S13 Ep2: Tailored Treatment Approaches for Older Patients With Advanced HR+/HER2– Breast Cancer

This featured podcast includes a discussion with 3 experts on managing patients with hormone receptor–positive/HER2-negative (HR+/HER2–) metastatic breast cancer (mBC) from a satellite symposium held in conjunction with the 42nd Annual Miami Breast Cancer Conference® in March 2025. In observational studies of treatment patterns in older women with mBC, approximately half of the patients were undertreated, and only half received a CDK4/6 inhibitor (CDK4/6i)-based regimen in the first-line setting. Reasons for undertreatment include concerns about the patient’s age, perceived frailty, and underlying health issues. Aging is a heterogeneous process; older patients must receive individualized treatment that is not based solely on their age but on a comprehensive assessment that objectively assesses their overall health and ability to tolerate treatment. This program is designed to help clinicians assess the fitness of older patients with HR+/HER2– mBC, review the efficacy and safety of CDK4/6i in this patient population, and individualize treatment decision-making appropriately.
