WHI Study Data Confirm Short-Term Heart Disease Risks of Combination Hormone Therapy for Postmenopausal Women, February 15, 2010 News Release - National Institutes of Health (NIH)
Note: This is a re-analysis of the original study, however, between the time of the original publication and now, sub-analyses have been conducted. There continues to be wide debates on these issues.
"The NHLBI collaborates on the WHI with the National Cancer Institute, the National Institute of Arthritis and Musculoskeletal and Skin Diseases, the National Institute on Aging, and the Office of Research on Women’s Health, all parts of the NIH. Wyeth-Ayerst Research provided the medication and placebo for the hormone study."
"However, the majority of the most common gynaecological malignancies like squamous cell carcinomas of the cervix, serous papillary epithelial ovarian carcinomas and squamous cell carcinomas of the vulva are not oestrogen dependent."

The impact of outcome reporting bias in randomised controlled trials on a cohort of systematic reviews -- Kirkham et al. 340: c365 -- BMJ
"Of the 42 meta-analyses with a statistically significant result only, eight (19%) became non-significant after adjustment for outcome reporting bias and 11 (26%) would have overestimated the treatment effect by 20% or more."
Outcome reporting bias is an under-recognised problem that affects the conclusions in a substantial proportion of Cochrane reviews. Individuals conducting systematic reviews need to address explicitly the issue of missing outcome data for their review to be considered a reliable source of evidence...."

"Now, she knows that “unless you’ve truly been there and done that, you cannot truly understand what it is like,” she said. “I’m looking at this as a different phase in my life. If I turn that next corner, I will try to accept the things I cannot change and deal with it the best I know how. It will make me a stronger person.”
Confusing association with causation - common journalistic pitfall - Gary Schwitzer's HealthNewsReview Blog
"We've just posted a new guide on the importance of the language used to describe the results of observational studies. Day after day we see stories that use active powerful verbs like "prevent...boost...lower your risk...may cut death rate" to describe the results of these studies. That's misleading and inaccurate because such studies can't prove cause-and-effect. Read more about why in this detailed, thoughtful piece by Mark Zweig, MD, and Emily DeVoto, PhD. (It's actually a revision of a piece these two wrote for us two years ago. The new one fits nicely in our "Tips for Understanding Studies" section.)"

MRI of Endometriotic Cysts in Association With Ovarian Carcinoma -- Tanaka et al. 194 (2): 355 -- American Journal of Roentgenology
CONCLUSION. Endometriotic cysts with enhanced mural nodules are not always complicated with malignancy. In elderly patients, the presence of large enhanced nodules on large endometriotic cysts is more likely to indicate malignancy.
Serum CA19.9 levels are commonly elevated in primary ovarian mucinous tumours but cannot be used to predict the histological subtype -- Journal of Clinical Pathology
Conclusion: Preoperative CA19.9 levels cannot be used to predict whether a suspected ovarian mucinous tumour is benign, borderline or malignant. Markedly elevated serum levels (>1000 U/ml) may be found in benign mucinous neoplasms as well as in borderline and malignant tumours.

"Results: Overall, 36 OCR patients were enrolled. The majority of the patients (>80%) were classified as platinum resistant.....
Prospective phase III trials are warranted to evaluate the benefit and efficacy in heavily pre-treated patients with OCR."
CONCLUSION: A standardized definition of adverse events in the homecare setting is needed. Prospective cohort studies are needed to improve estimates and intervention studies should be undertaken to reduce the risk that homecare patients will experience adverse events.
PharmaLive press release: Clinical Science to publish manuscript on HTX005 ovarian cancer biomarker 'OvPlex' (plus HTX005/AGR2)
Note: the abstract included here did not indicate the number of patients involved in the studies (see prior research articles) but according to the press release showed results in stages 11/111.
"10 February 2010, Melbourne: HealthLinx Limited (ASX:HTX) has been notified by the journal Clinical Science that a manuscript submitted for review by HealthLinx scientists and collaborators at the University of Liverpool has been accepted for publication. The manuscript describes the identification of HTX005 (AGR2) as a novel biomarker released into the bloodstream of ovarian cancer patients.
The performance of the novel biomarker AGR2 will be further tested in an up-coming multi-centre, multi-national biomarker study planned by HealthLinx. Based on preliminary data it is expected that this biomarker will increase the performance of OvPlex™ to greater than 97 per cent."

