摘要 目的:评价放疗联合替莫唑胺治疗与单纯放疗相比,治疗新诊断的多形性成胶质细胞瘤(glioblastoma multiforme,GBM)的有效性及安全性。方法:计算机检索PubMed(1966年1月-2009年12月)、EMBASE(1974年1月-2009年12月)、Cochrane图书馆(2009年第4期)、中国期刊全文数据库(1994年1月-2009年12月)、中国生物医学文献数据库(1978年1月-2009年12月)、中文科技期刊全文数据库(1989年1月-2009年12月)和万方数据库(1997年1月-2009年12月)。纳入放疗联合替莫唑胺治疗新诊断的GBM的临床随机对照试验(randomized controlled trial,RCT),由2名研究者独立进行资料提取和质量评价,纳入文献的方法学质量分析依据Cochrane评价手册5.0.0随机对照试验质量评价标准。采用RevMan5.0软件进行meta分析。结果:最终纳入5个RCT,共包括896例患者。Meta分析结果显示,与单纯放疗相比,放疗联合替莫唑胺治疗可以提高新诊断GBM患者18个月总生存率(overall survival,OS)[相对危险比为2.46(95%的可信区间:1.115.46)]和24个月OS[相对危险比为2.88(95%的可信区间:1.954.25)],改善6个月无进展生存期(progression-free surviv-al,PFS)[相对危险比为1.48(95%的可信区间:1.221.78)]、12个月PFS[相对危险比为3.07(95%的可信区间:2.174.34)]、18个月PFS[相对危险比为4.71(95%的可信区间:2.518.84)]和24个月PFS[相对危险比为7.47(95%的可信区间:2.6720.94)],并改善6个月肿瘤进展时间(time to progression,TTP)[相对危险比为1.51(95%的可信区间:1.072.13)]和12个月TTP[相对危险比为3.91(95%的可信区间:1.599.61)]。放疗联合替莫唑胺治疗引发的34级白细胞减少[相对危险比为4.31(95%的可信区间:0.7724.31)]、34级血小板减少[相对危险比为4.03(95%的可信区间:0.7023.34)]和4级中性粒细胞减少[相对危险比为2.79(95%的可信区间:0.1267.10]与单纯放疗相比,差异无统计学意义。结论:放疗联合替莫唑胺治疗可以提高新诊断GBM患者的18和24个月OS,改善6、12、18和24个月PFS以及6和12个月TTP。因此,放疗联合替莫唑胺治疗是目前术后治疗新诊断GBM的一种较为合理而有效的综合治疗手段。 Objective:To assess the effectiveness and safety of radiotherapy combined with TMZ(temozolomide)for newly diagnosed GBM(glioblastoma multiform)compared with single radiotherapy.Methods:Computer retrieved was conducted to search for relevant RCTs(randomized controlled trails)in Cochrane Library(Issue 4,2009),PubMed(Jan 1966-Dec 2009),EMBASE(Jan 1974-Dec 2009),Chinese Biomedical Literature Database(CBM,Jan 1978-Dec 2009),Chinese Scientific Journals Full Text Database(CSJD,Jan 1989-Dec 2009),China Journal Full Text Database(CJFD,Jan 1994-Dec 2009)and Wanfang Database(Jan 1997-Dec 2009).Two researchers assessed the quality of included trials and extracted data independently.The quality of included studies was critically evaluated and the data were analyzed by using the Cochrane Collaboration’s RevMan 5.0 software.Results:A total of five RCTs including 896 patients were involved in this meta-analysis.The results showed that radiotherapy combined with TMZ in newly diagnosed cases can raise the 18-month OS(overall survival)[RR(risk ratio)=2.46,95% CI(confidence internal):1.11-5.46] and 24-month OS(RR = 2.88,95% CI:1.95-4.25)compared with radiotherapy alone,and improve the 6-month PFS(progression-free survival)(RR =1.48,95% CI:1.22-1.78),12-month PFS(RR =3.07,95% CI:2.17-4.34),18-month PFS(RR =4.71,95% CI:2.51-8.84)and 24-month PFS(RR =7.47,95% CI:2.67-20.94),as well as improve 6-month TTP(time to progression)(RR = 1.51,95% CI:1.07-2.13)and 12-month TTP(RR = 3.91,95% CI:1.59-9.61).There were no differences of incidences of grade 3-4 leukopenia(RR = 4.31,95% CI:0.77-24.31),grade 3-4 thrombocytopenia(RR = 4.03,95% CI:0.70-23.34)and grade 4 neutropenia(RR = 2.79,95% CI:0.12-67.10)between radiotherapy plus TMZ arm and radiotherapy alone arm.Conclusion:Radiotherapy combined with TMZ can raise the OS at 18 and 24 months,increase the PFS at 6,12,18 and 24 months,and improve TTP at 6 and 12 months.Treatment of radiotherapy combined with TMZ is more appropriate and effective than radiotherapy alone for newly diagnosed GBM after operation.
