Correspondence/Response: Patient Information and Decision Aids in Oncology: Need for Communication Between Patients and Physicians — JCO
1):
Correspondence (Vodermark):
"In their recent contribution to Journal of Clinical Oncology, Brace et al1 report on the knowledge and opinions of physicians caring for patients with cancer in the province of Ontario, Canada, about patient decision aids......Brace et al1 must be congratulated for collecting this comprehensive data set on the oncologists' perspective on this important topic. However, it is possible that the rates of decision aid use by patients may actually be higher than suggested by the percentages for physicians responding to the questionnaire. Access to disease-specific patient decision aids is provided freely on the Internet, and patients may make use of these tools without discussing them with their treating oncologists..."cont'd

Response to Vodermark (Erin D. Kennedy):
We appreciate the comments by Vordermark1 about our recent contribution to Journal of Clinical Oncology.2
"...We agree that the Internet certainly has the potential to be an excellent and accessible information resource for both patients and physicians. The results presented by Vordermark et al3 and Adler et al4 are both interesting and timely, given that these data suggest that patients seeking information on the Internet are not comfortable discussing the information with their physicians. This is similar to our own group's experience in which patients seem to be increasingly more confident in the information they find on the Internet rather than in their own physicians. This is somewhat concerning, and we must begin to question whether we as physicians are slowly losing the ability to connect with our patients.......To accomplish this, researchers need to involve (not avoid) physicians in both the development and implementation of pDAs and decision support tools.

Women's Health Matters Network: Women's College Hospital (Toronto) patient survey (n=1,000)
Some background:
The new facility will include the Women’s College Research Institute (WCRI), making women’s health research a key focus.
‘Our research institute is one of the few in the world – and the only one in Canada – devoted to women’s health and innovations in ambulatory care,’ said Dr. Lorraine Lipscombe, an endocrinologist at Women’s College Hospital and a scientist at the WCRI who spoke at the event.
‘Our scientists ask questions that are not only unique to women’s lives, but that are specific to distinct communities of women.’
Selected results:
"Some notable results:
* Only 30 per cent of respondents said they felt empowered when dealing with health-care providers. A great many women had less positive feelings: 45 per cent said they felt isolated when visiting a hospital, 57 per cent said they felt afraid, 63 per cent felt frustrated and 76 per cent felt anxious.
* Sixty-five per cent of women felt they were treated like a number rather than a person, and 70 per cent felt the focus was on rushing them through their appointments and treatments rather than discussing their needs and circumstances.
* The vast majority – 88 per cent of respondents – said it was essential to approach health care holistically, treating the whole person rather than isolated body parts. However, less than half that number (43 per cent) felt that hospitals and health-care facilities actually achieved this.
* Most women prefer to remain in the community – and in their lives – while their conditions are treated. Ambulatory care – or outpatient treatment, as opposed to being admitted to hospital – was the preference of 90 per cent of respondents.
* A health-care facility that is knowledgeable about, sensitive to, and actively addresses diverse cultures was important to 80 per cent of respondents.
* More than 85 per cent of women feel women’s health issues should be a research priority for a health-care institution. However, only 56 per cent think institutions successfully keep women’s health at the forefront of research programs."

Ovarian cancer care for the underserved: Are surgical patterns of care different in a public hospital setting? abstract
CONCLUSIONS:
Ovarian cancer patients treated in public hospitals are less likely to have gynecologic oncologists and high-volume surgeons involved in their care. This is a preliminary finding that warrants further investigation.OpenNotes Project "levels the playing field" between doctors and patients -- Canadian Medical Association Journal
"....The OpenNotes Project aims to improve communication and transparency between doctors and patients, many of whom don’t even realize notes are being taken, says Dr. Tom Delbanco, a lead investigator of the study. "We share these notes with consultants, insurers and people who evaluate quality of care, but almost never with the patient. I think providers feel these are their own records, rather than their patients’, so in quiet ways, perhaps unconsciously, they build up obstacles to patients gaining access to them." As in Canada, American patients have a legal right to review their doctors’ notes as part of their medical records. However, those who wish to gain access to the files often face prohibitive printing or copying fees, lengthy processes and delays, as well as all manner of bureaucratic red tape, says Delbanco. "At the same time, it’s been shown patients remember very little of what goes on in the examining room."...cont'd

