文摘背景与目的越来越多的胸科医生选择电视辅助胸腔镜手术(video-assisted thoracoscopic surgery,VATS)来治疗早期非小细胞肺癌(non-small cell lung cancer,NSCLC)。目前,仍然没有随机试验来比较VATS和体部立体定向放疗(stereotactic body radiotherapy,SBRT)的临床疗效。为此,在本meta分析中,我们比较了电视辅助胸腔镜手术和体部立体定向放疗在治疗早期NSCLC患者过程中的疗效,以期为今后对此两种疗法的选择提供参考。方法系统地检索5个主要的医学期刊数据库:中国知网、维普网、PubMed、Embase和ISI web of science,收集时间涵盖2010年1月-2016年2月的应用电视辅助胸腔镜手术和体部立体定向放疗治疗早期NSCLC的所有文献。最后,纳入了拥有足够患者数量和放疗剂量的原创中英文研究成果。在校正了中位年龄和可手术患者人数之后,应用多变量随机效应模型比较了电视辅助胸腔镜手术和体部立体定向放疗治疗后早期NSCLC患者的总生存率和无疾病生存率。结果纳入相同时期的14个电视辅助胸腔镜手术研究成果(包含3,482个患者)和19个体部立体定向放疗研究成果(包含3,997个患者)。VATS组中位年龄和随访时间分别为64岁和43.4个月,SBRT组中位年龄和随访时间分别为74岁和29.5个月。VATS组校正前1年、2年、3年、5年平均总生存率分别为93.5%、84.9%、77.0%、76.3%。SBRT组校正前1年、2年、3年、5年平均总生存率分别为89.0%、73.3%、59.0%、36.7%。VATS组校正前1年、2年、3年、5年平均无病生存率分别为93.6%、88.6%、85.6%、75.6%。SBRT组校正前1年、2年、3年、5年平均无病生存率分别为79.3%、72.1%、64.9%、58.9%。然而,以中位年龄和可手术程度进行校正之后,预期VATS组1年、2年、3年、5年总生存率为94%、92%、84%、71%,预期SBRT组1年、2年、3年、5年总生存率为98%、95%、87%、83%。预期VATS组1年、2年、3年、5年无病生存率为97%、94%、85%、75%,预期SBRT组1年、2年、3年、5年无病生存率为88%、81%、74%、63%。结论在校正前,施以体部立体定向放疗的患者临床表现(总生存率和无病生存率)并不如施以电视辅助胸腔镜手术的患者。但考虑到年龄与可手术程度,施以体部立体定向放疗的患者年龄偏大,可手术程度偏低。以年龄和可手术程度进行校正后,我们发现两种疗法治疗早期NSCLC的总生存率和无病生存率并没有显著区别。
