Combined treatment of IL-2 and 60Co radiotherapy for malignant tumors and inductive ability of traditional Chinese medicine to IFN

With low dose IL-2 of stimulation with carboxy-methyl-Pachymaran (CMP) and 60Co irradiation, 37 patients with various malignant tumors were treated. Among these patients, there were 16 nasopharyngeal cancer, 4 esophageal cancer, 2 lung cancer, 6 non-Hodkin's lymphomas and 9 other cancer. The percentage of complete tumor remission was 51.4%; most partial remission was 46.8% and progression was 2.7%. Overall effectiveness rate was 97.3%, while 1 year survival rate was 86.2%, results indicated a possibility that combined therapy of IL-2 and 60Co irradiation may be effective in treatment of malignant tumors. Experimental study showed that RGP, RCP, PsP, PAS and CMP can promote inductive ability to IFN-α as well as to IFN-γ. (2 tabs., 1 fig.)