Incidentally… avoiding the problem of incidental findings (Practical Ethics)
"A new study from the Mayo clinic
in the United States points to a frequent problem in certain types of
medical research. When healthy volunteers or patients with a given
condition take part in research studies they may have brain scans, CAT
scans, blood tests or genetic tests that they wouldn’t otherwise have
had. These tests are not done for the benefit of the individual, they
are designed to answer a research question. But sometimes, quite often
according to the authors of this new study, researchers may spot
something on the scan that shouldn’t be there, and that could indicate a
previously undiagnosed health condition. These ‘incidental findings’ generate an ethical dilemma for researchers....."cont'dIncreased risk of other cancers for relatives of women with early onset breast cancer | e! Science News
Published: Wednesday, September 29, 2010 - 18:23

"The results suggest there could possibly be undiscovered genes causing breast cancer in these young women, and perhaps other cancers in their families," Professor Hopper said.
Every year in Australia, more than 300 women are diagnosed with breast cancer before the age of 35 years. This is approximately one in 40 of all breast cancers.
In the largest population based study of its kind, scientists studied 2200 parents and siblings of 500 women diagnosed with breast cancer before the age of 35 from across three countries, Australia, Canada and the United States.
After excluding families with mutations in BRCA1 and BRCA2, the two known major breast cancer susceptibility genes, they found that close relatives were at increased risk of not only breast cancer, but also of cancers of the prostate, lung, brain and urinary tract.
The results showed:
- Fathers and brothers had a 5-fold increased risk of prostate cancer.
- Mothers and sisters had a 2-fold increased risk of ovarian cancer as well as a 4-fold increased risk of breast cancer
- Close relatives also had a 3-fold increased risk for brain cancer, an 8-fold increased risk for lung cancer, and a 4-fold increased risk for urinary tract cancers.
"The results of this study could help scientists discover new cancer susceptibility genes that explain the risk of early-onset and other cancers within some families," he said.
"Our next step is to conduct larger studies to further clarify these results."

abstract: Pancreatic Cancer Screening in a Prospective Cohort of High-Risk Patients: A Comprehensive Strategy of Imaging and Genetics — Clinical Cancer Research
Results:
Fifty-one patients in 43 families were enrolled, with mean age of 52 years, 35% of whom were male. Of these patients, 31 underwent EUS and 33 MRI. EUS revealed two patients with pancreatic cancer (one resectable, one metastatic), five with intraductal papillary mucinous neoplasms (IPMN), seven with cysts, and six with parenchymal changes. Five had pancreatic surgery (one total pancreatectomy for pancreatic cancer, three distal and one central pancreatectomy for pancreatic intraepithelial neoplasia 2 and IPMN).
A total of 24 (47%) had genetic testing (19 for BRCA1/2 mutations, 4 for CDKN2A, 1 for MLH1/MSH2) and 7 were positive for BRCA1/2 mutations. Four extrapancreatic neoplasms were found: two ovarian cancers on prophylactic total abdominal hysterectomy and bilateral salpingo-oophorectomy, one carcinoid, and one papillary thyroid carcinoma. Overall, 6 (12%) of the 51 patients had neoplastic lesions in the pancreas and 9 (18%) had neoplasms in any location. All were on the initial round of screening. All patients remain alive and without complications of screening.

abstract: Managing menopausal symptoms and depression in tamoxifen users: Implications of drug and medicinal interactions
OBJECTIVE: Tamoxifen, a medication used in the treatment of breast cancer, often induces menopausal symptoms. Certain medications and natural supplements taken or prescribed to alleviate tamoxifen-induced hot flashes and depressive states in women with breast cancer interact with tamoxifen. This paper reviews potentially problematic interactions and offers treatment recommendations.
CONCLUSIONS: Clinicians should remain cautious about using strong inhibitors and/or inducers of cytochrome 2D6 and 3A4 concomitantly with tamoxifen. Use of natural menopausal supplements and diets rich in isoflavones should not be encouraged in tamoxifen users until more data is available. There are however safe treatments for hot flashes and depression in tamoxifen users.

