ABSTRACT
Objective:To evaluate the efficacy and safety of the combination of apatinib and S-1 for treatment of patients with advanced gastric cancer, in order to provide clinical therapy reference for advanced gastric cancer.Methods:Clinical trials were retrieved from China National Knowledge Infrastructure (CNKI) , Chinese Science and Technology Journal Database (CSTJ) , Wanfang Medical Network, VIP Journal Database (VIP) , China Biomedical Literature Database (CBMdisc) , Cochrane Library, PubMed, etc., searched from Jan. 2010 to Oct. 2019. The experimental group were given apatinib combined with S-1, and the control group received S-1 monotherapy. Two sets of RCT in patients with advanced gastric cancer were collected. Researchers first screened literature, data extraction and to assess the risk of bias, then made Meta analysis with RevMan5.3 software, the test level was α=0.05.Results:A total of 12 Meta analysis of randomized RCT were selected from the group, including 561 cases of patients. The results showed that objective response rate (ORR) and disease control rate (DCR) of the experimental group was higher than those of the control group [ (RD=0.16, 95% CI: 0.08-0.23, P<0.0001; RD=0.21,95% CI: 0.14-0.29, P<0.00001) ]; There was no significant difference in nausea and vomiting, hand-foot syndrome, fatigue, diarrhea, thrombocytopenia, neutropenia, leukopenia, neuro-toxicity and mucositis between the two groups. The rate of hypertension, proteinuria, hemoglobin of the experimental group decrease was higher than that of the control group [ (OR=6.21, 95% CI: 1.92-20.13, P=0.002; OR = 10.57,95% CI: 5.06-22.04, P<0.00001; OR=2.84, 95% CI:1.25-6.48, P=0.01) ]; and there was a significant heterogeneity in hypertension among them ( P=0.008, I 2=63) . Conclusion:Compared with S-1 alone, the treatment effect of S-1 combined with targeted drug apatinib can significantly improve ORR and DCR of patients with advanced gastric cancer.
