Regimen of Choice of Triple Negative Breast Cancer

  • The regimen of choice for a locally advanced triple negative breast cancer is:
    • Doxorubicin and cyclophosphamide every 2 weeks cycle with growth factor support followed by taxane chemotherapy
  • Neoadjuvant chemotherapy is often given in early stage triple negative breast cancers (> 2 cm or lymph node positive):
    • It has the benefit of increased rates of breast conservation as well as the prognostic value of assessing tumor response to systemic therapy
