Objective:To evaluate the clinical efficacy of dendritic cells-cytokine induced killer(DC-CIK) cells combined with surgi-cal treatment for hepatocellular carcinoma(HCC). Methods:Totally 67 patients with HCC were randomly divided into treatment group (n=34) and control group(n=33). The patients in control group were received hepatectomy while those in treatment group were given hepatectomy combined with DC-CIK cell treatment. The immune function,quality of life,tumor recurrence rate and adverse reactions were analyzed postoperatively. Results:In treatment group,the proportion of CD3+,CD4+,CD16+CD56+ and the ratio of CD4+ against CD8+ were increased and the proportion of CD8+ effect cells was decreased significantly after DC-CIK cell treatment compared with those before DC-CIK cell treatment,with statistical differences(P<0.05). After treatment,the proportion of CD3+,CD4+,CD16+CD56+ and the ratio of CD4+ against CD8+ were increased and the proportion of CD8+ effect cells was decreased significantly in treatment group compared with those in control group,with statistical differences(P<0.05). Quality of life of 61.8% patients in treatment group was improved,significantly higher than that of 36.4% in control group(P<0.05). The 1-year survival rate and 1-year recurrence rate in treatment group and control group were 91.2% vs. 81.8% and 8.8% vs. 15.2% respectively,with no significant statistical difference between two groups(P >0.05). The side effects of DC-CIK cells treatment were fever,chills and could be alleviated after symptomatic treatment. Conclusions:DC-CIK cells combined with surgical treatment for patients with hepatocellular carcinoma is safe and effec-tive and it plays an important role in improving immune function and quality of life of HCC patients.
