The 2020 ASCO and SABCS meetings provided data that may have important implications in early breast cancer settings. Sara A. Hurvitz, MD, leads a virtual discussion with Kevin Kalinsky, MD, MS, Ruth O’Regan, MD, and Sara M. Tolaney, MD, MPH, in which the panel reviews recent clinical trial data and how new treatment guidance may impact patient outcomes.

The roundtable begins with an overview of data from the monarchE and PENELOPE-B trials and a discussion about the potential role of CDK4/6 inhibition in early HR-positive disease.
