目的 评价卡培他滨+伊立替康与氟尿嘧啶/醛氢叶酸（5-FU/LV）+伊立替康治疗转移性结直肠癌的有效性和安全性。 方法 计算机检索PubMed、CENTRAL、Embase、中国生物医学数据库、中国期刊全文数据库、维普数据库和万方数据库，检索时间均从建库至2011年9月。对符合纳入标准的随机对照试验进行质量评价和Meta分析。 结果 纳入3个随机对照试验，共计419例患者，卡培他滨+伊立替康在中位生存期、完全缓解率[RR=1.58，95%CI（0.27，9.11），P=0.61]、部分缓解率[RR=0.86，95%CI（0.68，1.09），P=0.20]、总有效率[RR=0.88，95%CI（0.71，1.09），P=0.26]上表现出与5-FU/LV+伊立替康相似的效果，安全性方面卡培他滨+伊立替康有较高的Ⅲ/Ⅳ级恶心[RR=1.92，95%CI（1.05，3.54），P=0.04]、腹泻[RR=3.23，95%CI（2.14，4.89），P＜0.000 01]发生风险和较低的Ⅲ/Ⅳ级中性粒细胞减少[RR=0.72，95%CI（0.53，0.98），P=0.04]发生风险。 结论 根据当前现有证据，5-FU/LV+伊立替康可能较卡培他滨+伊立替康更为有利于转移性结直肠癌患者的治疗，但仍需结合临床实际情况进行化疗方案的优选。
ObjectiveTo systematically review the efficacy and safety of crizotinib in the treatment of non-small cell lung cancer (NSCLC).MethodWe electronically searched databases including the Cochrane Library (Issue 5, 2017), PubMed, Embase, China Biology Medicine Database, China National Knowledge Internet Database, VIP Database and Wangfang Data from the establishment to May 2017. The randomized controlled trials (RCTs), non-RCTs, case series and case reports on crizotinib for NSCLC were included. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, assessed the methodological quality of included studies, then make Meta-analysis and descriptive analysis.ResultA total of 15 studies were included, including 4 RCTs, 1 non-RCT, 4 case series and 6 case reports. The results indicated that the progression-free survival time of crizotinib group was 8 months, which was better than chemotherapy group (4.6 months). The results of Meta-analysis showed that the response rate in the crizotinib group was higher than that in the chemotherapy group [RR=2.35, 95%CI (1.59, 3.46), P<0.000 1]. The one year survival rate in the crizotinib group was 74.5%-78.6%. The incidences of adverse reactions including dysopsia, dysgeusia, diarrhea, vomiting, constipation, transaminase lifts, upper respiratory tract infection, edema and dizziness in the crizotinib group were higher than those in the chemotherapy group (P<0.05), while the incidences of adverse reactions including leukopenia, thrombocytopenia, alopecia and fatigue in crizotinib group were lower than those in the chemotherapy group (P<0.05). Subgroup analysis under precision treatment showed the progression-free survival time of anaplastic lymphoma kinase (ALK)-positive group was 8 months, and it was longer than ALK-negative group of 4 months.ConclusionsBased on current evidence, crizotinib is better than chemotherapy for NSCLC. Due to limited quality of the included studies, the above conclusion needs to be verifed by more high quality studies.
