雷替曲塞联合顺铂化疗恶性胸膜间皮瘤的系统评价

目的系统评价雷替曲塞联合顺铂与其他化疗方案化疗比较,治疗恶性胸膜间皮瘤的有效性和安全性。方法计算机检索Cochrane图书馆、PubMed、EMbase和中国生物医学文献光盘数据库,纳入雷替曲塞联合顺铂与其他化疗方案比较治疗恶性胸膜间皮瘤的随机和半随机试验,检索时间截至2007年3月前。按Cochrane系统评价方法,评价纳入研究的方法学质量,并提取有效数据进行分析。结果仅纳入1个包括250例患者的随机对照试验。雷替曲塞联合顺铂方案与单用顺铂比较能够提高恶性胸膜间皮瘤患者的中位生存期(11.4个月vs8.8个月,P=0.048),且发生3～4级不良反应率与单用顺铂化疗相当。结论目前证据表明,雷替曲塞联合顺铂方案能纳入1个随机对照试验,共250例。提高肿瘤功能状态较好的恶性胸膜间皮瘤患者的生存时间,且不良反应发生率低,但仍需更多临床试验证实其疗效。

Raltitrexed plus Cisplatin for Malignant Pleural Mesothelioma:A Systematic Review

Objective To systematically evaluate the clinical effectiveness and safety of raltitrexed plus cisplatin in the treatment of malignant pleural mesothelioma (MPM) when compared with other chemotherapy regimens. Methods We electronically searched PubMed, Embase, The Cochrane Library and Chinese Biomedicine Database to March, 2007. Randomized controlled trials (RCTs) and quasi-RCTs were identified, and Revman 4.2.10 was applied for statistical analyses. Results One RCT involving 250 patients was included, which compared raltitrexed plus cisplatin versus cisplatin alone in the treatment of MPM. In the intention-to-treat population, the median survival time was statistically longer in the raltitrexed plus cisplatin group as compared to cisplatin alone group. (11.4 versus 8.8 months, P=0.048). The incidence of grade 3/4 toxicities was similar between the two groups. Conclusion The current evidence available showed that, the combination of raltitrexed and cisplatin may prolong the survival time for MPM patients, with a low incidence of grade 3/4 toxicities. However, more high-quality RCTs are required to further define its clinical effectiveness.
