, the colors, complementary colors on the basis of the structures involved are colored (red hemoglobin Fe, Mg chlorophyll green, blue ceruloplasmin Cu, Fe cytochrome oxidase red, green cytochrome oxidase with Cu etc.). The basic idea is that if life pigments (chlorophyll, hemoglobin, cytochromes), which provides energy metabolism of the cell, are colored, we can control their activities through chromotherapy, on the basis of complementary color and energy rebalance the body, with a figured X- body-colored-ray.
    In my opinion, at the basis of malign transformation is a disturbance of energetical metabolism, which reached a level that cell can not correct (after having succeeded before, many times), disturbance that affects the whole body in different degrees and requires corection from outside starting from the ideea that the final biological oxidizing takes place through photochemical process with releasing and receieving energy. “Duality of cytochrome oxidase. Proliferation (growth) and Differentiation (maturation) cell.” Cytochrome oxidase is present in two forms, depending on the context of acid-base internal environment : 1.- Form acidic (acidosis), which contains two Iron atoms, will be red, will absorb the additional green energy of the hydrogen atom, derived from carbohydrates, with formation of H2O, metabolic context that will promote cell proliferation. 2.-Form alkaline (alkalosis), containing two copper atoms, will be green, will absorb the additional red energy of the carbon atom, derived from carbohydrates, with formation of CO2, metabolic context that will promote cell differentiation. Cytochrome oxidase structure has two atoms of copper. It is known that in conditions of acidosis (oxidative potential), the principle electronegativity metals, copper is removed from combinations of the Iron. So cytochrome oxidase will contain two atoms of iron instead of copper atoms, which changes its oxidation-reduction potential, but (most important), and color. If the copper was green, the iron is red, which radically change its absorption spectrum, based on the principle of complementary colors.

    In my opinion, at the basis of malign transformation is a disturbance of energetical metabolism, which reached a level that cell can not correct (after having succeeded before, many times), disturbance that affects the whole body in different degrees and requires corection from outside starting from the ideea that the final biological oxidizing takes place through photochemical process with releasing and receieving energy. If the structures involved in biological oxidation finals are colored, then their energy absorption is made based on the principle of complementary colors. If we can determine the absorption spectrum at different levels, we can control energy metabolism by chromotherapy – EXOGENOUS MONOCHROMATIC IRRADIATION . Energy absorption in biological oxidation process itself, based on complementary colors, the structures involved (cytochromes), is the nature of porphyrins, in combination with a metal becomes colored, will absorb the complementary color, corresponding to a specific absorption spectrum, it will be in – ENDOGENOUS MONOCHROMATIC IRRADIATION.
    This entitles us to believe that: In photosynthesis, light absorption and its storage form of carbohydrates, are selected, the colors, as in cellular energy metabolism, absorption of energy by the degradation of carbohydrates, is also done selectively, based on complementary colors. In the final biological oxidation, in addition to an oxidation-reduction process takes place and a photo-chemical process,based on complementary colors, the first in the electron transfer, the second in the energy transfer. So, in the mitochondria is a process of oxidation of atoms C and H, derived from carbohydrates, with energy release and absorption of its selection (the color), by the structures involved, which is the nature of porphyrins, are photosensitive and colorful, if we accept as coenzymes involved, containing a metal atom gives them a certain color, depending on the state of oxidation or reduction (red ferment of Warburg with iron, all copper cerloplasmin blue, green chlorophyll magnesium, red iron hemoglobin, green cytochrome oxidase with copper, etc.)
    According to the principle electronegativity metals, under certain conditions the acid-base imbalance (acidosis), iron will replace copper in combination , cytocromoxidase became inactive, leading to changing oxidation-reduction potential, BUT THE COLOR FROM GREEN, TO REED, to block the final biological oxidation and the appearance of aerobic glycolysis. In connection with my research proposal, to prove that the final biological oxidation, in addition to an oxidation-reduction process takes place and a photo-chemical process, the first in the electron transfer, the second in the energy transfer.
    I SUGGEST TO YOU AN EXPERIMENT:

    TWO PLANTS, A RED (CORAILLE) LIGHT ONLY, IN BASIC MEDIUM, WITH ADDED COPPER, WILL GROW, FLOWER AND FRUIT WILL SHORT TIME, AND THE OTHER ONLY GREEN LIGHT (TOURQUOISE), IN AN ACID MEDIUM, WITH ADDED COPPER CHELATOR , WHICH GROWS THROUGHOUT WILL NOT GROW FLOWERS AND FRUIT WILL DO.

    CULTURE OF NEOPLASTIC TISSUE, IRRADIATED WITH MONOCHROMATIC GREEN ( TOURQUOISE) LIGHT, IN AN ALKALINE MEDIUM, WITH ADDED COPPER, WILL IN REGRESSION OF THE TISSUE CULTURE.

    CULTURE OF NEOPLASTIC TISSUE, IRRADIATED WITH RED ( CORAILLE) LIGHT, IN AN ACID MEDIUM, WITH ADDED COPPER CHELATOR, WILL LEAD TO EXAGERATED AND ANARCHICAL MULTIPLICATION.
    If in photosynthesis is the direct effect of monochromatic irradiation, in the final biological oxidation effect is reversed. Exogenous irradiation with green, induces endogenous irradiation with red, and vice versa. A body with cancer disease will become chemically color “red”- Acid -(pH, Rh, pCO2, alkaline reserve), and in terms of energy, green (X-body-colored-ray). A healthy body will become chemically color “green”-Alkaline – (as evidenced by laboratory), and in terms of energy, red (visible by X-body-colored-ray). Sincerely, Dr. Viorel Bungau

    Cytochrome oxidase structure has two atoms of copper. It is known that in conditions of acidosis (oxidative potential), the principle electronegativity metals, copper is removed from combinations of the Iron. So cytochrome oxidase will contain two atoms of iron instead of copper atoms, which changes its oxidation-reduction potential, but (most important), and color. If the copper was green, the iron is red, which radically change its absorption spectrum, based on the principle of complementary colors. If neoplastic cells, because acidosis is overactive acid form of cytochrome oxidase (red with iron atoms), which will absorb the additional green energy hydrogen atom (exclusively), the production of H20 , so water will prevail, in Schizophrenia , neuronal intracellular alkaline environment, will promote the basic form of cytochrome oxidase (green with copper atoms), which will oxidize only carbon atoms, the energy absorption of red (complementary) and production of CO2, so the fire will prevail. Drawn from this theory interdependent relationship between water and fire, of hydrogen(H2O) and carbon(CO2) ,in a controlled relationship with oxygen (O2). If photosynthesis is a process of reducing carbon oxide(CO2) and hydrogen oxide(H2O), by increasing electronegativity of C and H atoms, with the electrons back to oxygen, which will be released in the mitochondria is a process of oxidation of atoms C and H, derived from carbohydrates, with energy release and absorption of its selection (the color), by the structures involved, which is the nature of porphyrins, are photosensitive and colorful. It means that matter and energy in the universe are found in a relationship based on complementary colors, each color of energy, corresponding with a certain chemical structure. In my opinion, at the basis of malign transformation is a disturbance of energetical metabolism, which reached a level that cell can not correct (after having succeeded before, many times), disturbance that affects the whole body in different degrees and requires corection from outside starting from the ideea that the final biological oxidizing takes place through photochemical process with releasing and receieving energy. The final biological oxidation is achieved through a process of oxidation-reduction, while a photochemical process, based on the principle of complementary colors, if we accept as coenzymes involved, containing a metal atom gives them a certain color, depending on the state of oxidation or reduction (red ferment of Warburg with copper, all copper cerloplasmin blue, green chlorophyll magnesium, red iron hemoglobin,etc. If satisfied, the final biological oxidation is achieved by a photochemical mechanism (besides the oxidation-reduction), that energy is released based on complementary colors, means that we can control the final biological oxidation mechanism, irreversibly disrupted in cancer, by chromotherapy and correction of acid-base imbalance that underlies this disorder.We reached this conclusions studying the final biological oxidation, for understanding the biochemical mechanism of aerobic glycolysis in cancer. We found that cancer cell, energy metabolism is almost exclusively on hydrogen by oxidative dehydrogenation, due to excessive acidosis , coenzymes which makes carbon oxidation, as dormant (these coenzymes have become inactive). If we accept the nature of these coenzymes chloride (see Warburg ferment red), could be rectivate, by correcting acidosis (because that became leucoderivat), and by chromoterapie, on the basis of complementary colors. According to the principle electronegativity metals, under certain conditions the acid-base imbalance (acidosis), iron will replace copper in combination , cytocromoxidase became inactive (it contains two copper atoms) leading to changing oxidation-reduction potential, BUT THE COLOR FROM GREEN, TO REED, to block the final biological oxidation and the appearance of aerobic glycolysis.

