- PURPOSE: One attempt to improve long-term survival in patients with advanced ovarian cancer was thought to be the addition of more non-cross-resistant drugs to platinum-paclitaxel combination regimens. Gemcitabine was among the candidates for a third drug.PATIENTS AND METHODS: We performed a prospective, randomized, phase III, intergroup trial to compare carboplatin plus paclitaxel (TC; area under the curve [AUC] 5 and 175 mg/m(2), respectively) with the same combination and additional gemcitabine 800 mg/m(2) on days 1 and 8 (TCG) in previously untreated patients with advanced epithelial ovarian cancer. TC was administered intravenously (IV) on day 1 every 21 days for a planned minimum of six courses. Gemcitabine was administered by IV on days 1 and 8 of each cycle in the TCG arm.RESULTS: Between 2002 and 2004, 1,742 patients were randomly assigned; 882 and 860 patients received TC and TCG, respectively. Grades 3 to 4 hematologic toxicity and fatigue occurred more frequently in the TCG arm. Accordingly, quality-of-life analysis during chemotherapy showed a disadvantage in the TCG arm. Although objective response was slightly higher in the TCG arm, this did not translate into improved progression-free survival (PFS) or overall survival (OS). Median PFS was 17.8 months for the TCG arm and 19.3 months for the TC arm (hazard ratio [HR], 1.18; 95% CI, 1.06 to 1.32; P = .0044). Median OS was 49.5 for the TCG arm and 51.5 months for the TC arm (HR, 1.05; 95% CI, 0.91 to 1.20; P = .5106).CONCLUSION: The addition of gemcitabine to carboplatin plus paclitaxel increased treatment burden, reduced PFS time, and did not improve OS in patients with advanced epithelial ovarian cancer. Therefore, we recommend no additional clinical use of TCG in this population.

- The 4th Ovarian Cancer Consensus Conference of the Gynecologic Cancer InterGroup was held in Vancouver, Canada, in June 2010. Representatives of 23 cooperative research groups studying gynecologic cancers gathered to establish international consensus on issues critical to the conduct of large randomized trials. Group C, 1 of the 3 discussion groups, examined recurrent ovarian cancer, and we report the consensus reached regarding 4 questions. These included the following: (1) What is the role of cytoreductive surgery for recurrent ovarian cancer? (2) How do we define distinct patient populations in need of specific therapeutic approaches? (3) Should end points for trials with recurrent disease vary from those of first-line trials? (4) Is CA-125 progression alone sufficient for entry/eligibility into clinical trials?

- ARID1A (BAF250a) is a component of the SWI/SNF chromatin modifying complex, plays an important tumour suppressor role, and is considered prognostic in several malignancies. However, in ovarian carcinomas there are contradictory reports on its relationship to outcome, immune response, and correlation with clinicopathological features. We assembled a series of 1,623 endometriosis-associated ovarian carcinomas, including 1,078 endometrioid (ENOC) and 545 clear cell (CCOC) ovarian carcinomas through combining resources of the Ovarian Tumor Tissue Analysis (OTTA) Consortium, the Canadian Ovarian Unified Experimental Resource (COEUR), local, and collaborative networks. Validated immunohistochemical surrogate assays for ARID1A mutations were applied to all samples. We investigated associations between ARID1A loss/mutation, clinical features, outcome, CD8+ tumour-infiltrating lymphocytes (CD8+ TIL), and DNA mismatch repair deficiency (MMRd). ARID1A loss was observed in 42% of CCOC and 25% of ENOC. We found no associations between ARID1A loss and outcomes, stage, age, or CD8+ TIL status in CCOC. Similarly, we found no association with outcome or stage in endometrioid cases. In ENOC, ARID1A loss was more prevalent in younger patients (p=0.012), and associated with MMRd (p<0.001), and presence of CD8+ TIL (p=0.008). Consistent with MMRd being causative of ARID1A mutations, in a subset of ENOC we also observed an association between ARID1A loss-of-function mutation as a result of small indels (p=0.035, versus single nucleotide variants). In ENOC, the association between ARID1A loss, CD8+ TIL, and age, appears confounded by MMRd status. Although this observation does not explicitly rule out a role for ARID1A influence on CD8+ TIL infiltration in ENOC, given current knowledge regarding MMRd, it seems more likely that effects are dominated by the hypermutation phenotype. This large dataset with consistently applied biomarker assessment now provides a benchmark for the prevalence of ARID1A loss-of-function mutations in endometriosis-associated ovarian cancers and brings clarity to the prognostic significance.

