Abstract
Radiation (XRT), hyperthermia, 2-deoxy-D-glucose (2DG), and Corynebacterium parvum were given in various combinations to BALB/c mice injected with herpes virus type 2-transformed (H238) cells. Addition of heat significantly increased the antitumor effects of XRT, and the combination of XRT + 2DG + heat resulted in the highest incidence of complete tumor regression. Enhanced activity of phytohemaggluti-nin-responsive T lymphocytes and natural killer cells capable of killing YAC-1 tumor cells was noted in some of the treatment groups while tumor volume was similar for all of the groups. This enhancement was most likely to be achieved when heat was included as part of the treatment protocol.
