Between January 1989 and March 2002, we treated 299 male bladder cancer patients and 416 prostatic cancer patients. Of these, 17 patients (5.7% of the male bladder cancer patients and 4.1% of the prostatic cancer patients) had double cancer consisting of prostatic cancer and bladder cancer. The mean age at diagnosis of the first and second cancer was 71.6 years and 75.5 years, respectively. Of the 8 patients with synchronous tumors, 3 patients had latent prostate cancer when they underwent total cystoprostatectomy. The mean interval between the first and second cancer was 45.3 months. The mean follow-up period was 84.7 months (ranged from 5 to 324 months) and two patients died of cancer (bladder: 1, prostate: 1). In the literature, the coincidence of bladder cancer and prostatic cancer is the highest in the urological field. In follow up of either of these cancer patients, it is important to be aware of not only progression of the first cancer but also generation of a second cancer.
1989年1月至2002年3月期间，我们共治疗了299例男性膀胱癌患者和416例前列腺癌患者。其中，17例患者（占男性膀胱癌患者的5.7%，前列腺癌患者的4.1%）患有前列腺癌和膀胱癌组成的双重癌症。首次和第二次癌症诊断时的平均年龄分别为71.6岁和75.5岁。在8例同步肿瘤患者中，3例患者在接受全膀胱前列腺切除术时患有潜伏性前列腺癌。首次和第二次癌症之间的平均间隔为45.3个月。平均随访期为84.7个月（范围为5至324个月），2例患者死于癌症（膀胱癌：1例，前列腺癌：1例）。在文献中，膀胱癌和前列腺癌的并存情况在泌尿外科领域最为常见。在对这些癌症患者中的任何一种进行随访时，不仅要注意第一种癌症的进展，还要注意第二种癌症的发生，这一点很重要。