Some oncologists have expressed the concern that a referral to palliative care would destroy a patient's hope. It is important to recognize that patients do not need to choose between cancer treatments and supportive/palliative care. Rather, they can take advantage of the expertise of both the oncology and the palliative care teams in optimizing quantity and quality of life under a simultaneous care model......"

Mayo Collaboration Finds Source of Breast Drug Side Effect
Pharmacogenomic discovery allows for improved cancer therapy
ROCHESTER, Minn. — Mayo Clinic researchers and their international colleagues have discovered genetic variants that lead to severe arthritis for a subset of women when taking aromatase inhibitors to treat their breast cancer. This serious side effect is so painful that many women halt their lifesaving medication. The findings appear today in the online issue of Journal of Clinical Oncology.

Quality of pathology reports for advanced ovarian cancer: Are we missing essential information? An audit of 479 pathology reports from the EORTC-GCG 5
Quality of pathology reports for advanced ovarian cancer: Are we missing essential information? An audit of 479 pathology reports from the EORTC-GCG 55971/NCIC-CTG OV13 neoadjuvant trial
CONCLUSION: This audit of ovarian cancer pathology reports reveals that in a substantial number of reports basic pathologic data are missing, with possible adverse consequences for the quality of cancer care. Specialisation by pathologists and the use of standardised synoptic reports can lead to improved quality of reporting. Further research is needed to better define pre- and post-operative diagnostic criteria for ovarian cancer treated with neoadjuvant chemotherapy.

Prognostic value of microsatellite instability (MSI) and PTEN expression in women with endometrial cancer: results from studies of the NCIC Clinical Trials Group (NCIC CTG)
Abstract
AIM: The impact of PTEN status and microsatellite instability (MSI) on the prognosis of women with endometrial cancer is controversial. The aim of this study was to investigate MSI and PTEN expression in two patient populations using data from NCIC CTG studies.METHODS: Archival paraffin embedded tumour from women with endometrial cancer enrolled in NCIC CTG studies: EN5 (stage I/II) and IND 126, 148 and 160 (advanced/recurrent disease) were examined for MSI using BAT25/26 and for PTEN expression using immunohistochemistry. PTEN and MSI status were correlated with clinicopathologic variables and survival using data from NCIC CTG trial databases.
RESULTS: PTEN and MSI results were available from 128 and 163 patients, respectively. MSI+ tumours were more common in women enrolled in EN5 compared to the IND studies (p=0.01). PTEN negative tumours were associated with improved survival in both univariate (hazard ratio (HR) 0.55, 95% confidence interval (CI) 0.32-0.94; p=0.03) and multivariate (adjusted HR 0.54, 95% CI 0.30-0.96; p=0.03) analyses in women enrolled in IND studies. Microsatellite stable tumours were associated with an improved prognosis in univariate (HR 0.18, 95% CI 0.06-0.51; p<0.0001)>
CONCLUSIONS: PTEN negative tumours in women with advanced disease are associated with improved survival. MSI+ tumours are more common in early stage disease and in this group of women are associated with a worse prognosis
abstract: Will designated patient navigators fix the problem? Oncology nursing in transition
Abstract
With increasing concern for equity and access across the cancer care system, we have seen expanding enthusiasm for various forms of designated patient "navigators" to facilitate coordination. While the intention is laudable, many of the popular implementation strategies risk accentuating strain upon the system and further complicating the coordination problem. These authors claim the motivation underlying the navigator movement can be reframed as an emerging recognition of the value of nursing work when it is optimally positioned to support patients, as they experience the cancer care system. This paper calls on Canadian oncology nurses to critically challenge navigation strategies, and adopt only those consistent with the significant reforms required to ensure a cancer care system so effective that external navigators are no longer necessary.

