Establishment of a detection platform for glioblastoma-dendritic cell (DC) vaccine preparation and to determine the efficacy of the vaccine in a clinical trial. Autologous glioblastoma-DC vaccine was prepared from a glioblast specimen procured from surgical resection. The specimen was used to enrich the vaccine with peripherally blood-derived DCs after heat-shock induced, glioblastoma apoptosis. The control group received conventional treatment of surgery and radio-chemotherapy post-operation. The therapeutic group received a combination of glioblastoma-DC vaccine and conventional therapy. A comparison of the functional immune parameters, including tumor control, rate live time, Karnofsky scores, and complications occurring in each group were observed and recorded. The proportions of peripheral CD3 +, CD3 +CD4 +, CD4 +/CD8 +, and NK cells were significantly higher after DC vaccination than the control group (P < 0.05). Serum levels of IL-2, IL-12, and IFN-γwere significantly higher after DC vaccination than in the control group (P < 0.05). Nine months after vaccination, tumor control rate is significantly improved in the DC group compared with the control group (P < 0.05); survival rate was significantly higher in DC group than in control group (P < 0.05) and the time to relapse was significantly longer in DC group than that in control group (P < 0.05). Karnofsky scores were better in DC vaccination group 6 and 9 months post-treatment compared with the control group (P < 0.05). The combination of glioma DC vaccine and radiotherapy/chemotherapy post-operatively enhances the immune function of patients, increases the tumor control rate, prolongs the survival time and relapse duration, improves the quality of life, and therefore provides a more effective intervention of treating glioblastoma. © 2011 Springer Science+Business Media, LLC.
