Patient‐reported outcomes from EMILIA, a randomized phase 3 study of trastuzumab emtansine (T‐DM1) versus capecitabine and lapatinib in human epidermal growth factor receptor 2–positive locally advanced or metastatic breast cancer

Abstract

Together with the EMILIA primary data, these results support the concept that T-DM1 has greater efficacy and tolerability than capecitabine plus lapatinib, which may translate into improvements in health-related quality of life.
