Neoadjuvant Chemotherapy of 6 Cycles vs 8 Cycles in Node Positve Breast Cancer

Summary

Various regimens and schedule as neoadjuvant chemotherapy regimens were investigated and sequential treatment of anthracyclines followed by taxanes, which has shown superior pathologic complete respone (pCR) rate (NSABP-B27 study) is widely used until now. Considering the proven efficacy and tolerable toxicity of 3 cycles of FEC followed by 3 cycles of Docetaxel (FEC3-D3) compared to FEC 6 cycles in adjuvant chemotherapy (PACS 01 trial), use of FEC3-D3 regimen in neoadjuvant setting will be feasible with acceptable efficacy and further reduce the duration of neoadjuvant chemotherapy.
