Surgical Ovarian Suppression and Breast Cancer—What Do We Know About It?

Abstract

Breast cancer (BC) is the most common malignancy in women worldwide, with incidence projected to rise, particularly among younger patients. In premenopausal women with hormone receptor-positive disease, ovarian suppression is an established component of systemic therapy, most often achieved pharmacologically with gonadotropin-releasing hormone agonists (GnRHas). Bilateral salpingo-oophorectomy (BSO) represents a surgical alternative that ensures definitive suppression, eliminates compliance issues, and is more cost-effective in the long term. Despite these advantages, BSO induces irreversible menopause, associated with vasomotor symptoms, cardiovascular morbidity, bone loss, cognitive decline, and reduced quality of life. Evidence suggests that BSO is most appropriate in selected cases, including women unable to tolerate or adhere to medical suppression, those with inadequate estradiol suppression, patients approaching natural menopause, individuals with metastatic hormone receptor-positive disease, and carriers of BRCA1 mutations, especially with triple-negative tumors. Conversely, data on its benefit in BRCA2 carriers remain limited. Overall, BSO provides oncologic outcomes comparable to medical suppression but at the cost of permanent systemic effects. The decision between surgical and medical ovarian suppression should be individualized, balancing oncologic efficacy, comorbidities, genetic background, and patient preference. Further studies are needed to define the optimal duration of medical suppression and clarify the role of BSO in hereditary breast cancer.