- Objective Clinical genetic testing is commercially available for rs61764370, an inherited variant residing in a KRAS 3′ UTR microRNA binding site, based on suggested associations with increased ovarian and breast cancer risk as well as with survival time. However, prior studies, emphasizing particular subgroups, were relatively small. Therefore, we comprehensively evaluated ovarian and breast cancer risks as well as clinical outcome associated with rs61764370. Methods Centralized genotyping and analysis were performed for 140,012 women enrolled in the Ovarian Cancer Association Consortium (15,357 ovarian cancer patients; 30,816 controls), the Breast Cancer Association Consortium (33,530 breast cancer patients; 37,640 controls), and the Consortium of Modifiers of BRCA1 and BRCA2 (14,765 BRCA1 and 7904 BRCA2 mutation carriers). Results We found no association with risk of ovarian cancer (OR = 0.99, 95% CI 0.94-1.04, p = 0.74) or breast cancer (OR = 0.98, 95% CI 0.94-1.01, p = 0.19) and results were consistent among mutation carriers (BRCA1, ovarian cancer HR = 1.09, 95% CI 0.97-1.23, p = 0.14, breast cancer HR = 1.04, 95% CI 0.97-1.12, p = 0.27; BRCA2, ovarian cancer HR = 0.89, 95% CI 0.71-1.13, p = 0.34, breast cancer HR = 1.06, 95% CI 0.94-1.19, p = 0.35). Null results were also obtained for associations with overall survival following ovarian cancer (HR = 0.94, 95% CI 0.83-1.07, p = 0.38), breast cancer (HR = 0.96, 95% CI 0.87-1.06, p = 0.38), and all other previously-reported associations. Conclusions rs61764370 is not associated with risk of ovarian or breast cancer nor with clinical outcome for patients with these cancers. Therefore, genotyping this variant has no clinical utility related to the prediction or management of these cancers.

- Purpose To present a single center outcome from an initial series of gynecological robotic cases with a special reference to obese patients. Methods A retrospective evaluation of 116 women, undergoing elective gynecologic robot-assisted surgery from February 2011 to December 2012. Procedures included hysterectomy (HE), radical HE, adnexectomy, myomectomy, pelvic lymphadenectomy and paraaortic lymphadenectomy, sentinel node extraction, and omentectomy. The feasibility and outcome were investigated in relation to normal and high body mass index (BMI < 30 and BMI ≥ 30). Results The overall complication rate was low (15/116; 12.9 %). The number of perioperative complications was not different between the patients with normal BMI compared to those with high BMI. Five operations were converted to open surgery due to vascular injury (2), intestinal injury (2) and one insufficiently exposed paraaortic field in an endometrial cancer patient. Urinary bladder was injured once. Late complications included vaginal dehisce (2), vaginal hemorrhage (1), cuff hematoma (4), lymphocyst (1) and two urinary tract injuries. The rate of the late complications was not significantly different in the two groups of patients (p = 0.139). A significant difference in patients’ positioning time was observed between normal weighted and obese patients (35 and 55 min, p < 0.001). Conclusion Robotic procedure was feasible and could be implemented for treating the first setting of mixed indications for gynecologic surgery. Robotic surgery may offer particular advantages in obese patients with no conversions and no wound complications.