    Malignant transformation occurs by energy metabolism imbalance in power generation purposes in the predominantly (exclusively) of the hydrogen atom of carbon oxidation is impossible. Thus at the cellular level will produce a multiplication (growth) exaggerated (exclusive), energy from hydrogen favoring growth, multiplication, at the expense of differentiation (maturation). Differentiation is achieved by energy obtained by oxidation of the carbon atom can not take, leading to carcinogenesis . The energy metabolism of the cell, an energy source is carbohydrate degradation, which is done by OXIDATIVE DEHYDROGENATION AND OXIDATIVE DECARBOXYLATION , to obtain energy and CO2 and H2O. In normal cells there is a balance between the two energy sources. If cancer cells, oxidation of the carbon atom is not possible, the cell being forced to summarize the only energy source available, of hydrogen. This disorder underlying malignant transformation of cells and affect the whole body, in various degrees, often managing to rebalance process, until at some point it becomes irreversible. The exclusive production of hydrogen energy will cause excessive multiplication, of immature cells, without functional differentiation. Exclusive carbon energy production will lead to hyperdifferentiation, hyperfunctional, multiplication is impossible. Normal cell is between two extremes, between some limits depending on the adjustment factors of homeostasis. Energy from energy metabolism is vital for cell (body). If the energy comes predominantly (or exclusively) by oxidation of the hydrogen atom, green energy, will occur at the structural level (biochemical), acidification of the cellular structures that will turn red, so WE HAVE MORPHOLOGICAL AND CHEMICAL STRUCTURES “RED”, WITH “GREEN” ENERGY. This background predisposes to accelerated growth, without differentiation, reaching up uncontrolled, anarchical. ENERGY STRUCTURE OF THE CELL BODY WOULD BE INN. If necessary energy cell derived mainly by oxidation of the carbon atom, red energy,cell structures will be colored green, will be alkaline(basic), so WE HAVE MORPHOLOGICAL AND CHEMICAL STRUCTURES “GREEN”, WITH “RED” ENERGY, on the same principle of complementarity. This context will lead hyperdifferentiation, hyperfunctional ,maturation, and grouth stops. ENERGY STRUCTURE OF THE CELL BODY WOULD BE YANG. If in photosynthesis, porphyrins chemicals group, whic be photosensitivity (their first feature), shows and a great affinity for metals with chelate forming and becoming colored (pigments of life), can absorb monochromatic light complementary, so if these pigments, which constitutes the group of chromoprotheine, in photosynthesis will achieve CO2 and H2O reduction the recovery of C, H respectively, and the issuance of and release of O, atoms as H and C that reduced the energy load, representing carbohydrates, is in the form of solar energy storage, in cellular energy metabolism, processes necessary life, energy will come from the degradation of substances produced in photosynthesis, the carbohydrates, by oxidative dehydrogenation and oxidative decarboxylation, through like substances, which form chelates with the metals, are colored, metals contained in the form of oxides of various colors(green Mg, red Fe, blue Cu,etc.),suffering from complementary color absorption process of reduction with H in case,if the oxidative dehydrogenation, when chelated metal pigment is red, becoming leucoderivat (colorless) by absorbing complementary color (green) of hydrogen, formation of H2O, or C, if the oxidative decarboxylation when chelated metallic pigment is green, energy absorbing additional, red energy of atom C, CO2 production, the process is identical. The process that lies at base cellular energy metabolism, takes place in the final biological oxidation, reducing the O atom in the form of metal oxide, in combination with photosensitive substance, porohyrin, colorful,absorbing complementary color, will reduce the O atom, with H and C, with the production of H2O and CO2. Green energy release of H atom in the oxidative dehydrogenation process, it is a process of”IRRADIATION MONOCHROMATIC ENDOGENOUS WITH GREEN”, and red energy release of C atom in the oxidative decarboxylation process, consists in an “IRRADIATION MONOCHROMATIC ENDOGENOUS WITH RED”. Porphyrin-metal combination in photosynthesis, the chelated form, by absorbing light in the visible spectrum, will be able to reduce to low and turn, C and H respectively, the state of oxide (CO2 and H2O),release of O. The final biological oxidation, the combination of metal-porphyrins in aerobically in the absence of light, will find in the oxidized state, so in the form of porphyrins and metal-oxide, will oxidize to C and H atom of hydrocarbonates, with formation of CO2 and H2O, or rather, will be reduced by C and H atom of hydrocarbonates,formation of CO2 and H2O, by absorbing energy produced by photosynthesis. If we can control the final biological oxidation, we can control cellular growth, thus multiplying, and on the other hand, maturation, so differentiation. Green energy will prevail if the cell (body) which multiplies (during growth), will in case of adult cell (functional) will prevail red energy . The two types of energy, that obtained by oxidative dehydrogenation , which will cause cell multiplication without differentiation , and that obtained by oxidative decarboxylation , which will be to stop proliferation, and will determine the differentiation (maturity, functionality). This process is carried out based on complementary colors, which are coenzymes oxidative dehydrogenation and oxidative decarboxylation is colored . It reveals the importance of acid-base balance, the predominance of the acidic or basic, as an acid structure (red), not only can gain energy from the carbon atom red (the principle of complementarity), but can not assimilate ( under the same principle). It must therefore acid-base balance of internal environment, and alkalinization his intake of organic substances by the electron donor. By alkalinization (addition of electrons) will occur neutralize acid structures, the red, they become leucoderivat, colorless, and inactive, while the basic, which because of acidosis became neutral, colorless and inactive, will be alkaline in electron contribution, will be in green, and will absorb red energy from the carbon atom. So, on two kinds of vital energy, it is clear correlation between the chemical structure of the cell(body),and type of energy that can produce and use. Thus a cell with acidic chemical structure, can produce only energy by oxidative dehydrogenation (green energy), because the acid can only be active coenzymes with acid chemical structure, red, will absorb the complementarity only green energy of hydrogen. Basic structures which should absorb red energy from carbon , are inactive due to acid environment, which in turn chemically in leucoderivat, so colorless structures, inactive. Conversion of these structures to normal, operation by alkalinization could be a long lasting process, therefore, we use parallel chromotherapy, based on the fact that these COENZYMES INVOLVED IN BIOLOGICAL OXIDATION FINALS ARE COLORED AND PHOTOSENSITIVE. Thus, exogenous irradiation with monochromatic green will neutralize, by complementarity, coenzymes red, acidic. In will reactivate alkaline coenzymes, which have become due acidosis leucoderivat, so colorless and inactive. Without producing CO2, carbonic anhydrase can not form H2CO3, severable and thus transferred through mitochondrial membrane. Will accumulate in the respiratory Flavin, OH groups, leading to excessive hydroxylation, followed by consecutive inclusion of amino (NH2). It is thus an imbalance between the hydrogenation-carboxylation and hydroxylation-amination, in favor of the latter. This will predominate AMINATION and HYDROXYLATION at the expense CARBOXYLATION and HYDROGENATION, leading to CONVERSION OF STRUCTURAL PROTEINS IN NUCLEIC ACIDS. Meanwhile, after chemical criteria not genetic, it synthesizes the remaining unoxidized carbon atoms, nucleic bases “de novo” by the same process of hydroxylation-amination, leading to THE SYNTHESIS OF NUCLEIC ACIDS “DE NOVO”.

