ObjectiveTo systematically review the efficacy and safety of gefitinib versus pemetrexed as second-line treatment for advanced non-small cell lung cancer (NSCLC). MethodsDatabases including PubMed, The Cochrane Library (Issue 4, 2016), EMbase, CNKI, VIP and WanFang Data were searched to collect randomized controlled trials (RCTs) about gefitinib versus pemetrexed as second-line treatment for advanced NSCLC from inception to April 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed by using RevMan 5.3 software. ResultsA total of 11 RCTs involving 1 005 patients were finally included. The results of meta-analysis showed that: the rate of progression free survival (PFS) in the gefitinib group was superior to the pemetrexed group (HR=0.59, 95%CI 0.47 to 0.73, P<0.000 01). However, there were no significant differences between two groups in overall response rate (RR=1.28, 95%CI 0.86 to 1.90, P=0.22), disease control rate (RR=0.92, 95%CI 0.77 to 1.12, P=0.41) and the rate of overall survival (HR=0.75, 95%CI 0.56 to 1.01, P=0.05). The incidences of skin rash (RR=8.72, 95% CI 3.65 to 20.84, P<0.000 01) and diarrhea (RR=2.87, 95% CI 1.29 to 6.38, P=0.01) were significantly higher, but the incidences of neutropenia (RR=0.12, 95%CI 0.05 to 0.26, P<0.000 01) and fatigue (RR=0.46, 95%CI 0.30 to 0.72, P=0.000 6) were lower in the gefitinib group than those in the pemetrexed group. ConclusionGefitinib shows more superiority to pemetrexed, and it can be used as the second-line drug for advanced NSCLC． Due to the limited quality and quantity of included studies, more high quality studies are needed to verify the above conclusion.
ObjectiveTo systematically review the efficacy and safety of intrapleural injection of endostar combined with cisplatin in treatment of non-small cell lung cancer (NSCLC) with malignant pleural effusion. MethodsDatabases including PubMed, The Cochrane Library (Issue 2, 2016), EMbase, Web of Science, CNKI, VIP and WanFang Data were searched to collect randomized controlled trials (RCTs) about endostar combined with cisplatin for NSCLC with malignant pleural effusion from inception to February 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed by using RevMan 5.3 software. ResultsA total of 10 RCTs involving 610 patients were finally included. The results of meta-analysis showed that: The overall response rate and the improvement rate of quality of life in the endostar combined with cisplatin group were higher than that of the cisplatin alone group (RR=1.71, 95%CI 1.49 to 1.95, P<0.00001; RR=1.68, 95%CI 1.44 to 1.96, P<0.00001, respectively). However, There were no significant differences between two groups in incidence of gastrointestinal reaction, incidence of leucopenia and incidence of thrombocytopenia (all P values>0.05). ConclusionCompared with cisplatin, intrapleural injection of endostar combined with cisplatin can improve the overall response rate and improve the quality of life of NSCLC patients with malignant pleural effusion. Due to the limited quality and quantity of included studies, more high quality studies are needed to verify the above conclusion.
