ABSTRACT:
Chemotherapy may be selectively localized to a tumor located at a point well within the human body by physically associating the chemotherapy agent with magnetic material having a Curie point temperature slightly above the normal temperature of the human body. Both materials may be associated with protein microspheres such as human serum albumin. By applying a magnetic field to the tumor location and then applying electromagnetic radiation to heat the Curie point magnetic material (so that it loses its magnetic properties), away from the tumor site, but not at the tumor site, the unheated magnetic material and the physically associated chemotherapy agent will be localized at the tumor. Radioactive material may also be employed to facilitate imaging of the concentration of the microspheres and for radiation treatment.
