Preclinical data demonstrate in vitro synergy for combinations of docetaxel (Taxotere) and cyclophosphamide. As single agents, both drugs have proven highly active against breast cancer, and the activity of the combination has been confirmed by several phase II studies. More recently, it has proven adjuvant efficacy on par with anthracycline containing regimen in a trial to directly compare AC to Taxotere/Cytoxan (TC) as adjuvant treatment in breast cancer. This recent trial showed that TC improves disease-free survival compared with AC for the treatment of adjuvant breast cancer. Although cardiac side effects were not presented, the researcher noted that TC does not appear to have the cardiotoxicity issues associated with AC, which is a very important issue for some patients. NCCN considers TC an appropriate regimen for adjuvant treatment for breast cancer. and NCCN 2012 lists this regimen on p. BINV-K.However, NCCN does not list it for metastatic disease.
