Clinicopathologic characteristics with different BRCA1/2 status.

For categorical data (Tumor stage and grade, residual tumor size, response to chemotherapy therapy and platinum status), the Fisher exact test was used to calculate P value in R; for continuous variable such as age, the Wilcoxon rank sum test was used in R. Patients with debulking status “no macroscopic disease” are labeled as 0 cm in residual tumor size. Number (NO.) depicts the corresponding number of patients in each category. Missing values are excluded from the test analyses. BRCA wild-type cases do not include the BRCA1 methylation cases.Clinicopathologic characteristics with different BRCA1/2 status.
