Abstract

Cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors in combination with endocrine therapy are a preferred treatment option for premenopausal and postmenopausal women with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) metastatic breast cancer (mBC). Palbociclib is a potent, first-in-class oral inhibitor of CDK4/6. To provide optimal care to patients with HR+/HER2- mBC receiving palbociclib, advanced practitioners require a thorough understanding of the efficacy and adverse event (AE) profile of palbociclib as well as the diverse characteristics and support needs of patients eligible for palbociclib treatment. This Grand Rounds uses two hypothetical patient scenarios to illustrate core issues in the management of premenopausal and postmenopausal patients receiving palbociclib-based therapy for mBC. In addition to providing an overview of key efficacy and safety data, each case offers practical guidance on providing individualized, patient-centered care, the identification and management of treatment-related AEs, management of concomitant medications, and best practices to promote adherence to therapy.