If in photosynthesis, porphyrins chemicals group, whic be photosensitivity (their first feature), shows and a great affinity for metals with chelate forming and becoming colored (pigments of life), can absorb monochromatic light complementary, so if these pigments, which constitutes the group of chromoprotheine, in photosynthesis will achieve CO2 and H2O reduction the recovery of C, H respectively, and the issuance of and release of O, atoms as H and C that reduced the energy load, representing carbohydrates, is in the form of solar energy storage, in cellular energy metabolism, processes necessary life, energy will come from the degradation of substances produced in photosynthesis, the carbohydrates, by oxidative dehydrogenation and oxidative decarboxylation, through like substances, which form chelates with the metals, are colored, metals contained in the form of oxides of various colors(green Mg, red Fe, blue Cu,etc.),suffering from complementary color absorption process of reduction with H in case,if the oxidative dehydrogenation, when chelated metal pigment is red, becoming leucoderivat (colorless) by absorbing complementary color (green) of hydrogen, formation of H2O, or C, if the oxidative decarboxylation when chelated metallic pigment is green, energy absorbing additional, red energy of atom C, CO2 production, the process is identical. The process that lies at base cellular energy metabolism, takes place in the final biological oxidation, reducing the O atom in the form of metal oxide, in combination with photosensitive substance, porohyrin, colorful,absorbing complementary color, will reduce the O atom, with H and C, with the production of H2O and CO2. Green energy release of H atom in the oxidative dehydrogenation process, it is a process of”IRRADIATION MONOCHROMATIC ENDOGENOUS WITH GREEN”, and red energy release of C atom in the oxidative decarboxylation process, consists in an “IRRADIATION MONOCHROMATIC ENDOGENOUS WITH RED”. Porphyrin-metal combination in photosynthesis, the chelated form, by absorbing light in the visible spectrum, will be able to reduce to low and turn, C and H respectively, the state of oxide (CO2 and H2O),release of O. The final biological oxidation, the combination of metal-porphyrins in aerobically in the absence of light, will find in the oxidized state, so in the form of porphyrins and metal-oxide, will oxidize to C and H atom of hydrocarbonates, with formation of CO2 and H2O, or rather, will be reduced by C and H atom of hydrocarbonates,formation of CO2 and H2O, by absorbing energy produced by photosynthesis. If we can control the final biological oxidation, we can control cellular growth, thus multiplying, and on the other hand, maturation, so differentiation. Green energy will prevail if the cell (body) which multiplies (during growth), will in case of adult cell (functional) will prevail red energy . The two types of energy, that obtained by oxidative dehydrogenation , which will cause cell multiplication without differentiation , and that obtained by oxidative decarboxylation , which will be to stop proliferation, and will determine the differentiation (maturity, functionality). This process is carried out based on complementary colors, which are coenzymes oxidative dehydrogenation and oxidative decarboxylation is colored . It reveals the importance of acid-base balance, the predominance of the acidic or basic, as an acid structure (red), not only can gain energy from the carbon atom red (the principle of complementarity), but can not assimilate ( under the same principle). It must therefore acid-base balance of internal environment, and alkalinization his intake of organic substances by the electron donor. By alkalinization (addition of electrons) will occur neutralize acid structures, the red, they become leucoderivat, colorless, and inactive, while the basic, which because of acidosis became neutral, colorless and inactive, will be alkaline in electron contribution, will be in green, and will absorb red energy from the carbon atom. So, on two kinds of vital energy, it is clear correlation between the chemical structure of the cell(body),and type of energy that can produce and use. Thus a cell with acidic chemical structure, can produce only energy by oxidative dehydrogenation (green energy), because the acid can only be active coenzymes with acid chemical structure, red, will absorb the complementarity only green energy of hydrogen. Basic structures which should absorb red energy from carbon , are inactive due to acid environment, which in turn chemically in leucoderivat, so colorless structures, inactive. Conversion of these structures to normal, operation by alkalinization could be a long lasting process, therefore, we use parallel chromotherapy, based on the fact that these COENZYMES INVOLVED IN BIOLOGICAL OXIDATION FINALS ARE COLORED AND PHOTOSENSITIVE. Thus, exogenous irradiation with monochromatic green will neutralize, by complementarity, coenzymes red, acidic. In will reactivate alkaline coenzymes, which have become due acidosis leucoderivat, so colorless and inactive. Without producing CO2, carbonic anhydrase can not form H2CO3, severable and thus transferred through mitochondrial membrane. Will accumulate in the respiratory Flavin, OH groups, leading to excessive hydroxylation, followed by consecutive inclusion of amino (NH2). It is thus an imbalance between the hydrogenation-carboxylation and hydroxylation-amination, in favor of the latter. This will predominate AMINATION and HYDROXYLATION at the expense CARBOXYLATION and HYDROGENATION, leading to CONVERSION OF STRUCTURAL PROTEINS IN NUCLEIC ACIDS. Meanwhile, after chemical criteria not genetic, it synthesizes the remaining unoxidized carbon atoms, nucleic bases “de novo” by the same process of hydroxylation-amination, leading to THE SYNTHESIS OF NUCLEIC ACIDS “DE NOVO”.

    INCORE pointed out in detail about the general problem judging response and the stil missing quality in standardization:

    I did research in response evaluation and prediction for about 15y now and being honest: neither the clinical, nor the molecular biological data proved significant benefit in changing a strategy in patient diagnosis and / or treatment. I would state: this brings us back on the ground and not upon the sky. Additionally it means: we have to ´work harder on that and the WHO has to take responsibility: clinicians use a reponse classification without knowing, that this is just related to “ONE” experiment from the 70’s and that this experiment never had been rescrutinized (please read the Editorial I provided – we use a clinical response classification since more than 30 years worldwide (Miller et al. Cancer 1981) but it is useless !

  4. Dr. BB

    Thank you for your comment.
    Dr. Nir will reply to your comment.
    Regarding the Response Classification in use, it seems that the College of Oncology should champion a task force to revisit the Best Practice in use in this domain and issue a revised version or a new effort for a a new classification system for Clinical Response to treatment in Cancer.

  5. I’m sorry that I was looking for this paper again earlier and didn’t find it. I answered my view on your article earlier.

    This is a method demonstration, but not a proof of concept by any means. It adds to the cacophany of approaches, and in a much larger study would prove to be beneficial in treatment, but not a cure for serious prostate cancer because it is unlikely that it can get beyond the margin, and also because there is overtreatment at the cutoff of PSA at 4.0. There is now a proved prediction model that went to press some 4 months ago. I think that the pathologist has to see the tissue, and the standard in pathology now is for any result that is cancer, two pathologist or a group sitting together should see it. It’s not an easy diagnosis.

    ..Tumor heterogeneity is a ubiquitous phemomenon. In particular, there are important differences among the various types of gastrointestinal (GI) cancers in terms of tumor biology, treatment response and prognosis.

    ..This forms the principal basis for targeted therapy directed by tumor-specific testing at either the gene or protein level. Despite rapid advances in our understanding of targeted therapy for GI cancers, the impact on cancer survival has been marginal.

    ..Can tumor response to therapy be predicted, thereby improving the selection of patients for cancer treatment?

    ..In 2000 theNCI with the European Association for Research and Treatment of Cancer, proposed a replacement of 2D measurement with a decrease in the largest tumor diameter by 30% in one dimension. Tumor response as defined would translate into a 50% decrease for a spherical lesion

    ..We must rethink how we may better determine treatment response in a reliable, reproducible way that is aimed at individualizing the therapy of cancer patients.

    ..we must change the tools we use to assess tumor response. The new modality should be based on empirical evidence that translates into relevant and meaningful clinical outcome data.

    ..This becomes a conundrum of sorts in an era of ‘minimally invasive treatment’.

    ..integrated multidisciplinary panel of international experts – not sure that that will do it

    Several years ago i heard Stamey present the totality of his work at Stanford, with great disappointment over hsPSA that they pioneered in. The outcomes were disappointing.

    I had published a review of all of our cases reviewed for 1 year with Marguerite Pinto.
    There’s a reason that the physicians line up outside of her office for her opinion.
    The review showed that a PSA over 24 ng/ml is predictive of bone metastasis. Any result over 10 was as likely to be prostatitis, BPH or cancer.

    I did an ordinal regression in the next study with Gustave Davis using a bivariate ordinal regression to predict lymph node metastasis using the PSA and the Gleason score. It was better than any univariate model, but there was no followup.

    I reviewed a paper for Clin Biochemistry (Elsevier) on a new method for PSA, very different than what we are familiar with. It was the most elegant paper I have seen in the treatment of the data. The model could predict post procedural time to recurrence to 8 years.

    • I hope we are in agreement on the fact that imaging guided interventions are needed for better treatment outcome. The point I’m trying to make in this post is that people are investing in developing imaging guided intervention and it is making progress.

      Over diagnosis and over treatment is another issue altogether. I think that many of my other posts are dealing with that.

