A clinical study evaluating dendritic and cytokine-induced killer cells combined with concurrent radiochemotherapy for stage IIIB non-small cell lung cancer.

To compare the efficacy of dendritic and cytokine-induced killer cells (DC-CIK) therapy combined with concurrent radiochemotherapy on stage IIIB non-small cell lung cancer. Sixty-three patients with stage IIIB non-small cell lung cancer were randomly divided into the study and control groups. The study group, comprising 30 patients, was treated with DC-CIK combined with docetaxel-cisplatin chemotherapy and synchronization conformal radiotherapy. The control group including 33 patients was only treated with docetaxel-cisplatin chemotherapy and synchronization conformal radiotherapy. The efficacy, Karnofsky performance score (KPS), tumor markers, 6-month and 12-month survival rate, T cell subsets, and adverse reactions of the two groups were compared. The response rate of the study group was 83.3% (25/30), and that of the control group was only 54.5% (18/33). Furthermore, the KPS, T cell subsets, and 12-month survival rate was significantly higher in the study group, and there were significant differences between the two groups. The two groups had no significant difference in adverse reactions. The combined DC-CIK therapy, with synchronous radiotherapy and chemotherapy to treat stage IIIB non-small cell lung cancer was superior to single synchronous radiotherapy and chemotherapy. The combined therapy can improve the life quality and prolong the survival time of the patients.
