Mutational analysis and clinical correlation of 185 consecutive metastatic colorectal patients: Similarities and differences between colon and rectal patients| 2011 ASCO Abstract
Conclusions:
Rectal and colon patients have similar rates of KRAS and PIK3CA mutations. However, BRAF mutations are more common in colon cancer. NRAS mutations are exclusively found in rectosigmoid cancers and may have a different biology than other colorectal cancers. These data suggest that primary tumor location may provide a means to enrich a population for a genotype-directed study.

University of Pennsylvania School of Medicine - Women with BRCA mutations can take hormone-replacement therapy safely after ovary removal
CHICAGO) ––
Women with the BRCA1 or BRCA2 gene mutations, which are linked to a very high risk of breast and ovarian cancer, can safely take hormone-replacement therapy (HRT) to mitigate menopausal symptoms after surgical removal of their ovaries, according to new research from the Perelman School of Medicine at the University of Pennsylvania which will be presented Monday, June 6 during the American Society for Clinical Oncology's annual meeting (Abstract #1501). Results of the prospective study indicated that women with BRCA mutations who had their ovaries removed and took short-term HRT had a decrease in the risk of developing breast cancer...............
Domchek says some of the confusion about the role of HRT in cancer risk elevation comes from the fact that the risks and benefits associated with HRT depend on the population of women studied. In this group of women – who have BRCA1/2 mutations and who have had their ovaries removed while they are quite young – HRT should be discussed and considered an option for treating menopausal symptoms. "People want to make hormone replacement therapy evil, so they can say 'Don't do it,'" she says. "But there isn't one simple answer. The devil is in the details of the studies."
By contrast, Penn researchers and their collaborators in the PROSE consortium have shown definitively that oophorectomy reduces ovarian and breast cancer incidence in these women, and reduces their mortality due to those cancers. But paying attention to the role that hormone depletion following preventive oophorectomy plays in women's future health (blogger's note: eg. cardiovascular) is also important............"

Medical News: Group Issues Gyn Cancer Follow-Up Guidance - MedPage Today
For ovarian (epithelial) cancer, the committee recommended:
- Physical exam and review of symptoms: Every three months for two years, followed by increasing intervals
- Pap test: Not indicated
- CA-125: Optional
- Radiographic imaging: Insufficient data to support routine use
- Suspected recurrence: CT and/or PET, plus CA-125
- Physical exam and review of symptoms: Every two to four months for two years, then every six months or annually depending on histology
- Serum tumor markers: Every two to four months for two years, then every six months for sex-cord stromal tumors but no longer indicated for germ-cell tumors
- Radiographic imaging: Generally, not indicated or data lacking to support routine use
- Suspected recurrence: CT and tumor markers
Moreover, a survey of primary care providers showed that respondents believed transition of oncology patients could be improved with individualized patient summaries, guidelines for surveillance, and expedited referral for suspected recurrence, the committee members noted.
"Thus, the provision of up-to-date information and the education of both patients and physicians are mandatory," they wrote.
"Action Points
Point out that this report indicates that there is very little evidence that either routine cytologic procedures or imaging are sufficiently useful to detect ovarian and endometrial cancer recurrence and alter response rates to salvage therapy.
Note that this report suggests that the most effective method to detect recurrences is a taking a thorough history, performing a detailed physical examination, and educating patients about relevant symptoms."

