Triple-negative breast cancer: current management and future options

Triple-negative breast cancer is a particularly difficult to treat and biologically aggressive disease with limited treatment options. However, a subset of patients with triple-negative tumours may respond to chemotherapy. Therefore, optimisation of chemotherapy regimens may be key in treating triple-negative breast cancer. Emerging treatment approaches include novel chemotherapeutic agents such as the epothilones. The epothilones are a group of novel microtubule-stabilising agents with demonstrated activity in anthracycline-/taxane-resistant triple-negative breast cancer, and ongoing trials are evaluating the combination of epothilones with targeted agents or inclusion of epothilones in novel combination regimens. Other interesting new treatment options include the PARP inhibitors, which are currently in clinical trials for triple-negative breast cancer.