BRCA1 mutations and colorectal cancer in Poland
Abstract
Evidence to date that germline mutations in the tumor suppressor gene BRCA1 increase the incidence of colorectal cancer is mixed, and both positive and negative results have been reported. To establish whether or not inherited variation in BRCA1 influences the risk of colorectal cancer, we genotyped 2,398 unselected patients with colorectal cancer and 4,570 controls from Poland for three BRCA1 founder mutations (C61G, 4153delA and 5382insC). A BRCA1 mutation was present in 0.42% of unselected cases of colorectal cancer and in 0.48% of controls (OR = 0.8; P = 0.8). The mutation frequency was slightly higher (0.93%) in 321 cases who reported a family history of colon cancer in a first- or second-degree relative (OR = 1.9; P = 0.5). A BRCA1 mutation was also seen in excess (0.82%) in 851 cases who were diagnosed with colorectal cancer at age 60 or earlier (OR = 1.7; P = 0.3). The mean age at onset in carriers was 7 years younger than in non-carriers (57.0 years vs. 64.0) and the difference was significant (P = 0.05). This study suggests that BRCA1 mutations may be associated with early-onset of colorectal cancer.
Mucosal carcinoma of the fallopian tube coexists with ovarian cancer of serous subtype only: a study of Japanese cases
Abstract
Previous studies in Western countries have revealed that mucosal carcinoma of the fallopian tube frequently coexists with pelvic (ovarian, tubal, and peritoneal) serous carcinomas, and early tubal carcinoma is now regarded as a possible origin of these tumors. However, the relationship between early tubal carcinoma and non-serous ovarian cancer, such as clear cell adenocarcinoma, has not been studied in detail. In this study, we sought to examine the coexistence of mucosal carcinoma of the fallopian tube in Japanese ovarian cancer cases. We submitted the fallopian tubes in toto for histological examination in 52 ovarian carcinoma cases and three peritoneal serous carcinoma cases. The ovarian tumors included 12 serous adenocarcinomas, 23 clear cell adenocarcinomas, nine endometrioid adenocarcinomas, three mucinous adenocarcinomas, and four mixed epithelial carcinomas. Mucosal carcinoma of the fallopian tube did not coexist with non-serous adenocarcinoma (n = 40). In contrast, mucosal carcinoma of the fallopian tube was observed in six cases of ovarian serous adenocarcinoma and one case of peritoneal serous adenocarcinoma. In these cases, the p53 immunophenotypes were similar in tubal lesions and invasive ovarian or peritoneal carcinomas. Tumors were negative for p53 in four of seven cases, and one of the p53-negative serous adenocarcinomas showed low-grade morphology. We believe that some ovarian and peritoneal serous adenocarcinomas develop from early tubal carcinomas. However, it should be noted that early tubal carcinomas are not always p53-positive immunohistochemically. Finally, it is unlikely that early tubal lesions are involved in the carcinogenesis of clear cell adenocarcinoma and other non-serous adenocarcinomas.

At the same time The American Recovery and Reinvestment Act of 2009 has provided USD 1.1 billion for Comparative Effectiveness Research (CER), and established the Patient-Centered Outcomes Research Institute (PCORI). PCORI will make a major annual investment in CER, through the National Institutes of Health (NIH) and the Agency for Healthcare Research and Quality (AHRQ).
The US contribution to the development of The Cochrane Collaboration has been considerable. US-based researchers represented 7/84 (8.3%) of the pioneers attending the first Cochrane Colloquium in October 1993........."cont'd

