Objectives  To systematically review the efficacy and safety of docetaxel or epirubicin based regimens in the treatment of advanced gastric cancer. Methods  We searched EMbase, PubMed, The Cochrane Library, Web of Science, CBM, CNKI and WanFang Data from inception to March 2017, to collect randomized controlled trials (RCTs) on docetaxel or epirubicin based regimens in the treatment of advanced gastric cancer. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was performed by using RevMan 5.3 software. Results  A total of 12 RCTs involving 984 advanced gastric cancer patients were included. The results of meta-analysis showed that docetaxel based regimens were superior to epirubicin based regimens in ORR (RR=1.21, 95%CI 1.02 to 1.43, P=0.03), DCR (RR=1.13, 95%CI 1.01 to 1.26, P=0.03), 1-year survival rate (RR=1.26, 95%CI 1.01 to 1.56, P=0.04) and 2-year survival rate (RR=3.03, 95%CI 1.59 to 5.75, P=0.000 7), while there was no statistical difference between two groups in the incidence of grade Ⅲ to Ⅳ adverse events. The results of sensitivity analysis showed that docetaxel based regimens were superior to epirubicin based regimens in 2-year survival rate (RR=2.56, 95%CI 1.06 to 6.19, P=0.04), but there were no statistical differences in ORR (RR=1.13, 95%CI 0.88 to 1.45, P=0.34), DCR (RR=1.02, 95%CI 0.85 to 1.21, P=0.84) and 1-year survival rate (RR=1.29, 95%CI 0.92 to 1.80, P=0.14). The results of sensitivity analysis indicated that the overall outcomes might be affected by the risk bias of included studies. The comparision between docetaxel based regimens and epirubicin based regimens was consistent with the overall outcomes in the incidence of grade Ⅲ to Ⅳ adverse events. Conclusions  Compared with epirubicin based regimens, docetaxel based regimens may have more clinical benefits for advanced gastric cancer patients. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
