title: Artificial cytokine storm combined with hyperthermia induces significant anti-tumor effect in mice inoculated with lewis lung carcinoma and B16 melanoma cells.
abstract: In cancer immunotherapies combined with hyperthermia, one or two cytokines have been tested to augment the anti-tumor effect. However, the therapies have not shown sufficient improvement. The aim of this study is to find a new potent tumor immunotherapy in order to augment antitumor effect of hyperthermia by the cytokine cocktails in vivo. We used a combination therapy of local hyperthermia (LH) and various cytokine cocktails composed of IFNs (IFN-alpha, -beta, and -gamma), Thl cytokines (IL-2, -12, -15, and -18), a Th2 cytokine (IL-4), inflammatory cytokines (IL-lalpha and TNF-alpha), and dendritic cell-inducible cytokines (IL-3 and GM-CSF). These cytokines in a proper combination augmented the anti-tumor effect of LH and prolonged survival time in Lewis lung carcinoma or B16 melanoma significantly. Moreover, the 12-cytokine cocktail suppressed B 16 metastasis to the lung and lymph nodes, and complete regression of the tumors without regrowth occurred in 3 of 5 mice. In the cured three B16 mice, there was hyperplasia of lymphatic organs with many CD3-positive T lymphocytes. The most effective cytokine combination should be able to augment the anti-tumor effect of other therapies besides hyperthermia that induce the necrosis of tumor cells.