(repeat) abstract: SGO White Paper on ovarian cancer: etiology, screening and surveillance
Abstract: Ovarian cancer is a heterogeneous, rapidly progressive, highly lethal disease of low prevalence. The etiology remains poorly understood. Numerous risk factors have been identified, the most prominent involving an inherited predisposition in 10% of cases. Women with germline mutations associated with Hereditary Breast/Ovarian Cancer and Lynch syndromes have dramatically elevated risks (up to 46% and 12%, respectively). Risk-reducing salpingo-oophorectomy is the best method to prevent ovarian cancer in these high-risk women. Significant risk reduction is also seen in the general population who use oral contraceptives. Since up to 89% patients with early-stage disease have symptoms prior to diagnosis, increased awareness of the medical community may facilitate further workup in patients who otherwise would have had a delay. Despite enormous effort, there is no proof that routine screening for ovarian cancer in either the high-risk or general populations with serum markers, sonograms, or pelvic examinations decreases mortality. Further evaluation is needed to determine whether any novel biomarkers, or panels of markers, have clinical utility in early detection. Prospective clinical trials have to be designed and completed prior to offering of any of these new diagnostic tests. CA125 is currently the only biomarker recommended for monitoring of therapy as well as detection of recurrence. This commentary provides an overview on the background, screening and surveillance of ovarian cancer.

Detecting ovarian cancer in primary care
• Refer urgently if physical examination identifies a pelvic or abdominal mass and/or ascites.
• Investigate if a woman reports any of the following more than 12 times a month: abdominal distension, difficulty eating and/or feeling full, pelvic or abdominal pain or increased urinary urgency and/or frequency
• Also consider testing woman with abnormal vaginal bleeding, unexplained weight loss, abdominal distension, fatigue or changes in bowel habit.
• Send women with a serum CA125 35 IU/ml for an ultrasound scan and refer with a positive scan urgently for further investigation.
• Advise any woman who has normal serum CA125, or a normal ultrasound, to return to her GP for re-assessment if her symptoms persist or become more frequent.

U.S. - Stanford study of program for cancer survivors needs participants
Now, researchers at the Stanford University School of Medicine are looking for participants for a study on the program, which was designed to help people get the most out of life while living with cancer. This study is specifically for patients who have had cancer more than once.
Participants are needed who have had at least two bouts of cancer and have completed major treatment in the past five years. Participants can live anywhere in the United States but need access to a computer with an Internet connection and an e-mail account.
Those who are interested in participating should visit http://cancersurvivors.stanford.edu or e-mail cancersurvivors@stanford.edu.
“Cancer: Thriving and Surviving” is a six-week, Internet-based workshop intended to help people living with cancer deal with their unique problems and concerns, which can include fear of reoccurrence, depression, fatigue and a sense of isolation. Each workshop brings together online about 25 people and is facilitated by two trained moderators — at least one of whom is a cancer survivor, like Gaynor Watson.
The study will assess the workshop’s effectiveness.
The workshop is an adaptation of a chronic-disease-management program developed by Kate Lorig, DrPH, professor emeritus of immunology and rheumatology, that has been shown to be effective at improving health and well-being for participants.
To evaluate this new program, Lorig and colleagues at the University of Hawaii previously enrolled 400 first-time cancer survivors in the cancer course; now the study has been expanded to include patients with a recurring or second cancer.
Gaynor Watson said past participants have benefited from the sense of camaraderie with their online peers and from the ability to communicate with others who relate to what they’re doing. Her hope, she said, is that they also walk away with “a sense of self-empowerment and the skills to live a quality life.”
During the study, survivors will be randomly assigned to participate in a workshop, or to wait six months to take the workshop. Those enrolled in the online program will have access to a Web-based learning center and online discussion boards to address such topics as healthy eating, physical activity, stress and fatigue management, communication and emotional strategies. They’ll be asked to log on two or three times for a total of about two hours each week over the six-week period; all participants will complete two online questionnaires about their health over a six-month period.
The study, which is being conducted in the Stanford Patient Education Research Center, is funded by the Stanford Cancer Center.
Australian women's awareness of ovarian cancer symptoms, risk and protective factors and estimates of own risk - abstract

