This study was aimed to investigate the efficacy and safety of the combination treatment of dendritic cells co-cultured with cytokine-induced killer cells and chemotherapy for patients with advanced non-small-cell lung cancer (NSCLC). Literatures were searched from the Cochrane Library Central, PubMed, Web of Science and EMBASE. The primary endpoint of interest was overall survival (OS), and secondary endpoints were disease control rate (DCR) and progression free survival (PFS). Finally 7 trials published between January 2005 and March 2016 met inclusion criteria and totally 610 patients were enrolled. The combination group showed advance in DCR (RR = 1.31, 95% CI = 1.13-1.52, p = 0.0004), 1-year OS (RR = 1.18, 95% CI = 1.05-1.33, p = 0.007), and 2-year OS (RR = 1.37, 95% CI = 1.10-1.70, p = 0.005), with statistical significance. The proportions of CD3+ T cells (p = 0.002), NK cells (p = 0.02) and NKT cells (p = 0.001) were significantly higher in the peripheral blood of combination group, compared with those of the control group. Moreover, adverse reactions were obviously decreased in the combination group. However, no significant difference was identified in ORR and PFS between two groups (p > 0.05). In conclusion, the combination therapy was safe and applicable for patients with advanced NSCLC.
