ObjectiveTo sort out the key evidence-based data and recent advances in the systemic treatment of advanced triple-negative breast cancer (TNBC), to summarize the therapeutic strategies so as to provide guidance for clinical practice. MethodThe key evidence and research progress on immune checkpoint inhibitors, antibody-drug conjugates (ADCs), poly ADP-ribose polymerase (PARP) inhibitors, anti-angiogenic agents, and novel microtubule inhibitors were summarized. ResultsThe treatment landscape for advanced TNBC has shifted from chemotherapy-centric approaches to biomarker-driven, stratified precision therapy. Based on programmed cell death ligand 1 (PD-L1) expression levels, immune therapy combined with chemotherapy is prioritized. For patients with germline breast cancer gene 1/2 (gBRCA1/2) mutations, PARP inhibitors are recommended. ADCs are suggested for second-line treatment, while novel microtubule inhibitors, either alone or in combination with anti-angiogenic agents, are preferred for later-line therapy to extend patient survival. ConclusionDynamic monitoring of molecular biomarkers such as PD-L1 and gBRCA, combined with sequential or combined “targeted–immunotherapy–ADC” regimens in a “chemotherapy-free” approach, has shown promise in improving overall survival in advanced TNBC.
