ABSTRACT

Objective:To investigate the effect of immunotherapy with dendritic cells and cytokine-induced killer cells combined with chemotherapy on apoptosis-related genes and immune function in patients with middle- and advanced-stage non-small cell lung cancer.Methods:A total of 100 patients with middle- and advanced-stage non-small cell lung cancer who received treatment in Taizhou Hospital of Zhejiang Province, Wenzhou Medical University, China from February 2018 to May 2019 were included in this study. They were randomly divided into control and observation groups ( n = 50/group). The two groups were given chemotherapy with pemetrexed and cisplatin. The observation group was given immunotherapy with dendritic cells and cytokine-induced killer cells based on chemotherapy with pemetrexed and cisplatin. Changes in apoptosis-related genes [primary autosomal recessive microcephaly gene (MCPH1), ataxia-telangiectasia mutated (ATM), ataxia telangiectasia mutated and Rad3 related (ATR), transcription factor 21 (TCF21)] and immune function were monitored. Clinical efficacy of immunotherapy with dendritic cells and cytokine-induced killer cells combined with chemotherapy with pemetrexed and cisplatin in the treatment middle-and advanced-stage non-small cell lung cancer was assessed. Results:After treatment, expression of MCPH1, ATM, ATR and TCF21 in the observation group was 301.11 ± 41.12, 239.98 ± 30.15, 270.01 ± 36.01, 270.01 ± 34.02, respectively, which was significantly higher than that in the control group [101.32 ± 15.32, 103.00 ± 13.97, 101.12 ± 14.90, 100.20 ± 14.99, t = 32.194, 29.149, 30.644, 32.299, all P < 0.001]. The proportion of the number of Th1-positive cells in the number of CD +4 T cells in the observation group was significantly higher than that in the control group [(29.00 ± 3.41)% vs. (22.61 ± 3.22)%, t = 9.634, P < 0.001]. The proportion of the number of Th17-,Th2 and CD +4CD +25Treg-positive cells in the number of CD +4 T cells in the observation group were (0.89 ± 0.10)%, (12.01 ± 1.36)%, (11.02 ± 1.92)%, respectively, which were significantly lower than those in the control group [(1.70 ± 0.20)%, (17.61 ± 2.20)%, (18.70 ± 2.40%)%, t = 25.614, 15.310, 17.670, all P < 0.001]. Total effective rate in the observation group was significantly higher than that in the control group [52.0% (26/50) vs. 30.0% (15/50), χ2 = 5.002, P < 0.05]. Conclusion:Immunotherapy with dendritic cells and cytokine-induced killer cells combined with chemotherapy with pemetrexed and cisplatin can induce apoptosis and regulate immune function. The combined therapy exhibits better clinical efficacy in the treatment of non-small cell lung than chemotherapy alone.
