Key Points

The study aims to evaluate the effectiveness of prophylactic surgeries in reducing cancer risk for BRCA1/2 variant carriers.
Conducted a retrospective cohort study at a single German center.
Assessed outcomes of prophylactic mastectomy and salpingo-oophorectomy.
Compared ipsilateral cancer prevalence between mastectomy and breast-sparing surgery.
Prophylactic surgeries showed high oncological effectiveness in germline variant carriers.
Mastectomy provided greater protection against ipsilateral cancer compared to breast-conserving surgery.
Further studies are needed to explore cancer prevalence differences.

Abstract

Prophylactic surgeries demonstrate high oncological effectiveness in gPV BRCA1/2 carriers. In particular, mastectomy may provide greater protection against ISC compared with BCS. Further studies will have to be conducted to compare ipsilateral cancer prevalence after breast-sparing surgery and mastectomy.
