摘要
为评价直肠癌术后局部复发再治疗采用单纯手术与手术联合放疗及单纯放疗的有效性,本研究通过计算机检索Pub Med、EMBASE、Cochrane Library、中国生物医学文献数据库、中国期刊全文数据库、中文科技期刊全文数据库等,并辅以手工检索和其他检索,按纳入标准全面搜集有关单纯手术、手术联合放疗及单纯放疗治疗直肠癌术后局部复发的随机对照研究、半随机对照研究、前赡性及回顾性队列研究,检索截至2013年6月。按照Cochrane系统评价手册5.0.2质量评价标准,由2位研究者独立对纳入研究进行方法学质量评价,并进行资料提取,采用RevMan5.0软件进行Meta分析,计数资料采用相对危险度(RR)为疗效分析统计量;计量资料采用加权均数差(WMD)。结果共纳入10个对照试验(983例患者)。Meta分析结果显示,单纯手术组与单纯放疗组相比,1、3、5年总生存率比较差异均有统计学意义(Pd0.05),其RR(95%可信区间,CI)分别为1_20(1.04,1.39)、1.85(1.43,2.38)和2.52(1.66,3.83);单纯手术组与手术联合放疗组相比,1、3年总生存率比较差异无统计学意义(P〉0.05),5年总生存率比较差异有统计学意义(P〈0.05),其RR(95%CI)分别为0.95(0.84,1.08)、1.15(0.94,1.41)和1.55(1.09,2.21);手术联合放疗组与单纯放疗组相比,1、3、5年总生存率差异均有统计学意义(P〈0.05),其RR(95%CI)分别为1.30(1.11,1.51)、1.72(1.32,2.25)和1.72(1.07,2.78)。结果表明,手术联合放疗在提高直肠癌术后复发患者的生存率,尤其是远期生存率方面优于单纯手术及单纯放疗,单纯手术疗效优于单纯放疗。
Abstract In order to assess the efficacy of surgery alone versus surgery added radiotherapy or radiotherapy alone for postoperative local recurrence of rectal cancer,authors searched all the randomized controlled tri- als(RCTs),quasi-RCTs(q-RCTs), prospective and retrospective cohort study about surgery alone versus surgery added radiotherapy or radiotherapy alone for postoperative local recurrence of rectal cancer in PubMed, Excerpt Medica Database(EMBASE), Cochrane Library, Chinese Biomedical Literature Database (CBM) ,China Journal Full-text Database(CJFD),Chinese science and techndogy Journal Full-text Data- base(CSJFD),assisted manual retrieval and other retrieval methods up to June 2013~also evaluated the methodological quality of included studies by handbook 5.0.2 of Cochrane collaborate.Two researchers con- ducted methodology quality evaluation of inductive research data independently and data extraction. The statistical Meta analysis was performed by RevMan5.0 software.Relative risk (RR) was used in count data to make efficacy analysis statistical value, measurement data used weighted mean difference (WMD).As re- suits,ten studies involved 983 patients were included. Meta-analysis shows:there is statistics difference be- tween the two groups in 1,3,5-year overall survival(OS)( P 〈0.05),the RR(95% confidence interval,CI) respectively are 1.20 ( 1.04,1.39), 1.85 ( 1.43,2.38), 2.52 (1.66,3.83) ; there is no statistics difference between surgery versus surgery added radiotherapy in 1,3-year OS( P 〉0.05),and there is statistics difference be- tween the two groups in 5-year OS( P 〈0.05),the RR(95%CI) respectively are 0.95(0.84,1.08),1.15(0. 94,1.41), 1.55 (1.09,2.21) ;there is statistics difference between surgery added radiotherapy versus surgery in 1,3,5-year OS,the RR(95%CI) respectively are 1.30(1.11,1.51),1.72(1.32,2.25),1.72(1.07,2.78).A- bove data suggest that surgery added radiotherapy is a more efficient agent for postoperative local recur- rence of rectal cancer, especially postoperative local recurrence of in the long-term efficacy; surgery is rectal cancer. more effective than radiotherapy for
