Updated results from the EMILIA and TH3RESA trials in patients with advanced-stage HER2-positive breast cancer confirm the overall survival benefit and favourable safety profile of T-DM1 after prolonged follow-up durations. The efficacy of T-DM1 as a second or later line of treatment indicates that HER2 is a relevant therapeutic target throughout the course of the disease.
