Preliminary study on antitumor effect of active specific immunotherapy with autologous tumor vaccine in post-operative patients with advanced tumors / 中国免疫学杂志

ABSTRACT

Objective:The explore the mechanism of active immunotherapy with autologous tumor vaccine and clinical significance.Methods:30 patients with advanced tumors were enrolled in this study.4 weeks after operation,the patients received vaccinations of autologous tumor vaccine every 7～10 days for 4 times as adjuvant active immunotherapy,3 days before and 7 days after administrationsperipheral blood monuclear cells(PBMC) were isolated to assay the alteration of proportions of CD + 8 IFN ? + and CD + 8 IL 10 +,CD + 4 IFN ? + and CD + 4 IL 10 + cells.Meanwhile,serum IFN ? and IL 10 were measured within 48 hours after the skin tests with PPD and autologous tumor antigen,diameters of erythemas or indurations were observed.The clinical follow up was performed.Results:After active immunotherapy with autologous tumor vaccine.①The serum IFN ? was increased from (5.98?2 40)pg/ml to (11.20?4.76) pg/ml(P
