clinical trial: Primary Tumor Harvest for the Purpose of Possible Use in a Future Clinical Trial in Patients With Ovarian, Fallopian Tube or Primary Peritoneal Cancer
The aim of this study is to determine the frequency of the three most common BRCA1 and BRCA2 genetic mutations that are commonly found in Ashkenazi Jewish patients with pancreatic cancer. Testing for BRCA1 and BRCA2 mutations in relatives of hereditary pancreatic cancer patients may have a significant impact; allowing for early screening, treatment, and resection of pre-malignant tissue or malignant lesions.

"It seems astonishing that in the 21st century decisions on health care can still be made without a solid grounding in research evidence. This is true even in clinical research, whether for simple or complex interventions , where systematic reviews time and time again conclude that the evidence base is inadequate . It is even more true in the areas of health policy and health systems, where quality research is hampered further by a lack of shared definitions, a lack of consensus on guiding principles, poor capacity (especially in low-resource regions), and methodological challenges ,.
The World Health Report (WHR) for 2012 will be on the theme of “No Health without Research”. This flagship report from WHO will, for the first time in its history, focus on research for better health. The primary target audience of the report will be ministers of health in the WHO member states, and the goal of the report is to provide new ideas, innovative thinking, and pragmatic advice for member states on how to strengthen their own health research systems. The report will have the three following aims.
- To show that research is important for meeting health needs and improving health outcomes;
- To encourage countries to therefore invest more resources in developing and strengthening their national health research systems;
- To argue that countries should not see research as an expense or as an afterthought, but as an investment for a better, healthier future.....cont'd

Association Between a Name Change from Palliative to Supportive Care and the Timing of Patient Referrals -- The Oncologist
"....Because of the nature of our institution as a comprehensive cancer center
with a large patient volume, the results might not be generalizable to smaller cancer centers and oncology programs in other areas. However, the findings
of our study regarding a higher overall number of referrals and earlier
referrals in the outpatient setting confirm the findings of our previous
survey study on the attitudes and beliefs of medical oncologists and
midlevel providers regarding the term palliative care. We believe
that these findings and the difference in referral pattern after the
name change are not center specific but rather reflect perceptions
among health care professionals in the U.S. regarding the strong
associations among palliative care, hospice, and end of life."
Conclusion The name change to supportive care was associated with more inpatient referrals and earlier referrals in the outpatient setting. The outpatient setting facilitates earlier access to supportive/palliative care and should be established in more centers.
Of interest: note reference to organ transplant (not new news but under-recognized??)
In the cancer clinic, physicians and other oncology caregivers are
occasionally asked whether cancer can ever be passed along from
one individual to another. One example is the wife who asks whether
she could ever "catch" cancer from her husband with prostate cancer.
Although the answer to that one is no, the question of a man "catching"
cancer from a partner with cervical cancer is not unrealistic since
various strains of human papilloma virus are known causes of cervical
cancer as well as penile cancer. Pathogens including certain viruses,
bacteria, and parasites represent major causes of cancer in developing
parts of the world. In fact, an estimated 1.5 million cases per year or
15% of all cancers worldwide can be attributed to infectious
etiologies, mostly due to viral infections...."cont'd

For Medical ProfessionalsBecause ovarian cancer has no screening tools, blood tests and the symptoms
often are mistaken for other conditions, misdiagnosed and even ignored OCATS has developed an OCATS Physician Guide (available to anyone). This guide
was developed to help medical professionals and women recognize the
symptoms, be aware of symptoms andcombinations of symptoms, the diagnostic tools available to every physician, proper referral practices for women
with the possibility of a gynecologic cancer. We will soon be sending this
guide to every medical clinic and medical
professional in Saskatchewan.

abstract: Low-dose abdominal radiation as a docetaxel chemosensitizer for recurrent epithelial ovarian cancer: A phase I study GOG
ObjectivePatient surveillance after potentially curative treatment of ovarian carcinoma has important clinical and financial implications for patients and society. The optimal intensity of surveillance for these patients is unknown. We aimed to document the current follow-up practice patterns of gynecologic oncologists.
MethodsWe created four idealized vignettes describing patients with stages I–III ovarian cancer. We mailed a custom-designed survey instrument based on the vignettes to the members of the Society of Gynecologic Oncologists (SGO). SGO members were asked, via this instrument, how often they requested 11 discrete follow-up evaluations for their patients for the first 10 postoperative years after treatment with curative intent.
ResultsWe received 283 evaluable responses (30%) from the 943 SGO members and candidate members. The most frequently performed items for each year were office visit, pelvic examination, and serum CA-125 level. Imaging studies such as chest X-ray, abdominal–pelvic CT, chest CT, abdominal–pelvic MRI, and transvaginal ultrasound were rarely recommended. There was marked variation in the frequency of use of most tests. There was a decrease in the frequency of testing over time for all modalities.
ConclusionThis dataset provides detailed documentation of the self-reported surveillance practices of highly credentialed experts who manage patients with ovarian cancer in the 21st century. The optimal follow-up strategy remains unknown and controversial. Our survey showed marked variation in surveillance intensity. Identifying the sources of this variation warrants further research.

