Along with the Oncology Brothers, Paolo Tarantino, MD, elaborates on results from an analysis of data from the EMERALD study that were reported at the San Antonio Breast Cancer Symposium (SABCS) 2022. This analysis identified duration of prior CDK4/6 inhibitor therapy as a potential surrogate marker for endocrine sensitivity, and discusses how these findings could help guide patient selection for elacestrant.
