Abstract:
Objective To investigate the efficacy of TTC and FTC regimens as neoadjuvant chemotherapy in breast cancer. Methods Collecting clinical data of 325 patients received neoadjuvant chemotherapy with TIC and FTC regimens from June 2004 to April 2008, among them 138 patients received neoadjuvant chemotherapy with TTC regimen in one group, and 187 patients received neoadjuvant chemotherapy with CTF regimen in the other group. The expression of Topo Ⅱ a in specimen of 325 patients before neoadjuvant chemotherapy were detected by immunohistochemical method. Results Among the 325 cases of neoadjuvant chemotherapy, the overall response rate (RR) was 87.7 % in TIC arm and 67.4 % in FTC arm (P=0.000), but in the group of Topo Ⅱ a(+) Her-2(-), the overall response rate (RR) was 87.8 % in TTC arm and 79.4 % in FTC arm (P=0.266), and in the groups of Topo Ⅱ a(-), there was statistical significance; the pathologic complete response rate (pCR) was 13.7 % in TIC ann and 11.2 % in CTF ann (P=0.491). Conclusion TIC regimen is superior to FTC regimen in the response rate of neoadjuvant chemotherapy, but patients with negative expression of Topo Ⅱ a may get more benefits from 9eoadjuvant taxane and anthracycline chemotherapy.
