Objective To systematically review the efficacy and safety of gefitinib versus pemetrexed as second-line treatment for advanced non-small cell lung cancer (NSCLC). Methods Databases 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. Results A 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. Conclusion Gefitinib 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.
