Triple-negative breast cancer tumors relapse more frequently in spite of good initial response to chemotherapy, and have a worse prognosis than hormone receptor-positive, luminal subtypes. New systemic therapies are urgently needed because hormonal therapies and HER2-targeted agents are ineffective in this group of tumors. Poly (ADP-ribose) polymerase inhibitors, angiogenesis inhibitors, EGFR-targeted agents, and src kinase and mTOR inhibitors are among the therapeutic agents being actively investigated in clinical trials in these patients.
