Advance of magnetic induction hyperthermia for malignant tumor

The magnetic induction hyperthermia for malignant tumor is a kind of new techniques where the heat is generated to kill the tumor lesion tissues through the magnetic media by the application of alternating magnetic fields. Since the development of the inductive heat treatment in the 1960s, many attempts were made to improve the effect of the heat treatment, to develop magnetic mediums with multimodality function and to optimize the temperature field distribution, for achieving numerous excellent results. This paper reviews the experimental studies and clinical applications of several magnetic materials, such as the ferromagnetic thermal seed, the magnetic liquid, the magnetic liposomes, the magnetic glass ceramic and the magnetic bone cement. In the meantime, the challenges in improving the efficiency of therapy and optimizing the heat field are also discussed.
