Endocrine Therapy for Surgeons: Practical Pearls for Managing Menopausal, Bone Loss and Sexual Adverse Effects.

Breast cancer patients are living longer than ever before and as such the population of breast cancer survivors continues to grow. Approximately 80% of breast cancers are hormone receptor-positive (HR+) and most patients will receive neoadjuvant or adjuvant estrogen blockade, referred to as endocrine therapy. Although endocrine therapy reduces HR+ breast cancer recurrence by 30-50%, significant adverse effects pose a threat to treatment adherence. These adverse effects include vasomotor symptoms, colloquially referred to as hot flashes, bone loss, joint arthralgias, genitourinary syndrome of menopause (GSM), previously referred to as vaginal atrophy, and low libido. This review will present the evidence-based treatments available for each of these adverse effects, including clear treatment algorithms for GSM, which is often experienced by patients but overlooked by providers. The most important takeaway is to ask open-ended questions, encourage reporting of these symptoms, and refer patients to specialty providers as needed. Surgeons may be the first to encounter these symptoms, therefore it is critical to remain informed of the treatment options.