press release - UK - Targeted testing offers treatment hope for ovarian cancer patients
Public release date: 30-May-2011
Targeted testing offers treatment hope for ovarian cancer patients
Women with ovarian cancer could be helped by a new test that identifies the specific type of tumour they have, a conference will hear this week.
Researchers at the University of Edinburgh hope this improved diagnosis will help doctors to personalise treatment programmes so that patients receive the most effective drugs.
The Edinburgh team worked with scientists from Ireland to identify six subgroups of the disease, each of which had a different genetic signature.
To do this, they analysed tissue samples from more than 350 ovarian cancer patients and compared this information with the patients' medical records.
The results show how genetic profiling of ovarian cancers might predict a person's response to drug treatments.
Researchers say the development may be particularly helpful for women with an aggressive form of ovarian cancer, which is typically caught late by current diagnostic tests.
This type of aggressive – or 'high grade' – cancer can respond well to a recently-developed drug that targets the blood supply of the cancer cells. (blogger's note - it is not clear from this press release if this is specific to serous cell type)
The team hopes that by identifying the women with this type of cancer at the earliest opportunity, they could use the drug more effectively and help to improve survival rates.
The findings will be presented at the American Society of Clinical Oncology (ASCO) conference, being held in Chicago this week.
Dr Charlie Gourley of the University of Edinburgh, who led the study, said: "This research shows that by conducting a detailed analysis of the genes of ovarian cancers we may be able to identify those patients who will respond well to new drug treatments. This could bring valuable improvements in survival rates for the disease and would help us to personalise a patient's care to ensure the greatest possible success."
Ovarian cancer is the fifth most common cancer in women, with around 6,800 women being diagnosed every year in the UK.
Of these, nearly two-thirds will not live beyond five years of their diagnosis.
Chemotherapy and surgery can be effective treatments, but women could have a greater chance of surviving the disease if it is identified earlier on.
The findings will be presented at ASCO on Saturday 4th June.

Expert Opinion: The Therapeutic Target Database: an Internet resource for the primary targets of approved, clinical trial and experimental drugs
Note: the full article is pay-per-view ($$$)
".....Increasing numbers of proteins, nucleic acids and other molecular entities have been explored as therapeutic targets.
A challenge in drug discovery is to decide which targets to pursue from an increasing pool of potential targets, given the fact that few innovative targets have made it to the approval list each year.

Evidence Updates including professional commentaries: Safety of Probiotics to Reduce Risk and Prevent or Treat Disease.
"....Existing studies primarily examined Lactobacillus alone or in combination with other genera, often Bifidobacterium.
Few studies directly compared the safety among different intervention or participant characteristics. Indirect comparisons indicated that effects of delivery vehicles (e.g., yogurt, dairy) should be investigated further.
Case studies suggested that participants with compromised health are most likely to experience adverse events associated with probiotics. However, RCTs in medium-risk and critically ill participants did not report a statistically significantly increased risk of adverse events compared to control group participants.
Conclusions. There is a lack of assessment and systematic reporting of adverse events in probiotic intervention studies, and interventions are poorly documented. The available evidence in RCTs does not indicate an increased risk; however, rare adverse events are difficult to assess, and despite the substantial number of publications, the current literature is not well equipped to answer questions on the safety of probiotic interventions with confidence."
Evidence Updates including professional commentaries - : Acupuncture: does it alleviate pain and are there serious risks? A review of reviews.
Acupuncture is commonly used for pain control, but doubts about its effectiveness and safety remain.
This review was aimed at critically evaluating systematic reviews of acupuncture as a treatment of pain and at summarizing reports of serious adverse effects published since 2000. Literature searches were carried out in 11 databases without language restrictions. Systematic reviews were considered for the evaluation of effectiveness and case series or case reports for summarizing adverse events. Data were extracted according to predefined criteria. Fifty-seven systematic reviews met the inclusion criteria. Four were of excellent methodological quality. Numerous contradictions and caveats emerged. Unanimously positive conclusions from more than one high-quality systematic review existed only for neck pain. Ninety-five cases of severe adverse effects including 5 fatalities were included. Pneumothorax and infections were the most frequently reported adverse effects.
In conclusion, numerous systematic reviews have generated little truly convincing evidence that acupuncture is effective in reducing pain. Serious adverse effects continue to be reported. Numerous reviews have produced little convincing evidence that acupuncture is effective in reducing pain.
Serious adverse events, including deaths, continue to be reported.
EvidenceUpdates + professional commentaries (numerous): Calcium supplements with or without vitamin D and risk of cardiovascular events: reanalysis of the Women`s Health Initiative limited access dataset and meta-analysis
OBJECTIVES: To investigate the effects of personal calcium supplement use on cardiovascular risk in the Women`s Health Initiative Calcium/Vitamin D Supplementation Study (WHI CaD Study), using the WHI dataset, and to update the recent meta-analysis of calcium supplements and cardiovascular risk.
DESIGN: Reanalysis of WHI CaD Study limited access dataset and incorporation in meta-analysis with eight other studies.........
Conclusions: Calcium supplements with or without vitamin D modestly increase the risk of cardiovascular events, especially myocardial infarction, a finding obscured in the WHI CaD Study by the widespread use of personal calcium supplements. A reassessment of the role of calcium supplements in osteoporosis management is warranted.

