Trastuzumab is a monoclonal antibody targeting human epidermal growth factor receptor-2(HER2),which can regulate the expression of HER2 and its downstream signaling function,regulate cell cycle,inhibit tyrosine kinase activity,slow down tumor angiogenesis and regulate tumor immune microenvironment.In HER2-positive breast cancer,trastuzumab is used as a first-line treatment throughout preoperative neoadjuvant therapy and postoperative targeted therapy.However,in recent years,as breast cancer has become the first most frequent tumor in women,the problem of trastuzumab resistance has become more and more common.Studies have shown that tumor microenvironment plays an important role in trastuzumab resistance,which can affect the development and prognosis of HER2-positive breast cancer.This review summarizes the progress of tumor microenvironment in the mechanism of trastuzumab resistance in recent years,emphasizes the role of NK cells,and Outlines the methods to overcome resistance and improve patient prognosis.
