Dye-Laser-Photoradiation-Therapy of Bladder Cancer after Photosensitization with Hematoporphyrin Derivative (HpD)-Basis for an Integral Irradiation
Bladder carcinoma is the second most common type of tumor within the urinary tract. Single bladder tumors can be treated and successfully destroyed by conventional methods such as transurethral electroresection of tumor or laser induced heat coagulation using,for example, a neodym-YAG laser beam. However, for at least 60% of all bladder carcinomas we are confronted with a multifocal growing tumor. In addition to the major tumor areas, which can be recognized easily macroscopically, the bladder very often contains widely distributed carcinoma in situ. It is not possible to treat these minute tumor foci sufficiently by means of conventional methods, including topical cytostatics treatment.
