Patterns of use and outcomes of adjuvant bevacizumab therapy prior to regulatory approval in women with newly diagnosed ovarian cancer

PURPOSE There are deficient data on prevalence of germline mutations in breast cancer susceptibility genes 1 and 2 ( BRCA1/ BRCA2) in Indian patients with ovarian cancer who are not selected by clinical features. METHODS This prospective, cross-sectional, noninterventional study in nine Indian centers included patients with newly diagnosed or relapsed epithelial ovarian, primary peritoneal, or fallopian tube cancer. The primary objective was to assess the prevalence of BRCA1/ BRCA2 mutations, and the secondary objective was to correlate BRCA1/ BRCA2 status with clinicopathologic characteristics. Mutation testing was performed by a standard next-generation sequencing assay. RESULTS Between March 2018 and December 2018, 239 patients with a median age of 53.0 (range, 23.0-86.0 years) years were included, of whom 203 (84.9%) had newly diagnosed disease, 36 (15.1%) had family history of ovarian or breast cancer, and 159 (66.5%) had serous subtype of epithelial ovarian cancer. Germline pathogenic or likely pathogenic mutations in BRCA1 and BRCA2 were detected in 37 (15.5%; 95% CI, 11.1 to 20.7) and 14 (5.9%; 95% CI, 3.2 to 9.6) patients, respectively, whereas variants of uncertain significance in these genes were seen in four (1.7%; 95% CI, 0.5 to 4.2) and six (2.5%; 95% CI, 0.9 to 5.4) patients, respectively. The prevalence of pathogenic or likely pathogenic BRCA mutations in patients with serous versus nonserous tumors, with versus without relevant family history, and ≤ 50 years versus > 50 years, were 40 of 159 (25.2%; 95% CI, 18.6 to 32.6) versus 11 of 80 (13.8%; 95% CI, 7.1 to 23.3; P = .0636), 20 of 36 (55.6%; 95% CI, 38.1 to 72.1) versus 41 of 203 (20.2%; 95% CI, 14.9 to 26.4; P < .0001), and 20 of 90 (22.2%; 95% CI, 14.1 to 32.2) versus 31 of 149 (20.8%; 95% CI, 14.6 to 28.2; P = .7956), respectively. CONCLUSION There is a high prevalence of pathogenic or likely pathogenic germline BRCA mutations in Indian patients with ovarian cancer.

Objectives: The aim of this study was to determine the 3-year overall survival among the epithelial ovarian cancer patients based on the histology, age, and the stage of the disease in Iran during 2011-2017. Materials and Methods: This study was a cross-sectional retrospective study that was conducted on 179 newly diagnosed patients with epithelial ovarian cancer, who had referred to the gynecologic cancers clinic in a referral training hospital in Tehran during 2011-2017. The patients’ data including the demographic characteristics of the patients, the stage of the disease, and the treatment type were analyzed based on the pathologic responses. Results: Among 220 newly diagnosed patients with epithelial ovarian cancer, 179 of them were suitable for the follow-up. There were 93 death and 85 living cases among these patients and the mean age of the patients was 50.5 ± 11.3. In addition, most of the patients were in stage 3 (60.9%) and 6.7% of them were in stage 4. The most common pathology was serous adenocarcinoma (70.9%). In this study, the overall survival rate had no connection with the type of tumor histology but it was related to the stage of the disease (P=0.05). Finally, there was no mortality in stage one and among the mucinous adenocarcinoma cases. Conclusions: The survival in the epithelial ovarian cancer was related to the stage of the disease and among all the pathologies, mucinous adenocarcinoma and clear cell carcinoma had the best survival rate.
