Efficacy of Brucea javanica Oil Emulsion Injection Combined with the Chemotherapy for Treating Gastric Cancer: A Systematic Review and Meta-Analysis

OBJECTIVE: This meta-analysis sought to assess the efficacy and safety of Brucea javanica oil emulsion injection (BJOEI) combined with chemotherapy for treating gastric cancer (GC). METHOD: Randomized controlled trials (RCTs) regarding BJOEI to treat GC were searched in PubMed, the Cochrane Library, Embase, the China National Knowledge Infrastructure Database (CNKI), the Wan-Fang Database, China Science and Technology Journal Database (VIP), and the Chinese Biomedical Literature Database (SinoMed) up to January 9, 2017. The clinical total effective rate, performance status, adverse drug reactions (ADRs), and other outcomes were analyzed with Review Manager 5.3 and Stata12.0 software. RESULTS: 13 RCTs involving 912 patients were included in the present meta-analysis. The results demonstrated that, compared with receiving chemotherapy alone, BJOEI combined with chemotherapy was more effective in improving clinical total effective rate (RR = 1.38, 95% CI: 1.22~1.56, P < 0.00001), performance status (RR = 1.63, 95% CI: 1.30~2.04, P < 0.00001), and relieving ADRs such as myelosuppression, neutropenia, thrombopenia, and liver damage. Statistically significant difference was observed between the experimental group and control group. CONCLUSION: The pooled analysis showed that using BJOEI on the basis of the chemotherapy had a remarkable therapeutic effect for patients with GC, whereas more evidence-based medical researches were required to further support our study.
