Purpose: The aim of this study was to investigate the effect of a higher temperature on the efficacy of magnetic fluid hyperthermia for Lewis lung cancer in a mouse model. Materials and methods: Magnetic fluidswere prepared in vitro and directly injected into tumors. Twenty-four hours later, the micewere subjected to an alternating magnetic field. The temperature in the tumor was increased to 46.0 C, higher than the usual temperature used in hyperthermia therapy. The higher temperature was maintained for 30 min with a stable strength of magnetic field. Results: Magnetic fluid hyperthermia with a higher temperature significantly inhibited the growth of the tumors (P < 0.05). The tumors completely regressed in four out of 12 mice. Histological analysis demonstrated that the tumor cells underwent apoptosis and necrosis, and the cellswere arrested at the G(1)/G(0) phase of the cell cycle. The lifespan of the treated animals also increased significantly (P < 0.05). Conclusions: Magnetic fluid hyperthermia with a higher temperature could improve the efficacy of this therapy on lung cancer.