  6. Tumor response criteria: are they appropriate?

    Tumor heterogeneity is a problematic because of differences among the metabolic variety among types of gastrointestinal (GI) cancers, confounding treatment response and prognosis.
    This is in response to … a group of investigators from Sunnybrook Health Sciences Centre, University of Toronto, Ontario, Canada who evaluate the feasibility and safety of magnetic resonance (MR) imaging–controlled transurethral ultrasound therapy for prostate cancer in humans. Their study’s objective was to prove that using real-time MRI guidance of HIFU treatment is possible and it guarantees that the location of ablated tissue indeed corresponds to the locations planned for treatment.
    1. There is a difference between expected response to esophageal or gastric neoplasms both biologically and in expected response, even given variability within a class. The expected time to recurrence is usually longer in the latter case, but the confounders are – age at time of discovery, biological time of detection, presence of lymph node and/or distant metastasis, microscopic vascular invasion.
    2. There is a long latent period in abdominal cancers before discovery, unless a lesion is found incidentally in surgery for another reason.
    3. The undeniable reality is that it is not difficult to identify the main lesion, but it is difficult to identify adjacent epithelium that is at risk (transitional or pretransitional). Pathologists have a very good idea about precancerous cervical neoplasia.

    The heterogeneity rests within each tumor and between the primary and metastatic sites, which is expected to be improved by targeted therapy directed by tumor-specific testing. Despite rapid advances in our understanding of targeted therapy for GI cancers, the impact on cancer survival has been marginal.

    The heterogeneity is a problem that will take at least another decade to unravel because of the number of signaling pathways and the crosstalk that is specifically at issue.

    I must refer back to the work of Frank Dixon, Herschel Sidransky, and others, who did much to develop a concept of neoplasia occurring in several stages – minimal deviation and fast growing. These have differences in growth rates, anaplasia, and biochemical. This resembles the multiple “hit” theory that is described in “systemic inflammatory” disease leading to a final stage, as in sepsis and septic shock.
    In 1920, Otto Warburg received the Nobel Prize for his work on respiration. He postulated that cancer cells become anaerobic compared with their normal counterpart that uses aerobic respiration to meet most energy needs. He attributed this to “mitochondrial dysfunction. In fact, we now think that in response to oxidative stress, the mitochondrion relies on the Lynen Cycle to make more cells and the major source of energy becomes glycolytic, which is at the expense of the lean body mass (muscle), which produces gluconeogenic precursors from muscle proteolysis (cancer cachexia). There is a loss of about 26 ATP ~Ps in the transition.
    The mitochondrial gene expression system includes the mitochondrial genome, mitochondrial ribosomes, and the transcription and translation machinery needed to regulate and conduct gene expression as well as mtDNA replication and repair. Machinery involved in energetics includes the enzymes of the Kreb’s citric acid or TCA (tricarboxylic acid) cycle, some of the enzymes involved in fatty acid catabolism (β-oxidation), and the proteins needed to help regulate these systems. The inner membrane is central to mitochondrial physiology and, as such, contains multiple protein systems of interest. These include the protein complexes involved in the electron transport component of oxidative phosphorylation and proteins involved in substrate and ion transport.
    Mitochondrial roles in, and effects on, cellular homeostasis extend far beyond the production of ATP, but the transformation of energy is central to most mitochondrial functions. Reducing equivalents are also used for anabolic reactions. The energy produced by mitochondria is most commonly thought of to come from the pyruvate that results from glycolysis, but it is important to keep in mind that the chemical energy contained in both fats and amino acids can also be converted into NADH and FADH2 through mitochondrial pathways. The major mechanism for harvesting energy from fats is β-oxidation; the major mechanism for harvesting energy from amino acids and pyruvate is the TCA cycle. Once the chemical energy has been transformed into NADH and FADH2 (also discovered by Warburg and the basis for a second Nobel nomination in 1934), these compounds are fed into the mitochondrial respiratory chain.
    The hydroxyl free radical is extremely reactive. It will react with most, if not all, compounds found in the living cell (including DNA, proteins, lipids and a host of small molecules). The hydroxyl free radical is so aggressive that it will react within 5 (or so) molecular diameters from its site of production. The damage caused by it, therefore, is very site specific. The reactions of the hydroxyl free radical can be classified as hydrogen abstraction, electron transfer, and addition.
    The formation of the hydroxyl free radical can be disastrous for living organisms. Unlike superoxide and hydrogen peroxide, which are mainly controlled enzymatically, the hydroxyl free radical is far too reactive to be restricted in such a way – it will even attack antioxidant enzymes. Instead, biological defenses have evolved that reduce the chance that the hydroxyl free radical will be produced and, as nothing is perfect, to repair damage.
    Currently, some endogenous markers are being proposed as useful measures of total “oxidative stress” e.g., 8-hydroxy-2’deoxyguanosine in urine. The ideal scavenger must be non-toxic, have limited or no biological activity, readily reach the site of hydroxyl free radical production (i.e., pass through barriers such as the blood-brain barrier), react rapidly with the free radical, be specific for this radical, and neither the scavenger nor its product(s) should undergo further metabolism.
    Nitric oxide has a single unpaired electron in its π*2p antibonding orbital and is therefore paramagnetic. This unpaired electron also weakens the overall bonding seen in diatomic nitrogen molecules so that the nitrogen and oxygen atoms are joined by only 2.5 bonds. The structure of nitric oxide is a resonance hybrid of two forms.
    In living organisms nitric oxide is produced enzymatically. Microbes can generate nitric oxide by the reduction of nitrite or oxidation of ammonia. In mammals nitric oxide is produced by stepwise oxidation of L-arginine catalyzed by nitric oxide synthase (NOS). Nitric oxide is formed from the guanidino nitrogen of the L-arginine in a reaction that consumes five electrons and requires flavin adenine dinucleotide (FAD), flavin mononucleotide (FMN) tetrahydrobiopterin (BH4), and iron protoporphyrin IX as cofactors. The primary product of NOS activity may be the nitroxyl anion that is then converted to nitric oxide by electron acceptors.
    The thiol-disulfide redox couple is very important to oxidative metabolism. GSH is a reducing cofactor for glutathione peroxidase, an antioxidant enzyme responsible for the destruction of hydrogen peroxide. Thiols and disulfides can readily undergo exchange reactions, forming mixed disulfides. Thiol-disulfide exchange is biologically very important. For example, GSH can react with protein cystine groups and influence the correct folding of proteins, and it GSH may play a direct role in cellular signaling through thiol-disulfide exchange reactions with membrane bound receptor proteins (e.g., the insulin receptor complex), transcription factors (e.g., nuclear factor κB), and regulatory proteins in cells. Conditions that alter the redox status of the cell can have important consequences on cellular function.
    So the complexity of life is not yet unraveled.

    Can tumor response to therapy be predicted, thereby improving the selection of patients for cancer treatment?
    The goal is not just complete response. Histopathological response seems to be related post-treatment histopathological assessment but it is not free from the challenge of accurately determining treatment response, as this method cannot delineate whether or not there are residual cancer cells. Functional imaging to assess metabolic response by 18-fluorodeoxyglucose PET also has its limits, as the results are impacted significantly by several variables:

    • tumor type
    • sizing
    • doubling time
    • anaplasia?
    • extent of tumor necrosis
    • type of antitumor therapy and the time when response was determined.
    The new modality should be based on individualized histopathology as well as tumor molecular, genetic and functional characteristics, and individual patients’ characteristics, a greater challenge in an era of ‘minimally invasive treatment’.
    This listing suggests that for every cancer the following data has to be collected (except doubling time). If there are five variables, the classification based on these alone would calculate to be very sizable based on Eugene Rypka’s feature extraction and classification. But looking forward, time to remission and disease free survival are additionally important. Treatment for cure is not the endpoint, but the best that can be done is to extend the time of survival to a realistic long term goal and retain a quality of life.

    • Dr. Larry,

      Thank you for this comment.

      Please carry it as a stand alone post, Dr. Ritu will refer to it and reference it in her FORTHCOMING pst on Tumor Response which will integrate multiple sources.

      Please execute my instruction

      Thank you

    • Thank you Larry for this educating comment. It explains very well why the Canadian investigators did not try to measure therapy response!

      What they have demonstrated is the technological feasibility of coupling a treatment device to an imaging device and use that in order to guide the treatment to the right place.

      the issue of “choice of treatment” to which you are referring is not in the scope of this publication.
      The point is: if one treatment modality can be guided, other can as well! This should encourage others, to try and develop imaging-based treatment guidance systems.

  7. The crux of the matter in terms of capability is that the cancer tissue, adjacent tissue, and the fibrous matrix are all in transition to the cancerous state. It is taught to resect leaving “free margin”, which is better aesthetically, and has had success in breast surgery. The dilemma is that the patient may return, but how soon?

    • Correct. The philosophy behind lumpectomy is preserving quality of life. It was Prof. Veronesi (IEO) who introduced this method 30 years ago noticing that in the majority of cases, the patient will die from something else before presenting recurrence of breast cancer..

