Abstract: Trastuzumab emtansine(T-DM1)is an antibody drug conjugate formed by the conjugation of humanized monoclonal antibody trastuzumab with cytotoxic drug DM1 through a linker,which integrates the targeting antibody and the high efficiency of cytotoxic drugs to kill cancer cells,exerts double anti-tumor effect and reduces the toxicity of conventional chemotherapeutic drugs.Several clinical studies have explored the effectiveness and tolerance of T-DM1 in rescue treatment of advanced HER2 positive metastatic breast cancer and adjuvant and neoadjuvant chemotherapy of early HER2 positive breast cancer,and shown a good clinical application prospects.This article briefly reviews the latest clinical research progress of T-DM1 in HER2 positive breast cancer.

Key words: Trastuzumab emtansine, HER2 positive breast cancer, Mechanisms of action, Clinical trials, Drug resistance mechanism
