Managing CDK4/6 Inhibitor Toxicities and Encouraging Adherence
Author(s)Kevin Kalinsky, MD, MS, Virginia Kaklamani, MD
Panelists discuss how common adverse events (AEs) with CDK4/6 inhibitors in HR+/HER2- early breast cancer (eBC) vary based on treatment and patient population, with strategies for mitigating toxicities, adjusting dosing, and monitoring labs to ensure treatment continuation; they also address approaches to dose reductions, promoting treatment adherence, educating patients about toxicity management, and balancing efficacy, quality of life, and side effect risks, particularly for high-risk patients with no or low nodal involvement.
