ObjectiveTo evaluate the efficacy and toxicity of TEC and CEF regimen in preoperative chemotherapy for patients with breast cancer. MethodsA total of one hundred breast cancer patients undergoing preoperative chemotherapy were divided into TEC group (n=50) and CEF group (n=50) by the pairgroup method and received surgical therapy after three courses of chemotherapy. The efficacy and toxicity of preoperative chemotherapy of patients in two groups were analyzed. ResultsFour patients with stage ⅢB breast cancer quit from CEF group after two courses of treatment because of the worse satisfaction. Clinical complete remission (cCR) was 7 cases, clinic partial remission (cPR) was 34 cases, stable disease (SD) was 9 cases, therefore, the remission rate (RR) was 82.0% (41/50), and reduction rate of tumor was 64.0% (32/50) in TEC group. cCR was 2 cases, cPR was 32 cases, SD was 12 cases, thus the RR was 680% (34/50), and reduction rate of tumor was 40.0% (20/50) in CEF group. The clinical efficacy and reduction rate of tumor of patients in TEC group were significantly superior than those in CEF group (Plt;0.05). The negative conversion ratio of lymph nodes were 54.1% (20/37) and 57.1% (20/35) in TEC group and CEF group, which was not statistically different (Plt;0.05). The occurrence of hair loss and leukopenia of patients in TEC group were significantly higher than those in CEF group (Plt;0.05), while the differences in thrombocytopenia, low concentration of hemoglobin, nausea, vomiting, diarrhea, cardiac toxicity, and neurotoxicity were not significant (Pgt;0.05). ConclusionTEC regimen is better than CEF regimen in the efficacy and safety of neo-adjuant therapy for patients with breast cancer, and well tolerated.
Objectives To systematically review the efficacy and safety of TE regimen versus CEF regimen for Chinese women with ⅡA to ⅢC stage breast cancer. Methods Databases including PubMed, EMbase, VIP, CNKI, WanFang Data and CBM were electronically searched from inception to December 2016 to collect randomized controlled trials (RCT) on TE regimen versus CEF regimen for Chinese women with ⅡA to ⅢC stage breast cancer. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.3 software. Results A total of 14 RCTs were included. The results of meta-analysis showed that: the complete remission rate (CR) (RR=1.73, 95%CI 1.35 to 2.22, P<0.000 1) and clinical efficacy rate (RR) (RR=1.31, 95%CI 1.22 to 1.42,P<0.000 01) of the TE group were superior to those of the CEF group. But there were no significant differences between two groups in cardiac toxicity, myelosuppression and gastrointestinal reactions. Conclusions TE regimen is superior to CEF regimen in terms of efficacy for the Chinese women with ⅡA to ⅢC stage breast cancer, and there is no difference between the incidence of adverse reactions. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
