Abstract:

Triple-negative breast cancer is one of the subtypes of breast cancer, which exhibits a lack of the expression of estrogen receptor and progesterone receptor and the amplification of human epidermal growth factor receptor 2. Compared with other subtypes, triple-negative breast cancer has a younger onset age, higher degree of malignancy, and worse prognosis, which has always been the focus of clinical and research. Patient-derived xenograft model is established by engrafting tumor tissue or primary cells into immunodeficient mice, which faithfully retains the biological features of the primary tumor. It has been widely used in the study of triple-negative breast cancer. This review describes the application of patient-derived xenograft model in the study of triple-negative breast cancer.

Key words: Triple-negative breast cancer, Patient-derived xenograft model, Animal model