abstract: Mucinous carcinomas of the ovary and colorectum: different organ, same dilemma : The Lancet Oncology
Mucinous carcinomas of the ovary and colorectum: different organ, same dilemma
Dr Linda E Kelemen ScD a d 
,
, Summary
Mucinous
carcinomas are uncommon histological types that affect several organ
sites.
Primary mucinous carcinomas of the ovary are distinct from other
ovarian carcinoma types, but they can pose a particular challenge for
correct diagnosis from metastases, which most usually originate from the
colorectum.
Correct diagnosis is the mainstay of treatment, because
standard practice states that protocols are tailored to the primary
organ site. Little is known of mutational alterations in primary and
metastatic mucinous carcinomas of the ovary, and few markers exist that
can discriminate between them.
We reviewed commonalities between ovarian
and colorectal mucinous carcinomas with respect to aetiology, molecular
alterations, differential diagnosis, and implications for treatment.
Although primary mucinous carcinomas of the ovary and colorectum share
similar mutational patterns and unfavourable outcomes at advanced stage,
compared with their non-mucinous counterparts, important differences
exist with respect to mucin localisation and specific molecular
alterations.
Technologies—eg, next-generation sequencing—could aid
identification of additional driver molecular changes that will help
clarify the relation between mucinous carcinomas from different organ
sites. Perhaps, then, we can consider moving towards testing and
adoption of therapeutic approaches tailored to molecular characteristics
of mucinous carcinomas, irrespective of organ site, so patients'
survival can be optimised.
abstract: Mitochondrial DNA genotyping reveals synchronous nature of simultaneously detected endometrial and ovarian cancers.
Abstract
Simultaneous independent primary tumors of the female genital tract occur in 1-2% of gynecological cancer patients, 50-70% of which are synchronous tumors of the endometrium and ovary.Guidelines for determining the nature of simultaneously detected tumors, based on surgical and histopathological findings, are often ambiguous and may require further molecular analyses.
Such approach is necessary to indicate correct prognosis and hence treatment.
We here demonstrate how mitochondrial DNA sequencing may provide a cheap and useful tool to contribute to indisputably recognize the synchronous nature of simultaneously detected endometrial and ovarian carcinomas. We further confirm our findings by means of Comparative Genomic Hybridization array analysis, which strengthens the informative potential of mitochondrial DNA genotyping in diagnosing synchrony.
abstract: Effects of bevacizumab and pegylated liposomal doxorubicin for the patients with recurrent or refractory ovarian cancers
OBJECTIVES:
Currently, pegylated liposomal doxorubicin (PLD) is regarded as one of the standard treatment options in recurrent ovarian cancers (ROC). Bevacizumab has shown significant antitumor activity for ROC in single-agent or in combination with cytotoxic agents. We have conducted a preliminary study to investigate effects of combination of bevacizumab and PLD for heavily pretreated patients with ROC.
CONCLUSION:
The present investigation suggested that combination therapy with bevacizumab and PLD was active and well tolerated for patients with ROC. We recommend the regimen be evaluated in further clinical studies.
abstract: Cost-effectiveness of combination versus sequential docetaxel and carboplatin for the treatment of platinum-sensitive, recurrent ovarian cancer
CONCLUSIONS:
Combined weekly cDC (concurrent docetaxel and carboplatin) appeared to
be cost-effective compared with sDC (sequential docetaxel and carboplatin ) as treatment strategy for patients
with platinum-sensitive ovarian cancer, even when accounting for
slightly lower QoL during treatment.
abstract: Feasibility of a lifestyle intervention for ovarian cancer patients receiving adjuvant chemotherapy
OBJECTIVES
This study aimed to assess the feasibility of a lifestyle intervention for promoting physical activity (PA) and diet quality during adjuvant chemotherapy for ovarian cancer.METHODS:
Patients were enrolled post-operatively and received PA and nutrition counseling, at every chemotherapy visit for six cycles. Quality of life (QoL) was measured with the Functional Assessment of Cancer Therapy (FACT-G), PA with the Leisure Score Index (LSI), dietary intake with 3-day food records, and symptom severity/distress by the Memorial Symptom Assessment Scale (MSAS). Pedometer step count was collected during chemotherapy cycles.RESULTS:
Recruitment was 73% with 27 patients enrolled. Mean [95% confidence interval] change in minutes of PA from cycle #3 to following cycle #6 was 61min [-3, 120] p=0.063, and from baseline to after cycle #6 was 73min [-10, 15]; p=0.082. Mean change in total fruit and vegetable consumption between baseline and during chemotherapy was 0.56 [-0.09, 0.64]; p=0.090. FACT-G increased from 75.4 at baseline to 77.6 during chemotherapy and 83.9 following chemotherapy (p=0.001 for change from baseline to post-chemotherapy).Mean total MSAS ( Memorial Symptom Assessment Scale) score was 20.6 at baseline, 26.6 at cycle #3 and decreased to 17.0 following chemotherapy (p=0.01 comparison of cycle #3 and following chemotherapy). Increased moderate to strenuous PA was correlated with higher physical well-being during chemotherapy (r=0.48, p=0.037).
CONCLUSIONS:
Lifestyle counseling during adjuvant chemotherapy for ovarian cancer is feasible and may improve PA and diet quality. Randomized controlled trials examining the effects of lifestyle counseling on quality of life and treatment outcomes in ovarian cancer patients are warranted.Editorial - no abstract/pay-per-view: - Gynecologic Oncology : More than a biomarker: CA125 may contribute to ovarian cancer pathogenesis

