Abstract

Background: Kanglaite injection (KLT) is a broad-spectrum anti-tumor drug, which is extracted from the seeds of the Chinese medicinal herb Coix lacryma-jobi, and has been widely used for the treatment of advanced lung cancer.

Purpose: To evaluate the combined effects of Kanglaite injection plus platinum-based chemotherapy (PBC) on patients with stage III/IV non-small cell lung cancer (NSCLC).

Study design: A systematic review and meta-analysis of randomized clinical trials (RCTs).

Materials and methods: Twelve databases were searched from their inceptions until July 05, 2019. All the RCTs comparing the efficacy and safety of Kanglaite injection plus PBC versus PBC alone were selected. Analyses were performed using Review Manager 5.3, Comprehensive Meta-Analysis 3.0 and Trial Sequential Analysis (TSA). Disease control rate (DCR) was defined as the primary endpoint, objective response rate (ORR), survival rate, quality of life (QOL), cellular immunity function, and toxicities were defined as the secondary endpoints.

Results: Twenty-seven RCTs recruiting 2,243 patients with stage III/IV NSCLC were included. The results showed that, compared with PBC alone, Kanglaite injection plus PBC improved DCR (RR = 1.20, 95% CI 1.15-1.26, p < 0.00001), ORR (RR = 1.45, 95% CI 1.31-1.60, p < 0.00001), 1-year survival rate (RR = 1.20, 95% CI 1.02-1.43, p = 0.03), QOL (RR = 1.32, 95% CI 1.25-1.40, p < 0.00001), CD4+T cells (WMD = 4.86, 95% CI 4.00-5.73, p < 0.00001), CD4+/CD8+ ratio (WMD = 0.19, 95% CI 0.07-0.31, p < 0.002), and reduced severe toxicities by 59% (RR = 0.41, 95% CI 0.33-0.51, p < 0.00001). Most results were robust and the quality of evidence was from moderate to low.

Conclusions: Kanglaite injection in combination with PBC showed significantly higher efficacy than PBC alone in the treatment of stage III/IV NSCLC. Moreover, the combination therapy can improve cellular immunity and attenuate the severe toxicities caused by chemotherapy. However, high-quality RCTs are warranted to further assess the effects of the combined therapy.
