Current Situation and Future Directions of Risk-reducing Salpingo-oophorectomy

Abstract

High-grade serous carcinoma (HGSC), the most aggressive subtype of epithelial ovarian cancer, is strongly associated with hereditary breast and ovarian cancer (HBOC) syndrome and is primarily linked to germline BRCA1/2 pathogenic variants (PVs). The cumulative risks of ovarian cancer by the age of 70 years are 40% and 18% for carriers of BRCA1 and BRCA2 PVs, respectively. Risk-reducing salpingo-oophorectomy (RRSO) is a recommended preventive strategy that reduces the risk of ovarian cancer by more than 80% and may improve overall survival. However, surgical menopause after RRSO poses several challenges, including infertility and hormonal deficiency. Although the use of hormone replacement therapy may alleviate symptoms, it requires careful consideration of breast cancer risk. Emerging strategies, such as prophylactic salpingectomy with delayed oophorectomy, are being investigated to balance cancer prevention and patient quality of life. Further research is required to refine personalized prevention and management approaches for HBOC-associated ovarian cancer.
