The clinical data on photodynamic treatment of bladder carcinoma in 117 patients confirmed that the treatment of bladder carcinoma of 1 cm to 2 cm in diameter may obtain better results. Carcinoma of 2-4 cm in diameter should be treated with increasing energy density and repeated exposure. If the carcinoma is larger than 4 cm in diameter or is involving the deep muscle and the cervix of the bladder, the treatment would be unsatisfactory. The tumor free rate in the 117 patients was 94%. The total recurrence rate was 30.1% after 8 years' follow-up. Finally, the indications for photodynamic treatment and the causes of recurrence were discussed.
117例膀胱癌光动力治疗的临床资料证实，直径1厘米至2厘米的膀胱癌治疗可能会取得较好效果。直径2至4厘米的癌肿应采用增加能量密度和重复照射的方法治疗。如果癌肿直径大于4厘米或累及膀胱深层肌肉和颈部，治疗效果将不理想。117例患者的肿瘤清除率为94%。8年随访后的总复发率为30.1%。最后，讨论了光动力治疗的适应证和复发原因。
