title: Synchronous primary carcinomas of the bladder and prostate.
abstract: OBJECTIVE
  To determine the incidence of adenocarcinoma of the prostate for patients undergoing radical cystoprostatectomy for bladder cancer in Taiwan.
  
  
  METHODS
  A total of 248 patients in Taiwan who were histologically confirmed for transitional cell carcinoma of the bladder underwent cystoprostatectomy. Histopathologic evaluation of the prostate specimens sectioned at 5 mm intervals was performed.
  
  
  RESULTS
  Of the 248 patients, 10 (4.03%) were found to have prostate cancer. Of the 10 cases of unsuspected prostate cancer, eight proved to be at stage T1 or T2, and two at T3 and T4, respectively. This rate of incidentally found prostate cancer amongst our bladder cancer patients appeared to be lower than that found in bladder cancer patients in similar studies in USA.
  
  
  CONCLUSIONS
  Although the incidence of incidental prostate cancer in patients in Taiwan with bladder cancer is not high compared with that in Western countries, we suggest that digital rectal examination and prostate-specific antigen (PSA) are important screening tools for men with bladder cancer, especially for those aged 60 years and older in Taiwan.