      It is well established that when the resection margins are declared by a pathologist (as good as he/she could be) as “free of cancer”, the probability of recurrence is much lower than otherwise.

  8. Dr. Larry,

    To assist Dr. Ritu, PLEASE carry ALL your comments above into a stand alone post and ADD to it your comment on my post on MIS

    Thank you

  9. Great post! Dr. Nir, can the ultrasound be used in conjunction with PET scanning as well to determine a spatial and functional map of the tumor. With a disease like serous ovarian cancer we typically see an intraperitoneal carcimatosis and it appears that clinicians are wanting to use fluorogenic probes and fiberoptics to visualize the numerous nodules located within the cavity Also is the technique being used mainy for surgery or image guided radiotherapy or can you use this for detecting response to various chemotherapeutics including immunotherapy.

    • Ultrasound can and is actually used in conjunction with PET scanning in many cases. The choice of using ultrasound is always left to the practitioner! Being a non-invasive, low cost procedure makes the use of ultrasound a non-issue. The down-side is that because it is so easy to access and operate, nobody bothers to develop rigorous guidelines about using it and the benefits remains the property of individuals.

      In regards to the possibility of screening for ovarian cancer and characterising pelvic masses using ultrasound I can refer you to scientific work in which I was involved:

  10. totally true and i am very thankfull for these briliant comments.

    Remember: 10years ago: every cancer researcher stated: “look at the tumor cells only – forget the stroma”. The era of laser-captured tumor-cell dissection started. Now , everyone knows: it is a system we are looking at and viewing and analyzing tumor cells only is really not enough.

    So if we would be honest, we would have to declare, that all data, which had been produced 13-8years ago, dealing with laser capture microdissection, that al these data would need a re-scrutinization, cause the influence of the stroma was “forgotten”. I ‘d better not try thinking about the waisted millions of dollars.

    If we keep on being honest: the surgeon looks at the “free margin” in a kind of reductionable model, the pathologist is more the control instance. I personally see the pathologist as “the control instance” of surgical quality. Therefore, not the wish of the surgeon is important, the objective way of looking into problems or challenges. Can a pathologist always state, if a R0-resection had been performed ?

    The use of the Resectability Classification:
    There had been many many surrogate marker analysis – nothing new. BUT never a real substantial well tought through structured analysis had been done: mm by mm by mm by mm and afterwards analyzing that by a ROC analysis. BUt against which goldstandard ? If you perform statistically a ROC analysis – you need a golstandard to compare to. Therefore what is the real R0-resectiòn? It had been not proven. It just had been stated in this or that tumor entity that this or that margin with this margin free mm distance or that mm distance is enough and it had been declared as “the real R0-classification”. In some organs it is very very difficult and we all (surgeons, pathologists, clinicians) that we always get to the limit, if we try interpretating the R-classification within the 3rd dimension. Often it is just declared and stated.

    Otherwise: if lymph nodes are negative it does not mean, lymph nodes are really negative, cause up to 38% for example in upper GI cancers have histological negative lymph nodes, but immunohistochemical positive lymph nodes. And this had been also shown by Stojadinovic at el analyzing the ultrastaging in colorectal cancer. So the 4th dimension of cancer – the lymph nodes / the lymphatic vessel invasion are much more important than just a TNM classification, which unfortunately does often not reflect real tumor biology.

    AS we see: cancer has multifactorial reasons and it is necessary taking the challenge performing high sophisticated research by a multifactorial and multidisciplinary manner.

    Again my deep and heartly thanks for that productive and excellent discussion !

    • Dr. BB,

      Thank you for your comment.

      Multidisciplinary perspectives have illuminated the discussion on the pages of this Journal.

      Eager to review Dr. Ritu’s forthcoming paper – the topic has a life of its own and is embodied in your statement:

      “the 4th dimension of cancer – the lymph nodes / the lymphatic vessel invasion are much more important than just a TNM classification, which unfortunately does often not reflect real tumor biology.”

    • Thank you BB for your comment. You have touched the core limitation of healthcare professionals: how do we know that we know!

      Do we have a reference to each of the test we perform?

      Do we have objective and standardise quality measures?

      Do we see what is out-there or are we imagining?

      The good news: Everyday we can “think” that we learned something new. We should be happy with that, even if it is means that we learned that yesterday’s truth is not true any-more and even if we are likely to be wrong again…:)

      But still, in the last decades, lots of progress was made….

  11. Dr. Nir,
    I thoroughly enjoyed reading your post as well as the comments that your post has attracted. There were different points of view and each one has been supported with relevant examples in the literature. Here are my two cents on the discussion:
    The paper that you have discussed had the objective of finding out whether real-time MRI guidance of treatment was even possible and if yes, and also if the treatment could be performed in accurate location of the ROI? The data reveals they were pretty successful in accomplishing their objective and of course that gives hope to the imaging-based targeted therapies.
    Whether the ROI is defined properly and if it accounts for the real tumor cure, is a different question. Role of pathologists and the histological analysis they bring about to the table cannot be ruled out, and the absence of a defined line between the tumor and the stromal region in the vicinity is well documented. However, that cannot rule out the value and scope of imaging-based detection and targeted therapy. After all, it is seminal in guiding minimally invasive surgery. As another arm of personalized medicine-based cure for cancer, molecular biologists at MD Anderson have suggested molecular and genetic profiling of the tumor to determine genetic aberrations on the basis of which matched-therapy could be recommended to patients. When phase I trial was conducted, the results were obtained were encouraging and the survival rate was better in matched-therapy patients compared to unmatched patients. Therefore, everytime there is more to consider when treating a cancer patient and who knows a combination of views of oncologists, pathologists, molecular biologists, geneticists, surgeons would device improvised protocols for diagnosis and treatment. It is always going to be complicated and generalizations would never give an answer. Smart interpretations of therapies – imaging-based or others would always be required!

    Ritu

    • Dr. Nir,
      One of your earlier comments, mentioned the non invasiveness of ultrasound, thus, it’s prevalence in use for diagnosis.

      This may be true for other or all areas with the exception of Mammography screening. In this field, an ultrasound is performed only if a suspected area of calcification or a lump has been detected in the routine or patient-initiated request for ad hoc mammography secondery to patient complain of pain or patient report of suspected lump.

      Ultrasound in this field repserents ascalation and two radiologists review.

      It in routine use for Breast biopsy.

    • Thanks Ritu for this supporting comment. The worst enemy of finding solutions is doing nothing while using the excuse of looking for the “ultimate solution” . Personally, I believe in combining methods and improving clinical assessment based on information fusion. Being able to predict, and then timely track the response to treatment is a major issue that affects survival and costs!

    INCORE pointed out in detail about the general problem judging response and the stil missing quality in standardization:

    I did research in response evaluation and prediction for about 15y now and being honest: neither the clinical, nor the molecular biological data proved significant benefit in changing a strategy in patient diagnosis and / or treatment. I would state: this brings us back on the ground and not upon the sky. Additionally it means: we have to ´work harder on that and the WHO has to take responsibility: clinicians use a reponse classification without knowing, that this is just related to “ONE” experiment from the 70′s and that this experiment never had been rescrutinized (please read the Editorial I provided – we use a clinical response classification since more than 30 years worldwide (Miller et al. Cancer 1981) but it is useless !

  4. Dr. BB

    Thank you for your comment.
    Dr. Nir will reply to your comment.
    Regarding the Response Classification in use, it seems that the College of Oncology should champion a task force to revisit the Best Practice in use in this domain and issue a revised version or a new effort for a a new classification system for Clinical Response to treatment in Cancer.

  5. I’m sorry that I was looking for this paper again earlier and didn’t find it. I answered my view on your article earlier.

    This is a method demonstration, but not a proof of concept by any means. It adds to the cacophany of approaches, and in a much larger study would prove to be beneficial in treatment, but not a cure for serious prostate cancer because it is unlikely that it can get beyond the margin, and also because there is overtreatment at the cutoff of PSA at 4.0. There is now a proved prediction model that went to press some 4 months ago. I think that the pathologist has to see the tissue, and the standard in pathology now is for any result that is cancer, two pathologist or a group sitting together should see it. It’s not an easy diagnosis.

    ..Tumor heterogeneity is a ubiquitous phemomenon. In particular, there are important differences among the various types of gastrointestinal (GI) cancers in terms of tumor biology, treatment response and prognosis.

    ..This forms the principal basis for targeted therapy directed by tumor-specific testing at either the gene or protein level. Despite rapid advances in our understanding of targeted therapy for GI cancers, the impact on cancer survival has been marginal.

    ..Can tumor response to therapy be predicted, thereby improving the selection of patients for cancer treatment?

