Evid Based Complement Alternat Med. 2019 ;2019:2417418. Epub 2019 Dec 17. PMID: 31929811
Objective: In China, ginsenoside Rg3 is often used in combination with chemotherapy to treat digestive system cancer. We here performed a meta-analysis and systematic review to provide a much needed high-quality evaluation of the efficacy and safety of ginsenoside Rg3 combined with chemotherapy in these cancers.
Materials and Methods: The PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang, and Weipu (VIP) databases were searched. All randomized controlled trials (RCTs) concerning ginsenoside Rg3 combined with chemotherapy for digestive system cancer were selected. Dichotomous data were expressed as odds ratios (ORs) with 95% confidence intervals (CI). The methodological quality of the included studies was evaluated according to the Cochrane evidence-based medicine system, and the statistical analyses were performed with Review Manager 5.3 and STATA 12.0 software. In addition, the Grades of Recommendation Assessment, Development and Evaluation (GRADE) approach was used to rate the quality of the evidence. Trial sequential analysis (TSA) was used to evaluate information size and treatment benefits.
Results: A total of 18 trials comprising 1531 patients were included in this study. The results revealed that the trials were of sufficient standard to draw reliable conclusions that ginsenoside Rg3 combined with chemotherapy could improve the objective response rate (ORR; OR 2.17, 95% CI 1.72-2.73), disease control rate (DCR; OR 2.83, 95% CI 2.02-3.96), 1-year survival rate (SR; OR = 2.33, 95% CI = 1.24-4.37), Karnofsky Performance Scale (KPS; OR 2.67, 95% CI 1.76-4.03), gastrointestinal dysfunction (OR 0.44, 95% CI 0.31-0.61), and the decline of leucocyte count (OR 0.28, 95% CI 0.21-0.38).
Conclusion: Ginsenoside Rg3 combined with chemotherapy can improve the clinical efficacy and alleviate treatment-induced side effects for digestive system cancer.
