Abstract
The optimal management of breast cancer susceptibility gene (BRCA)1/2 carriers with isolated serous tubal intraepithelial carcinoma (STIC) found at risk-reducing salpingo-oophorectomy (RRSO) is unclear. The prevalence of occult carcinoma and STIC in a consecutive series of BRCA1/2 carriers undergoing RRSO is reported. The outcome of staging procedures in BRCA1/2 carriers with isolated STIC at RRSO as well as the relationship between staging, chemotherapy treatment and risk of recurrence was assessed via a systematic review of the literature. Our series included 235 BRCA1/2 carriers who underwent RRSO. Federation of Gynaecology and Obstetrics stage IA carcinoma or STIC was found at RRSO in three (1.3%) and two (0.9%) patients, respectively. A systematic review of the literature included 82 BRCA1/2 carriers with isolated STIC found at RRSO. In 13/82 (16%) cases with STIC, staging was reported. In none of these cases staging revealed more advanced disease. Recurrent disease was found in four of 36 patients with reported follow-up. The estimated risk of recurrence in patients with isolated STIC at RRSO was about 11% (95% confidence interval 3-26%) after a median follow-up of 42 months (range 7-138). No recurrences were reported in those patients with STIC at RRSO who underwent staging or received chemotherapy. We found 1.3% occult carcinoma and 0.9% STIC at RRSO in our cohort of BRCA1/2 carriers. A systematic review of the literature suggests that additional treatment after RRSO, i.e. staging and/or chemotherapy, is associated with a lower risk of recurrence. However, data on staging and follow-up are limited.
