紫杉醇治疗上皮性卵巢癌密集型疗法的系统评价

目的系统评价紫杉醇联合铂类治疗上皮性卵巢癌密集型疗法的临床疗效和安全性。方法计算机检索Cochrane临床对照试验资料库（2008年第2期）、MEDLINE（1980年1月～2008年6月）、EMbase（1984～2008年6月）、中国生物医学文献数据库（1980年1月～2008年6月）、CNKI（1980～2008年6月）等，收集有关紫杉醇治疗上皮性卵巢癌密集型疗法与传统疗法的随机对照试验（RCT）。由两名研究者共同完成文献筛选、资料提取并进行质量评价后，采用RevMan5．0软件进行Meta分析。结果最终纳入6篇文献，其中外文3篇、中文3篇，包括572例患者。Meta分析结果显示：①疗效评估：密集型疗法与传统疗法在治疗有效率[RR=1．06，95％CI（0．94，1．20）]、中位生存期、生存率、中位无进展生存时间、中位进展时间方面差异均无统计学意义。②毒副反应：密集型疗法在降低Ⅲ度以上中性粒细胞减少的发生率[RR=0．49，95％CI（0．35，0．69），P〈0．0001]以及Ⅲ度以上神经毒性反应[RR=0．43，95％CI（0．24，0．78），P=0．006]上有明显优势。面色潮红、Ⅲ度以上的呕吐、贫血、白细胞减少、Ⅲ度以上血小板减少以及脱发等方面与传统疗法相比，其差异无统计学意义。结论紫杉醇密集型疗法和传统疗法比较，治疗效果相似，毒副反应基本相近，但能明显降低Ⅲ度以上中性粒细胞减少及Ⅲ度以上神经毒性反应的发生率。因此，密集型疗法是传统疗法良好的替代治疗方案。

Systematic Review of Paclitaxel Intensive Therapy for Ovarian Epithelial Cancer

Objective To evaluate the efficacy and the adverse reactions of intensive therapy compared with conventional therapy. Methods We searched the Cochrane Central Register of Controlled Trials (Issue 2, 2008), MEDLINE (January 1980 to June 2008), EMbase (1984 to June 2008), CBM-disc (January 1980 to June 2008) and CNKI (1994 to June 2008) to get all the randomized control trials (RCTs) about paclitaxel intensive versus conventional therapy for ovarian cancer. We used RevMan 5 to perform meta-analysis. Results Six RCTs involving 572 patients were included. Metaanalysis showed the efficacy of intensive therapy and conventional therapy was similar. There were no significant differences in response rate (RR 1.06, 95%CI 0.94 to 1.20), median survival time, survival rate, median progression free survival and median time to progression between the two groups. When taking safety into consideration, intensive therapy significantly reduced the occurrence of grade Ⅲ or higher neutropenia (RR 0.49, 95%CI 0.35 to 0.69, P<0.000 1) and Grade Ⅲ or higher neuropathy (RR 0.43, 95%CI 0.24 to 0.78, P=0.006). But there were no significant differences between intensive therapy and conventional therapy in flush, grade Ⅲ or higher vomiting, anemia, leucopenia, grade Ⅲ or higher thrombocytopenia and alopecia. Conclusion Paclitaxel intensive therapy has similar efficacy and adverse reactions compared with conventional therapy in ovarian cancer. Above all, intensive therapy can reduce the incidence of grade Ⅲ or higher neutropenia and neuropathy. It is a good substitution for the conventional therapy.
