赫赛汀联合多西紫杉醇用于局部晚期乳腺癌新辅助化疗近期疗效探讨

目的 探讨赫赛汀联合多西紫杉醇用于局部晚期乳腺癌新辅助化疗的近期疗效及不良反应.方法16例经病理证实为局部晚期乳腺浸润性导管癌患者接受赫赛汀(第1周期8 ms/kg,第2～4周期6ms/ks;静脉注射90 min,第1天)加多西紫杉醇(多西紫杉醇75 ms/m2静脉注射60 min,第2天)术前化疗,3周为1个周期,共4个周期;术前化疗后接受乳腺癌改良根治术或保乳根治术.结果 16例患者总有效率为87.5%,临床完全缓解率为56.3%,病理完全缓解率为25.0%;KPS评分均得到较大改善;主要不良反应为骨髓抑制和胃肠道反应,未出现心脏毒性.结论赫赛汀联合多西紫杉醇用于局部晚期乳腺癌新辅助化疗有较高的有效性和安全性,值得临床进一步探讨,最终结论需大样本的研究结果.

Short-term therapeutic effect of neoadjuvant chemotherapy with herceptin and docetaxel in patients with localized advanced breast cancer

Objective To investigate the efficacy and adverse effect of herceptin combined with docetaxel in patients with localized advanced breast cancer. Methods 16 patients with localized advanced breast cancer were treated with herceptin (8 mg/kg in the first cycle and 6 mg/kg from 2 to 4 cycles,d1) and docetaxel (75 mg/m2 ,d2) for 4 cycles. Three weeks were taken as a cycle. Following chemotherapy, the patients underwent improved radical operation of breast cancer or radical operation of preserving breast. Results The overall response rate (oRR) was 87.5%. The complete clinical remission rate (cCR) was 56. 3%. The complete pathologic remission rate (pCR) was 25.0%. The mainly adverse effects were bone marrow depression and gastrointestinal toxicity. Conclusion The regimen of herceptin combined with docetaxel is effective and can be well-tolerated by patients with localized advanced breast cancer. It shows promising prospect in clinical application.