These complaints contain detailed narratives about the case, and these data can be used to understand which factors contribute to errors in health care .
The purpose of this study was to evaluate the nature of preventable ADEs based on data from national supervisory authority. In particular, the study focuses on the potential causes and contributing factors of preventable ADEs from the information management point of view.
The study aims to answer the following questions:
1. What are the causes of ADEs, and in which phase of the medication management process are the causes for ADEs present?
2. How does information management affect the origin of ADEs?
3. What are the contributing factors for ADEs in information management?

BackgroundHereditary nonpolyposis colorectal cancer (HNPCC), an autosomal-dominant syndrome, accounts for 2-5% of all colorectal carcinomas. Colorectal cancer in patients with hereditary nonpolyposis colorectal cancer (HNPCC) presents at an earlier age than in the general population and is characterized by an increased risk of other cancers, such as endometrial cancer and, to a lesser extent, cancers of the ovary, stomach, small intestine, hepatobiliary tract, pancreas, upper urinary tract, prostrate, brain, and skin.
Table 1. Seven different genes are known to be associated with HNPCC,

"The overall outlook for the routine assessment of patient-reported outcomes in clinical trials is assured and, eventually, it is likely to become a standard part of clinical practice. However, there is still a need for a clear method for determining the clinical meaningfulness of changes in scores. The answer will probably come from the greater use of patient-reported outcomes and the consequent growth of experience that is necessary to make such judgements"

Tuesday, January 18, 2011
"The results indicate that HBOC and HNPCC (Lynch Syndrome) associated ovarian cancer develop along distinct genetic pathways and genetic profiles can thus be applied to distinguish between different types of hereditary ovarian cancer."
Familial breast, prostate, and colorectal cancers might have a yet unidentified genetic component associated with poorer survival. It may be useful to record survival data in family history records.
METHODS: We conducted a review of patients with recurrent epithelial ovarian carcinoma treated with bevacizumab between 2006 and 2009. Demographic and treatment data were collected for statistical analysis.
RESULTS: Eighty-two patients were identified; perforation occurred in 8 (9.76%). Among patients with perforation, a significantly higher incidence of prior bowel surgeries (p=0.0008) and prior bowel obstruction or ileus.
CONCLUSIONS: Predicting BAP remains a challenge. Bowel obstruction or ileus appears to be associated with increased risk of BAP.
Inequity in access to cancer care: a review of the Canadian literature.
AbstractDespite the policy and research attention on ensuring equitable access-equal access for equal need-to health care, research continues to identify inequities in access to cancer services. We conducted a literature review to identify the current state of knowledge about inequity in access to cancer health services in Canada in terms of the continuum of care, disease sites, and dimensions of inequity (e.g., income). We searched MEDLINE, CINAHL, and Embase for studies published between 1990 and 2009. We retrieved 51 studies, which examine inequity in access to cancer services from screening to end-of-life care, for multiple cancer types, and a variety of socioeconomic, geographic, and demographic factors that may cause concern for inequity in Canada. This review demonstrates that income has the most consistent influence on inequity in access to screening, while age and geography are most influential for treatment services and end-of-life care, even after adjusting for patient need. Our review also reports on methods used in the literature and new techniques to explore. Equitable access to cancer care is vitally important in all health systems. Obtaining information on the current status of inequities in access to cancer care is a critical first step toward action.
full free access: Absence of microsatellite instability in mucinous carcinomas of the breast (Lynch Syndrome)
Note: some key excerpt; see also Supplemental Tables 1-4
"Microsatellite instability (MSI) is a form of genetic instability that results from defects in DNA mismatch repair. MSI is reported to be rare in unselected breast cancers, however it is a common feature in subsets of colorectal, ovarian and endometrial cancers. In these anatomical sites, MSI-high carcinomas often display a mucinous histology. The aim of this study was to determine whether mucinous carcinomas of the breast would more frequently display MSI-high than invasive ductal carcinomas of no special type (IDC-NSTs). The expression of four MSI markers (i.e. MSH2, MSH6, MLH1 and PMS2) was immunohistochemically assessed in 35 mucinous breast carcinomas and 35 histological grade- and oestrogen receptor (ER) status-matched IDC-NSTs, and in a series of 245 invasive breast cancers...........
Subsets of colorectal , gastric , pancreatic , ovarian  and endometrial tumours [22,31,33], and particularly those occurring in the hereditary nonpolyposis colorectal cancer (HNPCC) or Lynch syndrome , are characterised by microsatellite instability. Interestingly, however, MSI-H appears to be vanishingly rare in breast cancer [21,34]. Likewise, breast cancers displaying an MSI-L status are remarkably rare, whereas in tumours from other anatomical sites, such as colorectal, endometrial or ovarian cancers , this phenomenon is not as uncommon. Of note, in some anatomical sites (e.g. colorectal and ovarian), tumours displaying microsatellite instability often display a mucinous histology [32,35,36]. However, the prevalence of MSI in mucinous carcinomas of the breast has not yet been systematically addressed........
...........All 35 pure mucinous carcinomas of the breast analysed were positive for MLH1 and MSH6 as determined by IHC, and 33 out of 35 (94.2%) and 32 out of 34 cases (94.1%) showed expression of MSH2 and PMS2, respectively (Table 2 and Figure 1)............cont'd