Australian women's awareness of ovarian cancer symptoms, risk and protective factors, and estimates of own risk.
Centre for Health Initiatives, University of Wollongong, Wollongong, 2522, Australia, sandraj@uow.edu.au.
Abstract
OBJECTIVE: To examine Australian women's perceived risk of ovarian cancer, reasons for perceived risk levels, and knowledge of ovarian cancer symptoms at two timepoints (2003 and 2007).METHODS: A computer-assisted telephone (CATI) survey of 2,954 Australian women with no history of ovarian cancer was conducted.
RESULTS: Approximately 60% of women perceived their risk of ovarian cancer was similar to other women of their age; 10% indicated an increased risk, and 30% indicated a lower risk. These figures were similar in 2003 and 2007. Logistic regression found that lower income, increased age, being born overseas, and being retired were significantly associated with lower perceived risk (accounted for only 7.5% of the variance). Common reasons for higher perceived risk included family history of ovarian/other cancers, increasing age, and having had other types of cancer or health problems. Reasons for lower than average risk included absence of family history, having a hysterectomy, and having regular Pap smears (indicating confusion between ovarian and cervical cancer). There appeared to be substantial confusion in women's understanding of ovarian cancer symptoms; this was similar in 2003 and 2007.
CONCLUSION: The observed misperceptions and confusion regarding ovarian cancer symptoms and risk factors suggest ongoing public education campaigns are needed to improve knowledge and awareness.

abstract: Resident Participation Does Not Affect Surgical Outcomes, Despite Introduction of New Techniques
Abstract
BACKGROUND: Surgical operations at academic medical centers typically involve a resident physician performing cases together with, and/or under the supervision of, an attending physician. Although this is a widely accepted practice, recent emphasis on patient safety has led to scrutiny about this educational model. There are few studies evaluating whether complication rates, independent of patient risk factors, are affected by resident participation in operations.STUDY DESIGN: We identified 295 patients (590 breasts) who had undergone bilateral reduction mammoplasty led by a single attending surgeon between October 1, 1997 and September 30, 2008 at the University of Michigan Health System. In all cases, the attending operated on the right breast and the resident operated on the left breast under the supervision of the attending, allowing each patient to act as their own control. Their charts were retrospectively reviewed and major complications were defined as those requiring either an operation or hospitalization to treat.
RESULTS: Twenty-three patients (7.8%) had a major complication after their breast reduction. Ten of these complications occurred in the left breast, 9 in the right breast, and 4 in both breasts. Statistical analysis revealed no differences in major complication rates between the side operated on with the primary surgeon being the resident versus the attending (4.7% versus 4.4%; p = 1.00).
CONCLUSIONS: In the context of this single surgical operation, resident participation does not substantially affect major complication rates. The common residency training paradigm provides clinical experience and supervision without necessarily impacting patient safety. Analysis of additional operations in different settings will be necessary.
ICR (UK) - Lynch Syndrome mutation MSH2 - 60-Year-Old Drug Shows New Promise for Inherited Cancer
"....Methotrexate is similar to a normal molecule called folinic acid, which is required for copying DNA. The drug prevents cells from making and repairing DNA - a process needed for cancer growth. It was one of the first chemotherapy drugs to be invented in the 1940s and is still used to treat a number of cancers today. But until now, it has not commonly been used to treat people with HNPCC.
Professor Alan Ashworth, who led this Cancer Research UK-funded study at the ICR, said: "The MSH2 gene plays a vital role in repairing DNA damage but if it is faulty, mistakes accumulate in cells and increase the risk of cancer developing.
"What's exciting about methotrexate is that it selectively destroys the cells lacking the MSH2 function. This indicates that it may make an excellent treatment for patients with the genetic alteration. With our colleagues at The Royal Marsden Hospital, we have set up clinical trials to test this."...cont'd

Microbubble-enhanced US in Body Imaging: What Role? (abstract)
Note: CE US = contrast enhanced ultrasound
Abstract
Contrast agents for ultrasonography (US) comprise microscopic bubbles of gas in an encapsulating shell. They are unique in that they interact with the imaging process, oscillating in response to a low-intensity ultrasound field and disrupting in response to a high-intensity field. New contrast-specific imaging modes allow US to show exquisite vascularity and tissue perfusion in real time and with excellent spatial resolution. In Europe, Asia, and Canada, to name only the most obvious, characterization of focal liver masses is the first and best established use of contrast-enhanced (CE) US, allowing for the noninvasive diagnosis of commonly encountered liver masses with comparable accuracy to that of computed tomography and magnetic resonance studies. CE US is a preferred modality for the difficult task of diagnosis of liver nodules detected on surveillance scans in those at risk for hepatocellular carcinoma. Newer body applications include the guidance of ablative intervention, monitoring activity of bowel inflammation in Crohn disease, characterization of kidney masses, especially cystic renal cell carcinoma, diagnosis of prostate cancer, and monitoring the response of tumors to antivascular drug therapies. Microbubble contrast agents are easy to use and robust; their use poses no risk of nephrotoxicity and requires no ionizing radiation. CE US plays a vital and expanding role that improves management and patient care.