abstract: Pyridoxine (Vitamin B6) to protect from oxaliplatin-induced neurotoxicity without compromising antitumour effect
CONCLUSIONS:
Administration of pyridoxine (Vitamin B6) , at concentrations extending across possible therapeutic plasma levels in humans, does not antagonise OHP (Oxaliplatin) antitumour effects in a range of relevant tumour cell lines.
This study provides a foundation for clinical studies to test whether pyridoxine can minimise OHP-related neurotoxicity, and clinicians can be confident that pyridoxine is very unlikely to reverse the antitumour effects of OHP, as seems to be the case with Ca/Mg infusions.
This could prove to be a cost-effective way to minimise OHP-related neurotoxicity, allowing more effective less toxic treatment and better outcomes in patients.
abstract: Reducing Time to Diagnosis Does Not Improve Outcomes for Women With Symptomatic Ovarian Cancer: A Report From the Australian Ovarian Cancer Study Group

Patients' power and PACE : The Lancet - Editorial (not specfic to ovarian cancer)
"...Once every few years, we publish a paper that elicits an outpouring of consternation and condemnation from individuals or groups outside our usual reach. The latest topic to have caused such a reaction is chronic fatigue syndrome (CFS), and—more specifically—Peter White and colleagues' randomised PACE trial published on March 5, this year....The response to the trial's publication was swift and damning. “When is the Lancet going to retract this fraudulent study?” demanded a Facebook group. A 43-page complaint (now available via Wikipedia) branded the trial “unethical and unscientific”. There were 44 formal letter submissions, eight of which we publish today, together with a response from White and colleagues." cont'd

