摘要 目的:比较体部立体定向放疗(stereotactic body radiotherapy,SBRT or stereotactic ablative radiothera-py,SABR)与手术治疗早期非小细胞肺癌(non-small cell lung cancer,NSCLC)的疗效。方法通过计算机检索Cochrane图书馆、PubMed、Medline、中国期刊全文数据库(CNKI)、中国生物医学文献数据库(CBM)、万方数据库,收集国内外公开发表关于 SBRT与手术治疗早期 NSCLC的相关文献,采取双人平行评价的方法对收集的文献进行评价,提取资料并交叉核对,应用统计软件RevMan5.2进行Meta分析。结果筛查后共纳入4项回顾性研究,均为英文文献,共1265个患者,其中手术治疗914例(手术组),SBRT351例(SBRT组),根据研究内容将两组生存率分为 A、B、C 3组进行 Meta分析,4项研究综合评价2种治疗方法生存率作为 A组,2项研究两组病例进行了1∶1配对,两组在年龄、合并症评分及肿瘤分期等因素方面差异无统计学意义,为 B组;另外2项研究对两组病例也进行了1∶1配对,但两组在年龄、合并症及肺功能等因素方面差异有统计学意义,且手术组优于 SBRT组,为 C组。A组:1、2、3年总生存率差异均有统计学意义(P <0.0001~0.00001),手术组优于 SBRT组;B组:1、2年总生存率差异无统计学意义(P =0.35;P =0.29),3年总生存率差异有统计学意义(P =0.02),手术组优于 SBRT组;C组:1、2、3年总生存率差异均有统计学意义(P <0.01~0.00001),手术组优于 SBRT组。2项研究中两组肿瘤特异性生存率差异无统计学意义(P =0.46,P =0.19)。结论由于两组间存在年龄、肺功能及合并症等方面的差异,不能明确得出手术组优于 SBRT组的结论,但两组间肿瘤特异性生存率无差异,两组疗效的比较还需要临床随机对照试验来进一步研究。 Objective This research aimed to compare the efficacy of SBRT and surgical treatment of early-stage NSCLC.Methods By searching the Cochrane Library,PubMed,Medline,Chinese Journal Full-text Database (CNKI),Chinese Biomedical Literature Database (CBM)and Wan Fang DATA,the published literature about SBRT and surgical treatment of early-stage NSCLC at home and abroad were reviewed for extraction and evaluation by double parallel method and cross checking,and the meta-analyses were con-ducted by RevMan 5 .2 software.Results 4 retrospective English studies involving 1 2 6 5 cases were includ-ed,with 914 surgical treatment cases and 351cases SBRT.Group A,B,C were divided in surgery group and SBRT group:Group A with 4 studies on comprehensive evaluation on the survival rate;Group B with two studies matched by 1∶1 in surgery group and SBRT group,with no statistical significance in age,co-morbidity score and tumor staging;Group C with the other two studies matched by 1∶1 in surgery group and SBRT group,with statistical significance in age,comorbidity score and pulmonary function.Group A:1-year,2-year and 3-year overall survival differences had statistical significance (P〈0.000 1;P〈0.000 01;P 〈0.000 01),with higher survival rate in surgery group than in SBRT group;Group B:1-year,2-year overall survival differences were not statistically significant (P=0.35;P=0.29),but 3-year overall surviv-al difference was statistically significant (P =0.02),with higher survival rate in surgery group than in SBRT group;Group C:1-year,2-year and 3-year overall survival differences had statistical significance (P=0.002;P 〈0.000 01;P 〈0.000 01),with higher survival rate in surgery group than in SBRT group;There was no statistically significant difference in tumor-specific survival rate in two groups (P=0.46,P=0.19).Conclusion Due to the differences in age,pulmonary function and complications between two groups,the better results of Surgery group over SBRT group were not definitely decided in the overall sur-vival,but with no difference in the tumor-specific survival rate between the two groups.Therefore,the curative effect of two groups in randomized controlled trials needs to be further explored.
