Selecting Between CDK4/6 Inhibitors in Advanced HR+/HER2- Breast Cancer


Patients diagnosed with advanced hormone receptor–positive (HR+) and human epidermal growth factor receptor 2–negative (HER2-) breast cancer have significantly improved outcomes with the combination of a cyclin-dependent kinase (CDK) 4/6 inhibitor and endocrine therapy compared with endocrine therapy alone.

Dr Sara Hurvitz, director of the Breast Cancer Clinical Trials Program at UCLA, discusses the efficacy, tolerability, and patient quality-of-life factors to consider when deciding which of the three available CDK4/6 inhibitors — palbociclib, ribociclib, or abemaciclib — is appropriate for your patient in the frontline setting.

Reporting on data from the ongoing MONALEESA, MONARCH, and PALOMA trials, Dr Hurvitz spotlights the differences and similarities between agents that may help steer treatment decisions for pre- or perimenopausal patients
