Abstract
Metastatic triple-negative breast cancer (mTNBC) is characterized by an aggressive course and previously limited treatment options. However, in recent years, the treatment paradigm has undergone revolutionary changes, shifting from non-specific chemotherapy to a personalized, biomarker-based approach. This review provides a detailed analysis of current strategies for the diagnosis and treatment of mTNBC. The critical importance of comprehensive molecular testing, including determination of PD-L1 status, germline mutations in the BRCA1/2 genes, and HER2 expression (including HER2-low status) for choosing the optimal strategy is emphasized. This article puts focus on the strategic sequencing of different classes of targeted agents, taking into account their mechanisms of action and application sites. The article provides not only information on available options but also a practical algorithm for decision-making based on the latest evidence-based medicine and a clear hierarchy of biomarkers.
