Methods The medical charts of 300 male patients who underwent radical cystoprostatectomy for bladder cancer between 1997 and 2005 were retrospectively reviewed. The mean age of the patients was 62 range 51-75 years. Results Prostate adenocarcinoma was present in 60 20 of 300 specimens. All were acinar adenocarcinoma. Of these 40 were located in peripheral zone 20 had pT2a tumor 12 20 had pT2b tumor 22 had pT2c and 6 10 had pT3a tumor. Gleason score was 6 or less in 48 80 patients. Surgical margins were negative in 54 90 patients and tumor volume was less than cc in 23 patients. Of the 60 incidentally detected cases of prostate adenocarcinoma 40 were considered clinically significant. Conclusion Incidentally detected prostate adenocarcinoma is frequently observed in radical cystoprostatectomy specimens. The majority are clinically significant.