MSH6 - Defects in MSH6 are the cause of (Lynch Syndrome) hereditary non-polyposis colorectal cancer type 5 (HNPCDNA mismatch repair protein Msh6 - Homo sapiens (Human)
Defects in MSH6 are the cause of hereditary non-polyposis colorectal cancer type 5 (HNPCC5) [MIM:600678]. Mutations in more than one gene locus can be involved alone or in combination in the production of the HNPCC phenotype (also called Lynch syndrome). Most families with clinically recognized HNPCC have mutations in either MLH1 or MSH2 genes. HNPCC is an autosomal, dominantly inherited disease associated with marked increase in cancer susceptibility. It is characterized by a familial predisposition to early onset colorectal carcinoma (CRC) and extra-colonic cancers of the gastrointestinal, urological and female reproductive tracts. HNPCC is reported to be the most common form of inherited colorectal cancer in the Western world. Cancers in HNPCC originate within benign neoplastic polyps termed adenomas.
Clinically, HNPCC is often divided into two subgroups. Type I: hereditary predisposition to colorectal cancer, a young age of onset, and carcinoma observed in the proximal colon. Type II: patients have an increased risk for cancers in certain tissues such as the uterus, ovary, breast, stomach, small intestine, skin, and larynx in addition to the colon. Diagnosis of classical HNPCC is based on the Amsterdam criteria: 3 or more relatives affected by colorectal cancer, one a first degree relative of the other two; 2 or more generation affected; 1 or more colorectal cancers presenting before 50 years of age; exclusion of hereditary polyposis syndromes.
MSH6 mutations appear to be associated with atypical HNPCC and in particular with development of endometrial carcinoma or atypical endometrial hyperplasia, the presumed precursor of endometrial cancer. Defects in MSH6 are also found in familial colorectal cancers (suspected or incomplete HNPCC) that do not fulfill the Amsterdam criteria for HNPCC. Ref.17 Ref.31 Ref.33 Ref.38 Ref.41 Ref.45 Ref.46
U.S. news writer requests interviews: re: drug shortages cancer patients
From: <acarrns@aol.com>
Date: Wed, May 25, 2011 at 3:05 PM
I'm a freelance writer.. This year's topic is the impact of ongoing drug shortages, and I'm seeking to interview a patient or two (or their family) who has been affected by this. Some cancer patients, for example, are having trouble getting a drug called cytarbarine, and there are a host of others in shortage too. Would you have any suggestions for reaching such patients? of course am trying to do this as soon as possible, in next week or so.

“There are now dozens of studies that demonstrate superior patient outcomes with restrictive transfusion practices,” Dr. Ereth said. “In general, the less blood you transfuse, the better your patient outcomes. In the future we will hopefully be able to further define the mechanisms of immune modulation with transfusion and then when transfusion is absolutely necessary, be able to design interventions to limit those effects.”
Until then, however, he stressed that efforts should be made in all clinical settings to minimize blood transfusion as much as possible.

"I wonder if you can help me with some 'consumer input' into the use of stents ch stoma and no intervention eg relief with stents, for how long, eating and energy, and harmful effects
I am trying to do a response to a health technology assessment - for introduction of the stents.
I can talk about the trauma of partial and complete
blockages in the late stages of cancer, but not specifically stents
If you have the time to jot down a few points that
would be really appreciated."
abstract: Radiation-Induced Micro-RNA Expression Changes in Peripheral Blood Cells of Radiotherapy Patients
Conclusions
Exposure to ionizing radiation leads to the upregulation of the expression of a considerable proportion of the human miRNAome of peripheral blood cells. These miRNA expression signatures can be used as biomarkers of radiation exposure.OVA1 Improves Ovarian Cancer Detection Over CA 125 Blood Test and Clinical Assessment - press release - 2nd study
Second study in Obstetrics & Gynecology showcases OVA1's role in evaluating women with an ovarian mass
"In the manuscript "Effectiveness of a Multivariate Index Assay in the Preoperative Assessment of Ovarian Tumors," physician assessment and the use of OVA1 correctly identified 70% of malignancies missed by physician assessment among gynecologists and other non-gynecologic oncologists, and 95% of malignancies missed by physician assessment among gynecologic oncologists. OVA1 also detected 76% of malignancies that would have been missed by CA 125 using ACOG-recommended guidelines......"

