Abstract
OBJECTIVE: This meta-analysis synthesized the available evidence on the effectiveness and safety of Shenqi Fuzheng injection (SQFZI) combined with chemotherapy for breast cancer. METHOD: A comprehensive systematic literature search was conducted to identify the randomized controlled trials (RCTs) on breast cancer treated by SQFZI in several electronic database up to October 29, 2017. The included RCTs were assessed using the Cochrane Collaboration tool; data were extracted and analyzed via RevMan 5.3 and Stata 13.0 software. RESULTS: A total of 31 eligible RCTs comprising 2543 participants were selected in this present meta-analysis. The results demonstrated that compared with receiving conventional chemotherapy alone, SQFZI treatment combined with chemotherapy was more efficient in improving clinical total effective rate (relative risk [RR] = 1.31, 95% CI 1.19-1.44, P < .00001) and performance status (RR = 2.23, 95% CI 1.88-2.65, P < .00001). Additionally, SQFZI combined with chemotherapy was capable of enhancing immune function and alleviating adverse drug reactions for patients with breast cancer. CONCLUSIONS: The current evidence suggested that using SQFZI as an adjunct treatment to chemotherapy may be preferable for patients with breast cancer compared to chemotherapy alone. Because of the limitations of the quantities and qualities of included RCTs, more well-designed RCTs are needed to further support our conclusion.
