Simultaneous Risk-Reducing Mastectomy and Salpingo-Oophorectomy in Patients with BRCA1 and BRCA2 Pathogenic Variants: A Single-Center Retrospective Cohort Study

Background: Women carrying BRCA1 and BRCA2 pathogenic variants face a substantially increased lifetime risk of breast and ovarian cancer. Risk-reducing bilateral mastectomy and salpingo-oophorectomy are well-established strategies to lower this risk. Traditionally, these procedures are performed in separate surgical sessions; however, a simultaneous approach may reduce the overall treatment burden. Evidence regarding the safety and feasibility of combined procedures remains limited. Methods: We conducted a retrospective observational study of BRCA1 and BRCA2 pathogenic variant carriers who underwent risk-reducing or therapeutic breast surgery at the Breast Unit of Policlinico San Martino Hospital (Genova, Italy) between January 2013 and March 2025. Patients were divided into two groups according to surgical strategy: a simultaneous procedure group undergoing risk-reducing mastectomy with immediate breast reconstruction and concurrent salpingo-oophorectomy in a single operative session, and a staged procedure group undergoing the same interventions in separate surgeries. Demographic, surgical, and postoperative variables were collected and analyzed descriptively. Results: A total of 124 BRCA1 and BRCA2 pathogenic variant carriers were included, with 73 patients undergoing the simultaneous approach and 51 undergoing staged procedures. The mean age was similar between the Simultaneous and Staged Procedure Groups Descriptively, similar patterns were observed across the two groups in terms of age distribution, postoperative outcomes, and length of hospital stay (mean 4.56 days). Minor complications such as seroma or delayed wound healing showed similar patterns across both groups, with no apparent increase in major complications in the simultaneous surgery group. Patients undergoing the simultaneous approach required fewer surgical sessions and were exposed to general anesthesia only once. Conclusions: Simultaneous risk-reducing mastectomy with immediate reconstruction and salpingo-oophorectomy appears to be a safe and feasible strategy for selected BRCA1 and BRCA2 pathogenic variant carriers. This integrated surgical approach may reduce the overall surgical burden, with descriptively similar perioperative outcome patterns.