Letter by Antonius AntoniouFergus Couch and colleagues report a genome-wide association study for modifiers of breast cancer susceptibility in BRCA1 mutation carriers with breast cancer and BRCA1 mutation carriers without breast cancer. They identify a locus at 19p13 associated with breast cancer risk in BRCA1 mutation carriers, and replication studies show that this locus associates with estrogen receptor-negative breast cancer in the general population.

They identify a locus at 19p13 associated with susceptibility to the serous subtype of epithelial ovarian cancer.
health media: BRCA1 Breast Cancer Risk Linked To Other Genes
"...People who carry certain mutations of the BRCA1 gene are known to have a higher risk of developing breast cancer.
Couch told the media that their findings should be "useful in helping determine individual risk for breast cancer in BRCA1 carriers".
"It also provides insights into hormone-receptor-negative breast cancer in the general population," he added.
For the study, Couch and colleagues conducted four phases of genome-wide association studies (GWAS) that altogether involved 20 research centers in 10 North American and European countries and Israel.
For the first phase, to identify candidate gene variants, they scanned the genomes of 1,193 carriers of BRCA1 mutations who were under 40 and had invasive breast cancer and compared them to scans of about the same number of controls: BRCA1 carriers of similar age who did not have breast cancer.
In comparing the genomes from the two populations the researchers examined over half a million genetic alterations. They found 96 pieces of DNA called SNPs, or "snips", short for single nucleotide polymorphisms, that they thought would be likely candidates because they differed between the two populations...."cont'd

Note: excerpts below, the tables included in the paper provide interesting information including patients with borderline tumours, 24% of patients in this study had a prior hysterectomy etc...
Objective:
To describe the diagnostic pathways experienced by a large,
representative group of Australian women with ovarian cancer, and to
document the time between first presentation to a medical professional
and clinical diagnosis.
Conclusions:
Despite anecdotal suggestions to the contrary, most women with ovarian
cancer in Australia are investigated and diagnosed promptly. The
diagnostic process is more protracted for a minority of women, and the
factors we found to be associated with diagnostic delay warrant further
investigation.

EvidenceUpdates- A randomized controlled trial of home-based exercise for cancer-related fatigue in women during and after chemotherapy with or without radiation therapy
CONCLUSIONS: Our home-based exercise intervention had no effect on fatigue or related symptoms associated with cancer treatment. The optimal timing of exercise remains to be determined.
IMPLICATIONS FOR PRACTICE: Clinicians need to be aware that some physical activity is better than none, and there is no harm in exercise as tolerated during cancer treatment. Further analysis is needed to examine the adherence to exercise. More frequent assessments of fatigue, sleep disturbance, depression, and pain may capture the effect of exercise.
Comments from Clinical Raters

Impact will be muted, as this is a negative trial: exercise is not harmful but doesn't seem to improve any of the outcomes measured, including fatigue.

