Basic studies were performed to realize the combined therapy of the local radiation and the local hyperthermic treatments with less side-effects and high curative effect utilizing small seeds used for prostate cancer treatment also as heating mediators in magnetic hyperthermia. When applying the exchange magnetic field of 1 MHz and 50 Oe-rms, Ti needles, used as cold dummy of small seeds, functioned enough as heating mediators of magnetic hyperthermia through in-vivo tests. Moreover, it was found that the heat-shock protein(said to heighten the immunity effect) concentration in blood became high intentionally. This means that not only radiation and hyperthermia but also immune-therapies were expected when small seeds were used as heating mediators.
