[Augmentation of antitumor immunity in cancer chemotherapy].

Cancer chemotherapeutic drugs (antitumor drugs) generally inhibit host immune responses to cancer cells. Some antitumor drugs, however, can augment antitumor immune responses if they were administered appropriately. The immuno-augmentation brought about by antitumor drugs might concrete the effects of cancer chemotherapy. The authors introduced their experiments in which they have observed a typical BRM-like effects of bleomycin on tumor-bearing rats and discussed the significance of immuno-augmenting effects of antitumor drugs in cancer chemotherapy.
