The aim of this study is to determine a national consensus on the role of an objective assessment of technical surgical skills in gynecological oncology (GO).After approval was obtained from Society of Gynecologic Oncology of Canada, A panel of 20 GO leaders was assembled, representing all GO fellowship programs, and was asked to participate in an anonymous group and respond to an online 49-item questionnaire using a modified Delphi methodology.Ninety-five percent (n = 19) of those invited to participate did so. Seventeen of the panelists (89.5%) believed there was no sufficiently standardized technical skills assessment for GO fellows, whereas 18 responders (95%) believed that fellows should be objectively assessed on more than 1 occasion during their training. Consensus was predefined as Cronbach α greater than 0.8. The panel agreed on what procedures should be objectively assessed with a Cronbach α of 0.967. An overall Cronbach α of 0.993 was achieved after a single Delphi round.We achieved consensus on the possible components and logistics of a skills assessment process among a group of highly experienced GO trainers in Canada. This study provides the basis for further investigation and debate on the potential value, necessity, and feasibility of an assessment of advanced surgical and nonsurgical skills of GO trainees.

In a population-based sample of epithelial ovarian cancers, the objective of this study was to evaluate the association between microsatellite instability (MSI) status and the following factors: (1) ovarian cancer risk factors and (2) the distribution of the specific histologic subtypes.Participants were drawn from 3 population-based studies of primary epithelial ovarian cancer; tumor DNA was analyzed using 5 standardized microsatellite markers to assess the MSI status. Patients were divided into 3 groups (MSI-high, MSI-low, and MSI-stable) according to the National Cancer Institute criteria. We compared the prevalence of specific known risk and protective factors among the 3 subgroups, including body mass index, smoking history, parity, BRCA1 and BRCA2 mutation status, past oral contraceptive use, and tubal ligation. Similarly, we compared the distribution of the histologic subtypes among the 3 subgroups.A total of 917 ovarian cancer patients were included. One hundred twenty-seven cases of cancer (13.8%) were MSI-high. Subgroup analyses according to smoking, body mass index, parity, past oral contraceptive use, and past tubal ligation did not reveal any statistically significant differences among the groups. Among the 29 patients with BRCA1 mutations, 20.7% had MSI-high cancers compared with 5.9% among 17 patients with BRCA2 mutations. The proportions of different ovarian cancer histologies among the various MSI subgroups were similar.The prevalence of risk and protective factors among ovarian cancer patients is similar for cancers with and without MSI. The distributions of MSI do not differ significantly among ovarian cancers with different histologies. Ovarian cancer patients with BRCA1 mutations had a 21% rate of MSI-high tumors compared with 6% among patients with BRCA2 mutations, but this difference was not statistically significant.

To determine the incidence of BRCA1 and BRCA2 mutations in an enlarged series of uterine serous carcinoma (USC) patients and to determine whether patients with USC are associated with a personal or familial history of breast or ovarian carcinoma.A cohort of all consecutive patients with diagnosed USC was identified for 9 years. Family pedigrees were drawn as far back and laterally as possible. In all patients, genomic DNA was extracted from peripheral blood samples and analyzed for the 3 mutations common in Ashkenazi Jewish patients. All patients went through total abdominal hysterectomy, bilateral salpingo-oophorectomy, and omentectomy. Tubal, ovarian, and peritoneal carcinoma were ruled out clinically and pathologically in all patients.Of 51 consecutive patients with USC in Ashkenazi Jews studied, we identified 13 patients (25.5%) who were previously found to have breast carcinoma, 17 patients (33.3%) who had a first-degree relative with breast or ovarian carcinoma, and 8 patients (15.7%) who were found to be carriers of 1 of the 3 BRCA germline mutations.This series of USC patients, the largest consecutive series to date, suggests a higher incidence of BRCA carriers among Ashkenazi Jews as compared with the general population. This high rate of BRCA germline mutations in USC patients coupled with a high rate of personal and familial cancer histories may suggest that USC is associated with the hereditary breast-ovarian syndrome. This potential association of USC to the BRCA-associated cancer spectrum may have implications for the clinical management and intervention of unaffected BRCA1-2 germline mutation carriers. However, at the current time, there are insufficient data to provide evidence-based guidelines regarding the optimal timing or specific intervention to prevent cancers in these high-risk women.

Recent studies have indicated that the risk associated with tamoxifen may be substantially higher for uterine malignant mixed müllerian tumors and uterine sarcomas.We present 2 cases of ovarian carcinosarcomas in patients with a personal history of breast carcinoma who were treated for a prolonged period with tamoxifen.To our knowledge, these 2 cases are the first to describe the possible association between ovarian carcinosarcomas and previous personal and familial history of breast carcinoma and\or prolonged use of tamoxifen. These cases may suggest that like in the uterus, tamoxifen has a possible delayed effect, which might be responsible for the formation of aggressive tumors of unclear pathogenesis in the ovaries.
