摘　　要：目的比较多西他赛联合卡铂（TP）方案与表柔比星联合环磷酰胺序贯多西他赛（EC．T）方案辅助治疗三阴性乳腺癌（TNBC）的Ⅲ期临床研究的安全性。方法2010年1月至2011年9月，经术后病理证实的95例I～Ⅲ期TNBC患者随机分为EC—T组（47例）和TP组（48例）接受术后化疗。EC-T组：环磷酰胺600mg／m2，表柔比星90mg／m2，静脉滴注，第1天，每3周重复，共4个周期；序贯多西他赛80mg／m2，第1天，每3周重复，共4个周期。TP组：多西他赛75mg／m2，卡铂曲线下面积（AUC）=5，静脉滴注，第1天，每3周重复，共6个周期。化疗后根据病情给予辅助放疗。以x2检验比较两组患者不良反应的发生率。结果76例患者可评价不良反应，其中EC-T组37例，中位年龄47岁，绝经前21例（56．8％）；TP组39例，中位年龄46岁，绝经前22例（56．4％）。EC-T组患者均按计划完成化疗，TP组有2例（5．1％）患者因骨髓抑制未完成化疗。在化疗期间，EC-T组和TP组均有9例患者进行剂量调整。76例患者的不良反应以1—2级较常见。EC-T组和TP组患者3～4级脱发的发生率分别为29．7％和10．3％（P=0．033），呕吐的发生率分别为21．6％和7．7％（P=0．085），白细胞减少的发生率分别为54．1％和25．6％（P=0．011），中性粒细胞减少的发生率分别为51．4％和35．9％（P=0．174）。其他3—4级不良反应少见。除周围神经毒性和色素沉着外，其他不良反应均在化疗结束后1个月内恢复。结论EC—T和TP方案辅助治疗可手术TNBC患者的不良反应可以耐受，接受TP方案治疗的患者3～4级脱发和白细胞减少的发生率较低。Objective Triple-negative [ estrogen receptor （ER） -/progesterone receptor （PR） -/ HER2-] breast cancer （TNBC） accounts for ~ 15% of overall breast cancer and associated with a poor prognosis. There is a short of standard adjuvant chemotherapy regimens for TNBC. A number of studies have shown that TNBC might be sensitive to cisplatin and carboplatin on the basis that dysfunction of BRCA1 and its pathway is associated with a specific DNA-repair defect, but data of adjuvant setting about this is limited. Methods From January 2010 to September 2011, 95 early triple-negative breast cancer patients confirmed by pathology were randomly assigned to receive TP （ docetaxel 75 mg/m2, carboplatin AUC = 5, day 1, 21 days a cycle for 6 cycles） or EC-T （epirubicin 90 mg/m2, cyclophosphamide 600 mg/m2,d1, 21days a cycle for 4 cycles, followed by docetaxel 80 mg/m2, d1, 21 days a cycle for 4 cycles） chemotherapy. Adjuvant radiation therapy was given selectively after chemotherapy. Here we report a preliminary safety analysis with the chi-square test. Results Seventy-six out of the 95 patients had completed the chemotherapy and could be assessed for the safety profiles of the regimens. Thirty-seven of them were in the EC-T group with a median age of 47 years, and 21 out of these 37 patients were premenopausal （56.8%）. Another 39 patients came from the TP group with a median age of 46 years, and 22 out of these 39 patientswere premenopausal （ 56.4% ）. All of the 37 patients in EC-T group completed the planned treatment whereas 2 patients of the 39 cases in TP group did not because of bone marrow suppression. During the treatments, 9 patients had dose adjustment in each group. Adverse events of grade 1/2 were common. Specific incidence of adverse events with grade 3/4 in each group was as follows： alopecia, 29.7% vs. 10.3% （P=0.033）, vomiting 21.6% vs. 7.7% （P =0. 085）, leukopenia 54.1% vs. 25.6% （P = 0.011） and neutropenia 51.4% vs. 35.9% （ P = 0. 174）. Other grade 3/4 toxicities were
