浸润性膀胱癌的预后不佳,对不能手术切除的病例多数采用化疗、放疗或温热疗法。本文作者1978年来采用术前放射治疗,并比较分析了1975年1月～1984年12月,十年间应用术前放疗和术后放疗的疗效。全组资料中术前照射(Linac 40 Gy/4～5周)33例,术后照射(Linac50～60Gy/6～8周)19例。术前照射病例,通常于照射后1～2周施行膀胱全切除术。随访结 The prognosis of invasive bladder cancer is poor, and most cases that cannot be surgically treated are chemotherapy, radiotherapy or thermotherapy.

In preoperative radiation cases, cystectomy is usually performed 1 to 2 weeks after irradiation. Follow up
