Triple-negative breast cancer represents approximately 10-20% of all breast cancers and is associated with worse prognosis than other subtypes, with a higher risk of recurrence and death than other breast cancer types. This cancer is considered a heterogeneous disease comprising a spectrum of cancers with distinct activated biological pathways, various levels of chemosensitivity and different propensity for metastasis. Currently, chemotherapy represents the mainstay of medical treatment of these patients, because of the absence of well-defined molecular target agent, and we cannot use investigational classifications to determine appropriate systemic therapy outside of clinical trials. The specific adjuvant chemotherapy that may be most effective is still being determined but there is general consensus that regimens containing anthracyclines and taxanes are the standard approach for patient after surgery. Unfortunately, although some patients respond to treatment, other women have a high degree of intrinsic resistance to the same therapy. Moreover, in some studies, the pathological complete response was significantly higher in women treated with platinum-based regimen with respect to those treated with other chemotherapy regimen. The systematic evaluation of the predictive value of genomic alterations is critically important for a better comprehension of this entity and to develop new effective therapeutic strategies. In the future, a personalized therapeutic approach based on biology-oriented characteristics and molecular profiling may be effective for the patients.
