[Targeted based therapies in metastatic breast cancer: future evolution]

Abstract

Research on molecular alteration process mechanisms leading to cancerogenesis permitted the elaboration of many targeted therapies. Some therapeutic classes appeared recently and are currently being tested, including HER-2 dimerization inhibitors. However, most of these therapies are mostly ineffective with monotherapy. Clinical trials are ongoing, testing their efficiency in association with other molecules of the therapeutic arsenal which is available in oncology. Nevertheless, breast cancer remains a pathology life-threatening, most of the time. Within this review will be introduced the most efficient of these targeted therapies, including their eventual association with other cytotoxic molecules.
