Beam irradiation to multiple treatment site within a tumor for the enhancement effect of phototherapy

摘要

(57) beam is irradiated for a long time (52) a plurality of locations distributed to the abnormal tissue tumors (22) [summary] In photodynamic therapy (PDT). The volume of abnormal tissue within a tumor that has been destroyed by phototherapy long time using (50a-50e) a plurality of probes can be those substantially greater than that expected based on the prior art, according to clinical trials were. I use by separating the probe or emitted light the plurality of fibers in this process. By damage to the blood vessels that supply system tumors (blood rich in oxygen to the tumor part of the expected fluence outside the region and immune response of the patient''s body that occurs as a result as well as the concomitant effect of one or more, including inflammation of the abnormal tissue that has been damaged be larger (38) necrosis volume of 22).
