Abstract
The aim of this study was to identify the uptake rate of risk-reducing salpingo-oophorectomy (RRSO) and the factors affecting this rate among female BRCA1 or BRCA2 mutation carriers at the National Cancer Center of Korea. Between April 2007 and December 2014, 450 women underwent BRCA gene testing, and 97 women were found to have BRCA1/2 mutations. Through the review of medical records, 42 candidates for RRSO were identified. Of these, 22 underwent RRSO. Demographic, clinical, and consultation-related factors were compared between the RRSO and non-RRSO groups. The uptake rate of RRSO was 52.4 %. The mean time interval between genetic testing and surgery in the RRSO group was 7.3 months (range 0.6-33.9). The prevalence of amenorrhea was greater in the RRSO group than in the non-RRSO group (59.1 % vs. 20.0 %; P = 0.010). More women in the RRSO group were consulted with gynecologic oncologists (95.5 % vs. 60.0 %; P = 0.008). In multivariate analyses, amenorrhea at the time of genetic counseling (OR 16.44; 95 % CI 1.16-232.82; P = 0.038) and consultation with gynecologic oncologists (OR 30.78; 95 % CI 1.34-707.21; P = 0.032) were identified as factors affecting the carrier's decision to undergo RRSO. One patient in the non-RRSO group (5.0 %) developed primary peritoneal carcinoma, which was diagnosed 4.6 years after genetic testing. The uptake rate of RRSO among BRCA1/2 mutation carriers was affected by the presence of amenorrhea and consultation with gynecologic oncologists. Gynecologic oncologists with clinical experience with ovarian cancer should play a major role in aiding carriers' decision-making concerning RRSO.