"The University of Kansas Cancer Center began running a Phase I clinical trial of the anti-ovarian cancer drug Nanotax. Nanotax is a breakthrough drug because, unlike other anti-cancer drugs, it is water-soluble....The clinical trial at the University comes nearly 15 year after Nanotax was first conceived. It is one of three active clinical trials for ovarian cancer treatment in Kansas, and it’s the only one still recruiting patients. The trial is classified as Phase I because it tests the drug in a small group.

"Although limited by small case numbers, our results suggest that tubal ligation may be more strongly associated with tumors of ovarian origin, while family history of ovarian cancer primarily increases risk of tumors of tubal origin. Characterizing risk factor relationships by tumor dominance may elucidate how these exposures alter risk and help to improve prevention efforts."

Abstract/full access: What physicians want to learn about sickness certification: analyses of questionnaire data from 4019 physicians
"A majority of physicians in most types of clinics/practices, not only primary care, indicated the need for more knowledge and skills in handling sickness certification cases. Increased knowledge and skills are needed in order to protect both the health and equity of patients. However, few physicians stated that they needed more skills in filling out sickness certificates, which contradicts previous findings about such documents being of poor quality and suggests that factors other than mere knowledge and skills are involved."
Selective serotonin reuptake inhibitors and breast cancer mortality in women receiving tamoxifen: a population based cohort study (Paroxetine/Paxil/Seroxat)
CONCLUSION: Paroxetine use during tamoxifen treatment is associated with an increased risk of death from breast cancer, supporting the hypothesis that paroxetine can reduce or abolish the benefit of tamoxifen in women with breast cancer. (trade names Seroxat, Paxil)

Survival in women with MMR mutations and ovarian cancer: a multicentre study in Lynch syndrome kindreds -- Grindedal et al. 47 (2): 99 -- Journal of Medical Genetics
Conclusions: In the series examined, infiltrating ovarian cancer in Lynch syndrome had a better prognosis than infiltrating ovarian cancer in BRCA1/2 mutation carriers or in the general population. Lifetime risk of ovarian cancer of about 10% and a risk of dying of ovarian cancer of 20% gave a lifetime risk of dying of ovarian cancer of about 2% in female MMR mutation carriers.

Note: refers to time spent by genetic counselors in advising patients
CONCLUSIONS: Severe ovarian damage, occurring in gonads operated on for ovarian endometriomas, is not a rare event.
"Patients taking Paxil and tamoxifen should talk with their doctors about changing their antidepressant, Juurlink said. But he advised against abruptly discontinuing Paxil.
"There is a very real danger to stopping Paxil suddenly. There is a well-described withdrawal syndrome and the risk of depression becoming more severe," he said.
In addition, any transition to another antidepressant should be done gradually over several weeks, he said."

"Trust in a “person like yourself” has decreased from 2008 to 2009 (as have most information sources listed in the report), and dropped again in 2010. From the global 2010 Edelman report, 44% of respondents aged between 25-64 years said they would find the information from a person like them to be either ‘very credible’ or ‘extremely credible’ (down from 47% in 2009, and 58% in 2008). That’s a huge drop over the past 3 years!......Another point to keep in mind is that a “person like yourself” is not the same as a “patient like yourself”. "

Conclusion. Preoperative serum TN is a useful prognostic indicator of advanced stage for patients with OvCa.
Conclusion:"Australian gynaecologic oncologists experience considerable occupational distress while possessing high levels of personal accomplishment and job satisfaction. To maintain a healthy workforce, it is important to build on existing supports while conducting further research to identify suitable evidence-based strategies for improving the mental health of these surgeons."
Conclusions:"Although during the introductory period nerve-sparing technique brings about an improvement in voiding function, it prolongs the total operative time in comparison to traditional radical hysterectomy."
"In our study population, introduction of the RMI would improve the management of adnexal masses, with a higher percentage of ovarian cancer patients that are operated by a gynecologic oncologist. At the same time, referral of patients with non-invasive (benign and borderline) lesions would be reduced."
When ‘never-events’ occur despite adherence to clinical guidelines: The case of venous thromboembolism in clear cell cancer of the ovary compared with other epithelial histologic subtypes
Note: 'never-events' is a term used in patient safety (eg. language - near misses, etc)
"Women with CCC-O have a 2.5-times greater risk of disease related VTE than women with other histologies of epithelial ovarian cancer despite adherence to prophylactic guidelines. Given the high rate of VTE postoperatively as well as with disease recurrence, one should consider indefinite therapeutic anticoagulation in women with CCC-O. The case of CCC-O is one example of the impracticality of payment denial for ‘never-events,’ as VTE arises despite best efforts at prevention."
Conclusion: Intraperitoneal chemotherapy regimens using carboplatin or cisplatin and dropping day 8 IP paclitaxel have less toxicity and less discontinuation of therapy
Single agent carboplatin versus carboplatin plus pegylated liposomal doxorubicin in recurrent ovarian cancer: Final survival results of a SWOG (S0200) phase 3 randomized trial
Conclusion: "Despite a favorable impact of carboplatin and PLD on progression-free survival in this trial, the effect on overall survival is not statistically significant. For currently unknown reasons, administering PLD with carboplatin appears to substantially reduce the incidence of platinum-associated hypersensitivity reactions."
BACKGROUND: One of the cornerstones of ovarian cancer therapy is cytoreductive surgery, which can be performed by surgeons with different specialty training. We examined whether surgeon specialty impacts quality of life (as proxied by presence of ostomy) and overall survival for women with advanced ovarian cancer.

