Abstract:

Traditional treatments for breast cancer include surgery, radiotherapy and chemotherapy. Targeted therapy has become an important treatment method for breast cancer because of its strong specificity and low toxicity. Human epidermal growth factor receptor-2 (HER-2) positive breast cancer has strong invasiveness and poor prognosis. The advent of trastuzumab improves the prognosis of HER-2-positive breast cancer. Since then, a series of anti-HER-2 targeted therapies have been used for clinical research and treatment, including pertuzumab, lapatinib, lenatinib, pyrotinib and ado-trastuzumab emtansine. This article reviews the current status of anti-HER-2 drugs with different mechanisms of action in the targeted therapy of HER-2-positive breast cancer.

Key words: Breast neoplasms, Targeted therapy, Receptor, epidermal growth factor, HER-2