"The synthetic lethal targeting of DNA repair pathways, as exemplified by PARP inhibitors, in cancers bearing HR DNA repair defects is showing considerable potential for delivering selective tumor cell kill while sparing normal cells, and offers a scientifically rational and potentially broad clinical application in oncology.64 Several challenges related to the development of these inhibitors remain, including the identification of robust predictive biomarkers of HR deficiency in cancers. The dissection of the underlying mechanisms of PARP inhibitor resistance and establishment of optimal drug combinations and strategies for chemoprophylaxis with these therapies remain high priorities. It is important to be aware that different PARP inhibitors may have varying potencies on individual members of the PARP superfamily and also affect other targets, resulting in distinct toxicity and efficacy profiles. In the future, it is envisioned that this tumor-specific synthetic lethal strategy with PARP inhibitors may potentially be utilized against cancers with similar molecular defects but diverse anatomical origins.118 Such a paradigm shift in drug discovery may crucially bring us closer to our ultimate goal of personalized medicine."

Targeted Epigenetic Therapies: The Next Frontier?
1. Rabiya S. Tuma
When researchers look for mutations associated with cancer, they often expect to come up with alterations in signaling molecules or transcription factors. But an increasing number of the mutations found are in genes that regulate the epigenome—a system that alters DNA structure and regulates gene activity without changing the nucleotide sequence itself.
On Sept. 8, investigators published two independent reports online—one in Science and one in the New England Journal of Medicine—showing that mutations in an epigenetic regulatory gene, ARID1a, were associated with approximately half of the ovarian clear-cell cancers tested.

High-grade, chemotherapy-resistant ovarian carcinomas overexpress epithelial cell adhesion molecule (EpCAM) and are highly sensitive to immunotherapy (RNA/IL-2/Adecatumumab)
AbstractOBJECTIVE: We evaluated the expression of epithelial cell adhesion molecule (EpCAM) and the potential of MT201 (adecatumumab), a human-monoclonal-antibody that targets EpCAM against chemotherapy-resistant ovarian disease.
STUDY DESIGN: EpCAM expression was evaluated by real-time polymerase chain reaction and flow cytometry. Sensitivity to MT201 antibody-dependent cell-mediated cytotoxicity (ADCC) and complement-dependent cytotoxicity was tested in 4-hour chromium-release assays. The effect of interleukin-2 on MT201 ADCC was also studied.
RESULTS: High messenger RNA expression by real-time polymerase chain reaction and high EpCAM surface expression by flow cytometry was detected in 71% of ovarian cancers (5 of 7 cell lines). Although these cell lines were highly resistant to complement-dependent cytotoxicity and natural killer-dependent cytotoxicity in vitro (range of killing, 0-7%), EpCAM-positive cell lines showed high sensitivity to MT201 ADCC (range of killing, 27-66%). Incubation with interleukin-2 further increased the cytotoxic activity against EpCAM-positive ovarian cancer cell lines.
CONCLUSION: MT201 may represent a novel, potentially highly effective treatment option for patients with ovarian carcinoma whose body is harboring disease refractory to chemotherapy.

Editorial :: The role of Cochrane Review authors in exposing research and publication misconduct - The Cochrane Library
Note: while important the real question is the root of the problem - cause
"At the Joint Colloquium of the Cochrane & Campbell Collaborations in Keystone in October 2010, we ran a workshop about the problems of detecting research misconduct, and had a wonderful discussion with participants. The US Office of Research Integrity defines research misconduct as: "fabrication, falsification, or plagiarism in proposing, performing, or reviewing research, or in reporting research results; fabrication is making up data or results and recording or reporting them; falsification is manipulating research materials, equipment, or processes, or changing or omitting data or results such that the research is not accurately represented in the research record; plagiarism is the appropriation of another person's ideas, processes, results, or words without giving appropriate credit; research misconduct does not include honest error or differences of opinion". The Committee on Publication Ethics (COPE) also outlines publication and research misconduct in its flowcharts for editors, and highlights redundant (duplicate) publication, changes in authorship, undisclosed conflicts of interest, and ethical problems as additional types of misconduct.

5. Finally, ovarian cancer patients swear by cancer support groups because they provide forums for comparing and contrasting side effects, the practical aspects of everyday life with the disease, and also the reality check when a patient needs to alert their physician of odd or serious side effects and when they are normal manifestations of treatment.
