Abstract

We report 117 cases of clinical data of photodynamic treatment of bladder cancer and confirm that treatment of the bladder cancer between 1 cm to 2 cm in diameter should get better results. That of 2 - 4 cm diameter needs increased energy density and repeated exposures. If the cancer is larger than 4 cm diameter or includes invasion of the deep muscle and the cervix of the bladder, the results of treatment would not be satisfactory. The elimination rate of cancers in this group of patients was 94%. The total recurrence rate reduced to 30.1% after the survey of patients in 8 years. By the way, we also discuss and investigate the results, the mechanism, and the cause which decreased the rate of recurrence in photodynamic treatment of bladder cancer.
