Abstract:

Triple negative breast cancer (TNBC) is defined by the absence of three primary growth driver markers in the tumor: ER, PR, and HER-2. Therefore, TNBC is considered as a disease with undefined biological characteristics and high heterogeneity. Among all molecular subtypes, TNBC has the poorest prognosis, and the 5-year survival rate of advanced TNBC patients is about 12%. With the in-depth understanding of the biological characteristics of TNBC, personalized treatment draws more and more attention, thus promoting the continuous transition of TNBC treatment modes towards precision medicine. Precision treatment is to predict the response of certain patient groups to targeted therapy based on expression of identified biomarkers, Currently, the focus of clinical researches has shifted to identifying biomarkers with potential drug targets, such as immune checkpoint inhibitors, targeted therapeutic drugs and antibody-drug conjugates, which have become indispensable in the decision-making in the treatment. With more precise classification of TNBC subtypes and continuous improvement of treatment strategies, patients with advanced TNBC are expected to have more accurate diagnosis and precise treatment.

Key words: Breast neoplasms, Immunotherapy, Antibody-drug conjugates