full free access: The Role of In Vitro Directed Chemotherapy in Epithelial Ovarian Cancer
Epithelial ovarian cancer (EOC) continues to be the most lethal gynecologic malignancy. Efforts to personalize chemotherapy treatments by utilizing in vitro tumor assays to predict chemotherapeutic response have been tested in both the primary and recurrent treatment setting. To date, several retrospective studies have suggested improved response rates to predicted chemotherapeutic agents. However, a prospective, controlled trial merely found equivalence between in vitro prediction and empirical treatment selection. This review summarizes the current data regarding in vitro directed chemotherapy in EOC.
Conclusions: In vitro chemotherapy sensitivity and resistance testing may still hold promise for clinical decision-making, improved survival, and limiting unnecessary toxicity in the treatment of EOC. Given the current limitations and lack of randomized, controlled results, these assays are best used in the setting of a clinical trial.
Sorafenib in Combination With Gemcitabine in Recurrent Epithelial Ovarian Cancer: A Study of the Princess Margaret Hospital Phase II Consortium
Princess Margaret Hospital, University of Toronto, Toronto, Ontario, Canada; †Juravinski Cancer Centre, McMaster University,Hamilton, Ontario, Canada; ‡Fox Chase Cancer Center, Philadelphia, PA; and §National Cancer Institute, Bethesda, MD.
Abstract
OBJECTIVES: Antiangiogenic strategies have demonstrated efficacy in epithelial ovarian cancer (EOC). Sorafenib is a novel multitargeted kinase inhibitor with antiangiogenic activity. Gemcitabine has known activity against EOC. A phase 1 clinical trial of this combination suggested activity in ovarian cancer with no dose-limiting toxicity. This phase 2 study was designed to examine the safety and efficacy of gemcitabine and sorafenib in patients with recurrent EOC.CONCLUSION: This trial of gemcitabine and sorafenib in recurrent EOC did not meet its primary efficacy end point, but the combination was associated with encouraging rates of prolonged stable disease and CA-125 response.

Oral contraceptive use is associated with a decrease in the prevalence of TICs.A phase I trial of dose-dense (biweekly) carboplatin combined with paclitaxel and pegfilgrastim: A feasibility study in patients with untreated Stage III and IV ovarian, tubal or primary peritoneal cancer: GOG study (serious side effects)
Purpose
Dose-dense regimens have been shown to improve outcome when given as adjuvant therapy to patients with breast cancer compared with their three weekly counterparts. We investigated the feasibility of a dose-dense regimen with carboplatin/paclitaxel followed by pegfilgrastim in patients with advanced ovarian cancer. We also investigated the toxicities including the percentage of patients with grade 2 or greater peripheral neurotoxicity and the clinical response of this regimen.Conclusion
Dose-dense carboplatin/paclitaxel appears to be effective. However, based on dose limiting toxicities occurring when administering 6 cycles of treatment, it is not feasible. Given the neuropathy and thrombocytopenia, we do not recommend 6 cycles of this regimen without modification.Genetics University of Utah - Tour of the Basics - Understanding Genes, Chromsomes

Terry Fox & the Terry Fox Foundation - the Marathon of Hope
Terry Fox & the Terry Fox Foundation
Terry Fox was born in Winnipeg, Manitoba, and raised in Port Coquitlam, British Columbia, a community near Vancouver on Canada's west coast. An active teenager involved in many sports, Terry was only 18 years old when he was diagnosed with osteogenic sarcoma (bone cancer) and forced to have his right leg amputated 15 centimetres (six inches) above the knee in 1977.While in hospital, Terry was so overcome by the suffering of other cancer patients, many of them young children, that he decided to run across Canada to raise money for cancer research.
He would call his journey the Marathon of Hope.
It was a journey that Canadians never forgot.
After 18 months and running over 5,000 kilometres (3,107 miles) to prepare, Terry started his run in St. John’s, Newfoundland on April 12, 1980 with little fanfare. Although it was difficult to garner attention in the beginning, enthusiasm soon grew, and the money collected along his route began to mount. He ran 42 kilometres (26 miles) a day through Canada's Atlantic provinces, Quebec and Ontario. However, on September 1st, after 143 days and 5,373 kilometres (3,339 miles), Terry was forced to stop running outside of Thunder Bay, Ontario because cancer had appeared in his lungs. An entire nation was stunned and saddened. Terry passed away on June 28, 1981 at the age 22.The heroic Canadian was gone, but his legacy was just beginning.
To date, close to $500 million has been raised worldwide for cancer research in Terry's name through the annual Terry Fox Run, held across Canada and around the world.