    ..In 2000 theNCI with the European Association for Research and Treatment of Cancer, proposed a replacement of 2D measurement with a decrease in the largest tumor diameter by 30% in one dimension. Tumor response as defined would translate into a 50% decrease for a spherical lesion

    ..We must rethink how we may better determine treatment response in a reliable, reproducible way that is aimed at individualizing the therapy of cancer patients.

    ..we must change the tools we use to assess tumor response. The new modality should be based on empirical evidence that translates into relevant and meaningful clinical outcome data.

    ..This becomes a conundrum of sorts in an era of ‘minimally invasive treatment’.

    ..integrated multidisciplinary panel of international experts – not sure that that will do it

    Several years ago i heard Stamey present the totality of his work at Stanford, with great disappointment over hsPSA that they pioneered in. The outcomes were disappointing.

    I had published a review of all of our cases reviewed for 1 year with Marguerite Pinto.
    There’s a reason that the physicians line up outside of her office for her opinion.
    The review showed that a PSA over 24 ng/ml is predictive of bone metastasis. Any result over 10 was as likely to be prostatitis, BPH or cancer.

    I did an ordinal regression in the next study with Gustave Davis using a bivariate ordinal regression to predict lymph node metastasis using the PSA and the Gleason score. It was better than any univariate model, but there was no followup.

    I reviewed a paper for Clin Biochemistry (Elsevier) on a new method for PSA, very different than what we are familiar with. It was the most elegant paper I have seen in the treatment of the data. The model could predict post procedural time to recurrence to 8 years.

    • I hope we are in agreement on the fact that imaging guided interventions are needed for better treatment outcome. The point I’m trying to make in this post is that people are investing in developing imaging guided intervention and it is making progress.

      Over diagnosis and over treatment is another issue altogether. I think that many of my other posts are dealing with that.

  6. Tumor response criteria: are they appropriate?
    Future Oncology 2012; 8(8): 903-906 , DOI 10.2217/fon.12.78 (doi:10.2217/fon.12.78)

    Tumor heterogeneity is a problematic because of differences among the metabolic variety among types of gastrointestinal (GI) cancers, confounding treatment response and prognosis.
    This is in response to … a group of investigators from Sunnybrook Health Sciences Centre, University of Toronto, Ontario, Canada who evaluate the feasibility and safety of magnetic resonance (MR) imaging–controlled transurethral ultrasound therapy for prostate cancer in humans. Their study’s objective was to prove that using real-time MRI guidance of HIFU treatment is possible and it guarantees that the location of ablated tissue indeed corresponds to the locations planned for treatment.
    1. There is a difference between expected response to esophageal or gastric neoplasms both biologically and in expected response, even given variability within a class. The expected time to recurrence is usually longer in the latter case, but the confounders are – age at time of discovery, biological time of detection, presence of lymph node and/or distant metastasis, microscopic vascular invasion.
    2. There is a long latent period in abdominal cancers before discovery, unless a lesion is found incidentally in surgery for another reason.
    3. The undeniable reality is that it is not difficult to identify the main lesion, but it is difficult to identify adjacent epithelium that is at risk (transitional or pretransitional). Pathologists have a very good idea about precancerous cervical neoplasia.

    The heterogeneity rests within each tumor and between the primary and metastatic sites, which is expected to be improved by targeted therapy directed by tumor-specific testing. Despite rapid advances in our understanding of targeted therapy for GI cancers, the impact on cancer survival has been marginal.

    The heterogeneity is a problem that will take at least another decade to unravel because of the number of signaling pathways and the crosstalk that is specifically at issue.

    I must refer back to the work of Frank Dixon, Herschel Sidransky, and others, who did much to develop a concept of neoplasia occurring in several stages – minimal deviation and fast growing. These have differences in growth rates, anaplasia, and biochemical. This resembles the multiple “hit” theory that is described in “systemic inflammatory” disease leading to a final stage, as in sepsis and septic shock.
    In 1920, Otto Warburg received the Nobel Prize for his work on respiration. He postulated that cancer cells become anaerobic compared with their normal counterpart that uses aerobic respiration to meet most energy needs. He attributed this to “mitochondrial dysfunction. In fact, we now think that in response to oxidative stress, the mitochondrion relies on the Lynen Cycle to make more cells and the major source of energy becomes glycolytic, which is at the expense of the lean body mass (muscle), which produces gluconeogenic precursors from muscle proteolysis (cancer cachexia). There is a loss of about 26 ATP ~Ps in the transition.
    The mitochondrial gene expression system includes the mitochondrial genome, mitochondrial ribosomes, and the transcription and translation machinery needed to regulate and conduct gene expression as well as mtDNA replication and repair. Machinery involved in energetics includes the enzymes of the Kreb’s citric acid or TCA (tricarboxylic acid) cycle, some of the enzymes involved in fatty acid catabolism (β-oxidation), and the proteins needed to help regulate these systems. The inner membrane is central to mitochondrial physiology and, as such, contains multiple protein systems of interest. These include the protein complexes involved in the electron transport component of oxidative phosphorylation and proteins involved in substrate and ion transport.
    Mitochondrial roles in, and effects on, cellular homeostasis extend far beyond the production of ATP, but the transformation of energy is central to most mitochondrial functions. Reducing equivalents are also used for anabolic reactions. The energy produced by mitochondria is most commonly thought of to come from the pyruvate that results from glycolysis, but it is important to keep in mind that the chemical energy contained in both fats and amino acids can also be converted into NADH and FADH2 through mitochondrial pathways. The major mechanism for harvesting energy from fats is β-oxidation; the major mechanism for harvesting energy from amino acids and pyruvate is the TCA cycle. Once the chemical energy has been transformed into NADH and FADH2 (also discovered by Warburg and the basis for a second Nobel nomination in 1934), these compounds are fed into the mitochondrial respiratory chain.
    The hydroxyl free radical is extremely reactive. It will react with most, if not all, compounds found in the living cell (including DNA, proteins, lipids and a host of small molecules). The hydroxyl free radical is so aggressive that it will react within 5 (or so) molecular diameters from its site of production. The damage caused by it, therefore, is very site specific. The reactions of the hydroxyl free radical can be classified as hydrogen abstraction, electron transfer, and addition.
    The formation of the hydroxyl free radical can be disastrous for living organisms. Unlike superoxide and hydrogen peroxide, which are mainly controlled enzymatically, the hydroxyl free radical is far too reactive to be restricted in such a way – it will even attack antioxidant enzymes. Instead, biological defenses have evolved that reduce the chance that the hydroxyl free radical will be produced and, as nothing is perfect, to repair damage.
    Currently, some endogenous markers are being proposed as useful measures of total “oxidative stress” e.g., 8-hydroxy-2’deoxyguanosine in urine. The ideal scavenger must be non-toxic, have limited or no biological activity, readily reach the site of hydroxyl free radical production (i.e., pass through barriers such as the blood-brain barrier), react rapidly with the free radical, be specific for this radical, and neither the scavenger nor its product(s) should undergo further metabolism.
    Nitric oxide has a single unpaired electron in its π*2p antibonding orbital and is therefore paramagnetic. This unpaired electron also weakens the overall bonding seen in diatomic nitrogen molecules so that the nitrogen and oxygen atoms are joined by only 2.5 bonds. The structure of nitric oxide is a resonance hybrid of two forms.
    In living organisms nitric oxide is produced enzymatically. Microbes can generate nitric oxide by the reduction of nitrite or oxidation of ammonia. In mammals nitric oxide is produced by stepwise oxidation of L-arginine catalyzed by nitric oxide synthase (NOS). Nitric oxide is formed from the guanidino nitrogen of the L-arginine in a reaction that consumes five electrons and requires flavin adenine dinucleotide (FAD), flavin mononucleotide (FMN) tetrahydrobiopterin (BH4), and iron protoporphyrin IX as cofactors. The primary product of NOS activity may be the nitroxyl anion that is then converted to nitric oxide by electron acceptors.
    The thiol-disulfide redox couple is very important to oxidative metabolism. GSH is a reducing cofactor for glutathione peroxidase, an antioxidant enzyme responsible for the destruction of hydrogen peroxide. Thiols and disulfides can readily undergo exchange reactions, forming mixed disulfides. Thiol-disulfide exchange is biologically very important. For example, GSH can react with protein cystine groups and influence the correct folding of proteins, and it GSH may play a direct role in cellular signaling through thiol-disulfide exchange reactions with membrane bound receptor proteins (e.g., the insulin receptor complex), transcription factors (e.g., nuclear factor κB), and regulatory proteins in cells. Conditions that alter the redox status of the cell can have important consequences on cellular function.
    So the complexity of life is not yet unraveled.

