Abstract BACKGROUND: Platinum-based chemotherapy has been a standard therapy for advanced non-small cell lung cancer (NSCLC), but it has high toxicity. In China, Shenqi Fuzheng, a newly developed injection concocted from Chinese medicinal herbs has been reported that may increase efficacy and reduce toxicity when combined with platinum-based chemotherapy, but little is known about it outside of China. The aim of this study was to systematically review the existing clinical evidence on Shenqi Fuzheng Injection(SFI) combined with platinum-based chemotherapy for advanced NSCLC. METHODS: Pubmed, Cochrane Library, EMBASE, CNKI, and CBM search were organized for all documents published, in English and Chinese, until April 2010. The randomized controlled clinical trials were selected based on specific criteria, in which a SFI plus platinum-based chemotherapy treatment group was compared with a platinum-based chemotherapy control group for patients with advanced NSCLC. The quality of studies was assessed by modified Jadad's scale, and Revman 4.2 software was used for data syntheses and analyses. RESULTS: Twenty nine studies were included in this review based on our selection criteria. Of them, ten studies were of high quality and the rest were of low quality, according to the modified Jadad scale. The meta-analysis showed there was a statistically significant higher tumor response (RR, 1.19; 95\% CI, 1.07 to 1.32; P = 0.001) and performance status ((RR, 1.57; 95\% CI, 1.45 to 1.70; P < 0.00001); but lower severe toxicity for WBC (RR, 0.37; 95\% CI, 0.29 to 0.47; P < 0.00001), PLT (RR, 0.33; 95\% CI, 0.21 to 0.52; P < 0.00001), HB (RR, 0.44; 95\% CI, 0.30 to 0.66; P < 0.0001) and nausea and vomiting (RR, 0.32; 95\% CI, 0.22 to 0.47; P < 0.00001), when the SFI plus platinum-based chemotherapy treatment group was compared with the platinum-based chemotherapy control group. Sensitivity analysis was restricted to studies with the high quality, and the result was similar when the studies with low quality were excluded. Asymmetry was observed in a funnel plot analysis, and Egger's test also indicated an evidence of publication bias (P = 0.016). CONCLUSIONS: SFI intervention appears to be useful to increase efficacy and reduce toxicity when combined with platinum-based chemotherapy for advanced NSCLC, although this result needs to be further verified by more high-quality trials.