Science blogger deflates sensationalism of "Scientists cure cancer, but no one takes notice" story - Gary Schwitzer's HealthNewsReview Blog
"....So we have one popular account that is badly written and makes exaggerated claims. There is also a university press release, the source for the sloppy popular account, that doesn't contain the egregious stupidities but does tend to inflate basic research studies into an unwarranted clinical significance. And then, of course, there are the actual peer reviewed papers that describe the research and rationale, and also the reservations, on DCA. It's like a game of telephone: you can actually trace the account from the sober science paper to the enthusiastic press release to the web account with its extravagant claims of a simple, cheap cure for cancer, and see how the story is gradually corrupted. It would be funny if the final result wasn't going to dupe a lot of desperate people.
But there is a germ of truth to the story, in that DCA does have potential.
...
We should be urging further investigation of this promising drug with the beginning of clinical trials, but it's far too early to be babbling about "cancer cures". There have been lots of drugs that look great in the lab and have excellent rationales for why they should work, but the reality of cancer is that it is complicated and diverse and there are many more pitfalls between a drug that poisons cancer cells in a petri dish and a drug that actually works well in the more complex environment of a human being."
Predicting longevity and curing cancer — quackery, or mere exaggeration? > Facts & Fears > ACSH (re: DCA)
.....In another example of scientific distortion at least bordering on quackery that has infiltrated the media, a Fox News LiveScience blog chastises big pharma for their alleged reluctance to engage in cancer research involving a chemical known as dichloroacetate (DCA), due to their inability to patent it, thereby eliminating the profit motive. The piece chronicles the work of Dr. Evangelos Michelakis, a cancer researcher at the University of Alberta, whose claims that DCA can kill cancer cells are based solely on test tube experiments, animal testing and an extremely small clinical trial he conducted, which was composed of only five patients. Though even he admitted that “with the small number of treated participants in our study, no firm conclusions regarding DCA as a therapy…can be made,” he still attacks pharmaceutical companies for not investing in further research.
But not so fast. As Gary Schwitzer points out on his site, healthnewsreview.org, wherein he links to another blogger’s exposé of the DCA-conspiracy theory, the claims regarding DCA as an effective cancer treatment have been largely exaggerated: since there have been no clinical trials using the chemical, there is no basis for the researchers to allude to a cure.
And even if the claims were true, pharmaceutical companies actually could obtain protection via a “use patent.” This permits patent protection for old products (or drugs) where a new use has been discovered, explains ACSH’s Dr. Josh Bloom. “So this whole story is chock full of misinformation," he observes. "What is more likely is that Dr. Michelakis approached drug companies and they were just not interested.”...."
media: Is Big Pharma Ignoring a Potential Cancer Cure? - FoxNews.com (DCA/University of Alberta)
"......A new drug model
Small trials and case studies won't be enough, however, to prove DCA works. Further investigation into the drug's efficacy is necessary, and without the help of Big Pharma, it will have to happen in an unusual way.
"This could be a social experiment where the public funds these trials," Michelakis said. "After discovering the effect of DCA on cancer cells, I consider this the second-biggest achievement of our work: when we showed that you can bring a drug to human trials without a lot of money. If others were inspired" — his group is beginning to establish collaborations with some prominent cancer hospitals —"this could be a major achievement. Eventually the federal bodies like the National Cancer Institute would see there is enough evidence, and then they'll help with funding."
"It represents a new attitude and a new way of thinking," he added......"