    Can tumor response to therapy be predicted, thereby improving the selection of patients for cancer treatment?
    The goal is not just complete response. Histopathological response seems to be related post-treatment histopathological assessment but it is not free from the challenge of accurately determining treatment response, as this method cannot delineate whether or not there are residual cancer cells. Functional imaging to assess metabolic response by 18-fluorodeoxyglucose PET also has its limits, as the results are impacted significantly by several variables:

    • tumor type
    • sizing
    • doubling time
    • anaplasia?
    • extent of tumor necrosis
    • type of antitumor therapy and the time when response was determined.
    The new modality should be based on individualized histopathology as well as tumor molecular, genetic and functional characteristics, and individual patients’ characteristics, a greater challenge in an era of ‘minimally invasive treatment’.
    This listing suggests that for every cancer the following data has to be collected (except doubling time). If there are five variables, the classification based on these alone would calculate to be very sizable based on Eugene Rypka’s feature extraction and classification. But looking forward, time to remission and disease free survival are additionally important. Treatment for cure is not the endpoint, but the best that can be done is to extend the time of survival to a realistic long term goal and retain a quality of life.

    • Dr. Larry,

      Thank you for this comment.

      Please carry it as a stand alone post, Dr. Ritu will refer to it and reference it in her FORTHCOMING pst on Tumor Response which will integrate multiple sources.

      Please execute my instruction

      Thank you

    • Thank you Larry for this educating comment. It explains very well why the Canadian investigators did not try to measure therapy response!

      What they have demonstrated is the technological feasibility of coupling a treatment device to an imaging device and use that in order to guide the treatment to the right place.

      the issue of “choice of treatment” to which you are referring is not in the scope of this publication.
      The point is: if one treatment modality can be guided, other can as well! This should encourage others, to try and develop imaging-based treatment guidance systems.

  7. The crux of the matter in terms of capability is that the cancer tissue, adjacent tissue, and the fibrous matrix are all in transition to the cancerous state. It is taught to resect leaving “free margin”, which is better aesthetically, and has had success in breast surgery. The dilemma is that the patient may return, but how soon?

    • Correct. The philosophy behind lumpectomy is preserving quality of life. It was Prof. Veronesi (IEO) who introduced this method 30 years ago noticing that in the majority of cases, the patient will die from something else before presenting recurrence of breast cancer..

      It is well established that when the resection margins are declared by a pathologist (as good as he/she could be) as “free of cancer”, the probability of recurrence is much lower than otherwise.

  8. Dr. Larry,

    To assist Dr. Ritu, PLEASE carry ALL your comments above into a stand alone post and ADD to it your comment on my post on MIS

    Thank you

  9. Great post! Dr. Nir, can the ultrasound be used in conjunction with PET scanning as well to determine a spatial and functional map of the tumor. With a disease like serous ovarian cancer we typically see an intraperitoneal carcimatosis and it appears that clinicians are wanting to use fluorogenic probes and fiberoptics to visualize the numerous nodules located within the cavity Also is the technique being used mainy for surgery or image guided radiotherapy or can you use this for detecting response to various chemotherapeutics including immunotherapy.

    • Ultrasound can and is actually used in conjunction with PET scanning in many cases. The choice of using ultrasound is always left to the practitioner! Being a non-invasive, low cost procedure makes the use of ultrasound a non-issue. The down-side is that because it is so easy to access and operate, nobody bothers to develop rigorous guidelines about using it and the benefits remains the property of individuals.

      In regards to the possibility of screening for ovarian cancer and characterising pelvic masses using ultrasound I can refer you to scientific work in which I was involved:

  10. totally true and i am very thankfull for these briliant comments.

    Remember: 10years ago: every cancer researcher stated: “look at the tumor cells only – forget the stroma”. The era of laser-captured tumor-cell dissection started. Now , everyone knows: it is a system we are looking at and viewing and analyzing tumor cells only is really not enough.

    So if we would be honest, we would have to declare, that all data, which had been produced 13-8years ago, dealing with laser capture microdissection, that al these data would need a re-scrutinization, cause the influence of the stroma was “forgotten”. I ‘d better not try thinking about the waisted millions of dollars.

    If we keep on being honest: the surgeon looks at the “free margin” in a kind of reductionable model, the pathologist is more the control instance. I personally see the pathologist as “the control instance” of surgical quality. Therefore, not the wish of the surgeon is important, the objective way of looking into problems or challenges. Can a pathologist always state, if a R0-resection had been performed ?

    The use of the Resectability Classification:
    There had been many many surrogate marker analysis – nothing new. BUT never a real substantial well tought through structured analysis had been done: mm by mm by mm by mm and afterwards analyzing that by a ROC analysis. BUt against which goldstandard ? If you perform statistically a ROC analysis – you need a golstandard to compare to. Therefore what is the real R0-resectiòn? It had been not proven. It just had been stated in this or that tumor entity that this or that margin with this margin free mm distance or that mm distance is enough and it had been declared as “the real R0-classification”. In some organs it is very very difficult and we all (surgeons, pathologists, clinicians) that we always get to the limit, if we try interpretating the R-classification within the 3rd dimension. Often it is just declared and stated.

    Otherwise: if lymph nodes are negative it does not mean, lymph nodes are really negative, cause up to 38% for example in upper GI cancers have histological negative lymph nodes, but immunohistochemical positive lymph nodes. And this had been also shown by Stojadinovic at el analyzing the ultrastaging in colorectal cancer. So the 4th dimension of cancer – the lymph nodes / the lymphatic vessel invasion are much more important than just a TNM classification, which unfortunately does often not reflect real tumor biology.

    AS we see: cancer has multifactorial reasons and it is necessary taking the challenge performing high sophisticated research by a multifactorial and multidisciplinary manner.

    Again my deep and heartly thanks for that productive and excellent discussion !

    • Dr. BB,

      Thank you for your comment.

      Multidisciplinary perspectives have illuminated the discussion on the pages of this Journal.

      Eager to review Dr. Ritu’s forthcoming paper – the topic has a life of its own and is embodied in your statement:

      “the 4th dimension of cancer – the lymph nodes / the lymphatic vessel invasion are much more important than just a TNM classification, which unfortunately does often not reflect real tumor biology.”

    • Thank you BB for your comment. You have touched the core limitation of healthcare professionals: how do we know that we know!

      Do we have a reference to each of the test we perform?

      Do we have objective and standardise quality measures?

      Do we see what is out-there or are we imagining?

      The good news: Everyday we can “think” that we learned something new. We should be happy with that, even if it is means that we learned that yesterday’s truth is not true any-more and even if we are likely to be wrong again…:)

      But still, in the last decades, lots of progress was made….

  11. Dr. Nir,
    I thoroughly enjoyed reading your post as well as the comments that your post has attracted. There were different points of view and each one has been supported with relevant examples in the literature. Here are my two cents on the discussion:
    The paper that you have discussed had the objective of finding out whether real-time MRI guidance of treatment was even possible and if yes, and also if the treatment could be performed in accurate location of the ROI? The data reveals they were pretty successful in accomplishing their objective and of course that gives hope to the imaging-based targeted therapies.
    Whether the ROI is defined properly and if it accounts for the real tumor cure, is a different question. Role of pathologists and the histological analysis they bring about to the table cannot be ruled out, and the absence of a defined line between the tumor and the stromal region in the vicinity is well documented. However, that cannot rule out the value and scope of imaging-based detection and targeted therapy. After all, it is seminal in guiding minimally invasive surgery. As another arm of personalized medicine-based cure for cancer, molecular biologists at MD Anderson have suggested molecular and genetic profiling of the tumor to determine genetic aberrations on the basis of which matched-therapy could be recommended to patients. When phase I trial was conducted, the results were obtained were encouraging and the survival rate was better in matched-therapy patients compared to unmatched patients. Therefore, everytime there is more to consider when treating a cancer patient and who knows a combination of views of oncologists, pathologists, molecular biologists, geneticists, surgeons would device improvised protocols for diagnosis and treatment. It is always going to be complicated and generalizations would never give an answer. Smart interpretations of therapies – imaging-based or others would always be required!

    Ritu

    • Dr. Nir,
      One of your earlier comments, mentioned the non invasiveness of ultrasound, thus, it’s prevalence in use for diagnosis.