abstract: From randomized trial to practice: single institution experience using the GOG 172 i.p. chemotherapy regimen for ovarian cancer
Note: patients enrolled between January 2006 to December 2007 "Background: The objective of the study was to evaluate completion rates and toxic effects of an i.p. chemotherapy regimen in a cross-section of nonselected patients with ovarian cancer (OC). Conclusions: The i.p. chemotherapy regimen used in a consecutive cohort of patients carries could be completed in only a small percentage of patients. Less toxic regimens with higher acceptability should be considered."
Chemotherapy Resistance as a Predictor of Progression-Free Survival in Ovarian Cancer Patients Treated with Neoadjuvant Chemotherapy and Surgical Cytoreduction Followed by Intraperitoneal Chemotherapy: A Southwest Oncology Group Study
re: tumour assay testing
"Conclusions: While the small patient numbers in this trial do not permit definitive conclusions, these data fail to provide support for the argument that prospectively obtained in vitro data regarding platinum or paclitaxel resistance will be highly predictive of clinical outcome in advanced ovarian cancer."
Oncogene - Abstract (technical): Cadherin switching and activation of p120 catenin signaling are mediators of gonadotropin-releasing hormone to promote tumor cell migration and invasion in ovarian cancer
Definition: Cadherins - (Calcium dependant adhesion molecules) are a class of type-1 transmembrane proteins. They play important roles in cell adhesion.
Definition: Gonadotropin - hormone secreted by the anterior pituitary gland and placenta; stimulates the gonads and controls reproductive activity. A hormone that stimulates the ovaries (such as to produce estrogen).
"These results identify for the first time cadherin switching and p120ctn signaling as important targets of GnRH function and as novel mediators of invasiveness and tumor progression in ovarian cancer."

Cochrane Collaboration Review: Retroperitoneal drainage versus no drainage after pelvic lymphadenectomy for the prevention of lymphocyst formation in patients with gynaecological malignancies
Placement of retroperitoneal tube drains has no benefit in prevention of lymphocyst formation after pelvic lymphadenectomy in patients with gynaecological malignancies. When the pelvic peritoneum is left open, the tube drain placement is associated with a higher risk of short and long-term symptomatic lymphocyst formation.

Antibodies Against Abnormal Glycoproteins Identified as Possible Biomarkers for Cancer Detection press release - National Institutes of Health (NIH)
"The team used this approach to screen blood specimens from breast, ovarian and prostate cancer patients....They found distinct abnormal mucin-type O-glycopeptide epitopes (parts of molecules that antibodies will recognize and bind to) that were targeted by autoantibodies in cancer patients — but such antibodies were absent in healthy controls.....Although larger sets of specimens will have to be analyzed to fully appreciate the clinical value of this technology, the preliminary results are very promising.The study was an international collaboration that was funded in part by NCI through the trans-NIH Alliance of Glycobiologists for Detection of Cancer and Cancer Risk."

"It's very frustrating for patients and for researchers that there hasn't been significant advances in ovarian cancer," says Dr. Tanja Pejovic, a gynecologic oncologist and associate professor at Oregon Health & Science University......Pejovic's group at OHSU is among those seeking to understand the basic biology as a means to zero in on likely markers of early disease. In a study reported in December, the group monitored the action of 69 genes in cells that make up the ovarian surface epithelium. They identified a set of genes that appear to become more active as cell
