Abstract: With the advent of the age of immunotherapy,breast cancer treatment has also opened a new treatment strategy.The application of immune checkpoint inhibitors(ICI)in the treatment of breast cancer has achieved remarkable success in clinical practice.However,because it is only effective for a small number of patients,immunotherapy may lead to the occurrence of immune-related adverse events.Therefore,the patient's treatment options must be optimized through the use of relevant biomarker.Recently,many studies have confirmed that tumor mutational burden(TMB)is an emerging biomarker that can predict the efficacy of breast cancer immunotherapy.The article reviews the predictive value and application status of TMB in immunotherapy for breast cancer patients.

Key words: Breast cancer, Tumor mutational burden, Immunotherapy, Immune checkpoint inhibitor