      This may be true for other or all areas with the exception of Mammography screening. In this field, an ultrasound is performed only if a suspected area of calcification or a lump has been detected in the routine or patient-initiated request for ad hoc mammography secondery to patient complain of pain or patient report of suspected lump.

      Ultrasound in this field repserents ascalation and two radiologists review.

      It in routine use for Breast biopsy.

    • Thanks Ritu for this supporting comment. The worst enemy of finding solutions is doing nothing while using the excuse of looking for the “ultimate solution” . Personally, I believe in combining methods and improving clinical assessment based on information fusion. Being able to predict, and then timely track the response to treatment is a major issue that affects survival and costs!

Case Study #4:

  • Judging the ‘Tumor response’-there is more food for thought

  1. Dr. Sanexa
    you have brought up an interesting and very clinically relevant point: what is the best measurement of response and 2) how perspectives among oncologists and other professionals differ on this issues given their expertise in their respective subspecialties (immunologist versus oncologist. The advent of functional measurements of tumors (PET etc.) seems extremely important in the therapeutic use AND in the development of these types of compounds since usually a response presents (in cases of solid tumors) as either a lack of growth of the tumor or tumor shrinkage. Did the authors include an in-depth discussion of the rapidity of onset of resistance with these types of compounds?
    Thanks for the posting.

  2. Dr. Williams,
    Thanks for your comment on the post. The editorial brings to attention a view that although PET and other imaging methods provide vital information on tumor growth, shrinkage in response to a therapy, however, there are more aspects to consider including genetic and molecular characteristics of tumor.
    It was an editorial review and the authors did not include any in-depth discussion on the rapidity of onset of resistance with these types of compounds as the focus was primarily on interpreting tumor response.
    I am glad you found the contents of the write-up informative.
    Thanks again!
    Ritu

  3. Thank you for your wonderful comment and interpretation. Dr.Sanexa made a brilliant comment.

    May I allow myself putting my finger deeper into this wound ? Cancer patients deserve it.

    It had been already pointed out by international experts from Munich, Tokyo, Hong-Kong and Houston, dealing with upper GI cancer, that the actual response criteria are not appropriate and moreover: the clinical response criteria in use seem rather to function as an alibi, than helping to differentiate and / or discriminate tumor biology (Ann Surg Oncol 2009):

    http://www.ncbi.nlm.nih.gov/pubmed/19194759

    The response data in a phase-II-trial (one tumor entity, one histology, one treatment, one group) revealed: clinical response evaluation according to the WHO-criteria is not appropriate to determine response:

    http://www.ncbi.nlm.nih.gov/pubmed/15498642

    Of course, there was a time, when it seemed to be useful and this also has to be respected.

    There is another challenge: using statistically a ROC and resulting in thresholds. This was, is and always be “a clinical decision only” and not the decision of the statistician. The clinician tells the statistician, what decision, he wants to make – the responsibility is enormous. Getting back to the roots:
    After the main results of the Munich-group had been published 2001 (Ann Surg) and 2004 (J Clin Oncol):

    http://www.ncbi.nlm.nih.gov/pubmed/11224616

    the first reaction in the community was: to difficult, can’t be, not re-evaluated, etc.. However, all evaluated cut-offs / thresholds had been later proven to be the real and best ones by the MD Anderson Cancer Center in Houston, Texas. Jaffer Ajani – a great and critical oncologist – pushed that together with Steve Swisher and they found the same results. Than the upper GI stakeholders went an uncommon way in science: they re-scrutinized their findings. Meanwhile the Goldstandard using histopathology as the basis-criterion had been published in Cancer 2006.

    Not every author, who was at the authorlist in 2001 and 2004 wanted to be a part of this analysis and publication ! Why ? Everyone should judge that by himself.

    The data of this analysis had been submitted to the New England Journal of Medicine. In the 2nd review stage process, the manuscript was rejected. The Ann Surg Oncol accepted the publication: the re-scrutinized data resulted in another interesting finding: in the future maybe “one PET-scan” might be appropriate predicting the patient’s response.

    Where are we now ?

    The level of evidence using the response criteria is very low: Miller’s (Cancer 1981) publication belonged to ”one single” experiment from Moertel (Cancer 1976). During that time, there was no definition of “experiences” rather than “oncologists”. These terms had not been in use during that time.

    Additionally they resulted in a (scientifically weak) change of the classification, published by Therasse (J Natl Cancer Inst 2000). Targeted therapy did not result in a change so far. In 2009, the international upper GI experts sent their publication of the Ann Surg Oncol 2009 to the WHO but without any kind of reaction.

    Using molecular biological predictive markers within the last 10years all seem to have potential.

    But, experts are aware: the real step breaking barriers had not been performed so far. Additionally, it is very important in trying to evaluate and / predict response, that not different tumor entities with different survival and tumor biology are mixed together. Those data are from my perspective not helpful, but maybe that is my own Bias (!) of my view.

    INCORE, the International Consortium of Research Excellence of the Theodor-Billroth-Academy, was invited publishing the Editorial in Future Oncology 2012. The consortium pointed out, that living within an area of ‘prove of principle’ and also trying to work out level of evidence in medicine, it is “the duty and responsibility” of every clinician, but also of the societies and institutions, also of the WHO.

    Complete remission is not the only goal, as experts dealing with ‘response-research’ are aware. It is so frustrating for patients and clinicians: there is a rate of those patients with complete remission, who develop early recurrence ! This reflects, that complete remission cannot function as the only criterion describing response !

    Again, my heartly thanks, that Dr.Sanexa discussed this issue in detail.
    I hope, I found the way explaining the way of development and evaluating response criteria properly and in a differentiated way of view. From the perspective of INCORE:

    “an interdisciplinary initiative with all key stake¬holders and disciplines represented is imperative to make predictive and prognostic individualized tumor response assessment a modern-day reality. The integrated multidisciplinary panel of international experts need to define how to leverage existing data, tissue and testing platforms in order to predict individual patient treatment response and prognosis.”

  4. Dr. Brucher,

    First of all thanks for expressing your views on the ‘tumor response’ in a comprehensive way. You are the first author of the editorial review one of the prominent people who has taken part in the process of defining tumor response and I am glad that you decided to write a comment on the writeup.
    The topic has been explained well in an immaculate manner and that it further clarifies the need for the perfect markers that would be able to evaluate and predict tumor response. There are, as you mentioned, some molecular markers available including VEGF, cyclins, that have been brought to focus in the context of squamous cell carcinoma.

    It would be great if you could be the guest author for our blog and we could publish your opinion (comment on this blog post) as a separate post. Please let us know if it is OK with you.

    Thanks again for your comment
    Ritu

  5. Thank you all to the compelling discussions, above.

    Please review the two sources on the topic I placed at the bottom of the post, above as post on this Scientific Journal,

    All comments made to both entries are part of thisvdiscussion, I am referring to Dr. Nir’s post on size of tumor, to BB comment to Nir’s post, to Larry’ Pathologist view on Tumors and my post on remission and minimally invasive surgery (MIS).

    Great comments by Dr. Williams, BB and wonderful topic exposition by Dr. Ritu.

  6. Aviva,
    Thats a great idea. I will combine all sources referred by you, the post on tumor imaging by Dr. Nir and the comments made on the these posts including Dr. Brucher’s comments in a new posts.
    Thanks
    Ritu

    • Great idea, ask Larry, he has written two very long important comments on this topic, one on Nir’s post and another one, ask him where, if it is not on MIS post. GREAT work, Ritu, integration is very important. Dr, Williams is one of our Gems.

    • Assessing tumour response it is not an easy task!Because tumours don’t change,but happilly our knowlege(about them) does really change,is everchanging(thans god!).In the past we had the Recist Criteria,then the Modified Recist Criteria,becausa of Gist and other tumors.At this very moment,these are clearly insuficient.We do need more new validated facing the reality of nowadays. A great, enormoust post Dr. Ritu! Congratulations!

 

Conclusions

The Voice of Aviva Lev-Ari, PhD, RN:

The relevance of the Scientific Agora to Medical Education is vast. The Open Access Journal allows EVERY Scientist on the internet the GLOBAL reach and access to Open Access published scientific contents NOT only to the subscription payer base of Journals. If you don’t have a HIGH FEE subscription you get NO access to content in the Journal, you can’t participate in Multiple Comment Exchanges. In the Medical Education context – COMMENTS are the medium to debate with peers. 

Multiple Comment Exchanges on Four articles in the Journal, above, demonstrate the vibrancy of the scientific discussion, the multiplicity of perspectives, the subjectivity of the contribution to the debate and the unique expertise and clinical experience expressed by each Scientist.
