Abstract BACKGROUND: We performed prostate-specific antigen (PSA) screening and evaluated its usefulness in outpatients with bladder cancer who may have an elevated risk for prostate cancer. METHODS: Sixty-one new or followed-up outpatients with bladder cancer were examined between September 1999 and December 2000 in the Department of Urology, Gunma University Hospital, Japan. PSA was measured after informed consent was obtained, and patients in whom the PSA level was 4.1 ng/mL or higher were selected for thorough examination. In the examination, one examiner performed DRE (digital rectal examination) and, based on DRE and TRUS (transrectal ultrasonography) findings, determined whether prostate biopsy was indicated. RESULTS: The average age of the 61 cases was 69.1 +/- 8.6 years, and the average PSA level was 3.5 +/- 5.8 ng/mL. The PSA level was 4.1 ng/mL or higher in 11 (18.0\%) patients, nine of whom underwent six-sextant biopsy under TRUS guidance. Of these nine cases, four (6.6\%) were diagnosed as having prostate cancer. The Gleason score was 7 in three cases and 9 in one case. The clinical stage was T2N0M0 in three cases and T3N0M0 in one case. CONCLUSIONS: On PSA screening in patients with bladder cancer and patients with a history of transurethral resection of the bladder tumor (TUR-BT), prostate cancer was found in 6.6\%. This rate is higher than in the general population. These cancers were classified into intermediate to high-risk groups, and the prognosis of prostate cancers could be more important than those of the bladder cancers in two cases (50\%). We conclude that PSA screening for inpatients with bladder cancer may be useful.
