[摘要] 目的 系统评价125I粒子植入放射治疗联合化疗与单纯化疗在晚期非小细胞肺癌(NSCLC)中的疗效与安全性。方法 检索PubMed、EMBASE、The Cochrane Library、中國生物医学文献数据库(CBM)及中国期刊全文数据库(CNKI)等电子数据库,检索日期为数据库建立至2015年5月。纳入125I粒子植入放射治疗联合含铂化疗方案治疗晚期NSCLC的随机对照试验(RCT),并用RevMan 5.3统计软件进行Meta分析。结果 按照标准共纳入9项研究,包括723例晚期NSCLC患者。Meta分析结果显示:与单纯化疗相比,125I粒子植入联合化疗组治疗晚期NSCLC的有效率(OR=4.59,95%CI:3.24~6.51,P < 0.05),临床获益率(OR=4.01,95%CI:2.32~6.92,P < 0.05),1年生存率(OR=2.60,95%CI:1.45~4.67,P < 0.05)均显著提高,同时不显著增加重度白细胞减少发生率(P > 0.05)。结论 在晚期NSCLC的治疗中,125I粒子植入放疗联合含铂化疗较单纯化疗可提高疗效,同时具有良好的安全性。

[Abstract] Objective To systematically evaluate the clinical efficacy and safety of 125I seed implantation combined with platinum-based chemotherapy and chemotherapy alone in advanced non-small cell lung cancer (NSCLC). Methods The following databases such as PubMed, EMBASE, The Cochrane Library, Chinese Biomedical Literature Database (CBM), and China Academic Journal (CNKI) were retrieved from the time of the database established to May 2015. Randomized controlled clinical trials (RCTs) that comparing the 125I seed implantation combined with platinum-based chemotherapy versus chemotherapy alone in recurrent advanced NSCLC were included and RewMan 5.3 software was used to perform Meta-analysis. Results 9 RCTs involoving 723 patients with advanced NSCLC were adopted according to the inclusion criteria. The results of Meta-analysis showed that compared to chemotherapy group, 125I seed implantation combined with platinum-based chemotherapy could significantly improve the response rate (OR= 4.59, 95%CI: 3.24-6.51, P < 0.05), clinical benefit rate(OR=4.01, 95%CI:2.32-6.92, P < 0.05), and 1-year survival rate (OR=2.60, 95%CI: 1.45-4.67, P < 0.05) in advanced NSCLC, without significantly increase the incidence of severe leukocytopenia (P > 0.05). Conclusion In the treatment of advanced NSCLC, the efficacy of 125I seed implantation combined with platinum-based chemotherapy is better than chemotherapy alone, with tolerable safety.

肺癌是我国最常见的恶性肿瘤之一,其中约80%为非小细胞肺癌(NSCLC),70%~80%的NSCLC患者确诊时已为晚期。近年来的临床研究证实,治疗晚期NSCLC的关键在于改善病情,防治远处转移[1]。目前,晚期NSCLC的治疗仍以全身性化疗为主,其疗效对患者的生存时间及质量至关重要。以化疗为基础,联合局部放疗是一种有效的治疗策略。传统体外放射治疗时,其放疗剂量多受限于正常肺组织和周围重要器官以及肿瘤照射体积等因素。125I放射粒子植入可大幅度提高肺癌局部放疗剂量[2]。关于125I粒子植入放射治疗联合化疗治疗晚期NSCLC的临床效果及安全性的临床研究可见报道[4-20],但无相关循证医学证据。本研究以循证医学为指导,对125I粒子植入放射治……
