[Targeting technology utilizing magnetic microparticulate system for cancer therapy].

Organ level-targeting of anticancer drugs or other relating stimuli to tumor tissues and their circumstances is important in cancer therapy. The successful targeting results in the greater antitumor effect and the lower numerous side effects. Application of a magnet from the outside of body is a useful tool to increase the targeting efficacy. In this review paper, targeting technology utilizing magnetic microparticulate system for cancer therapy was introduced and the future on the magnetic targeting system was augured.
