Breast cancer is the most common malignant tumor in the world. Endocrine therapy is an important treatment for HR positive breast cancer, and its drugs are mainly divided into premenopausal estrogen receptor antagonists and postmenopausal aromatase inhibitors, but drug resistance has become a major challenge in endocrine therapy for breast cancer. This article reviews the drug resistance mechanism and the latest research results of endocrine therapy in premenopausal and postmenopausal breast cancer from the aspects of gene regulation, estrogen and coregulatory cofactor, growth factor signal pathway, cell cycle regulation,autophagy and apoptosis, non-coding RNA regulation, immune surveillance, etc., in order to provide a new basis for clinical solution of endocrine therapy resistance in breast cancer.
