膀胱全摘除術後,早期に再発した膀胱癌症例の臨床病理学的検討

Abstract

In cases where of bladder cancer recurs within a year after total cystectomy, some failure or inadequacy in the operative management may be resposible. Recurrence of cancer within 8 months after the operation was found in eight of our 37 total cystectomy cases and they all died within 15 months. A retrospective study of the relationship of clinical and pathological diagnosis and autopsy findings and operative treatment performed led to the following conclusions; 1. Whenever evaluating the stage of the bladder cancer, an understaging (clinical stage< pathological stage) and overstaging (clinical stage <pathological stage) must be condemned. Especialy, an understaging of stage D is mostly followed by a poor outcome. 2. In the surgical treatment, the prevention of intrapelvic recurrence is very important. Radical cystectomy including pelvic lymphadenectomy is necessary even for clinically low stage bladder cancer, whenever cystectomy is required.
