To treat Liver cancer with PDT, it is essential to accumulate much more photosensitizer in the to than in normal Liver tissue. We succeeded in accumulating a sensitizer selectively in liver tumor by intraarterial administration of pheophorbide a dissolved in Lipiodol. With this technique and activation by 670 nm Light of Nd-YAG dye laser, we produced severe PDT necrosis in Liver tumor of the rat without damage of surrounding Liver tissue.
