前立腺癌検診を契機に発見された膀胱腫瘍についての検討

An investigation about the bladder tumor detected by the prostate cancer medical checkups

　2001年度および2002年度の前立腺特異抗原（以下PSA）を用いた前立腺癌検診にてPSA高値を指摘され，当科を受診し前立腺生検を施行した161名中6名に膀胱腫瘍の合併を認め，5名が膀胱癌，1名が膀胱内反乳頭腫であった。161名の前立腺生検の結果は55名が前立腺癌であったが，膀胱癌が発見された5名中4名は前立腺癌との同時性重複癌であり，前立腺癌患者における膀胱癌の合併率は7.27％と高率であった。前立腺癌と膀胱癌の重複率は高く，日常診療に際して注意が必要である。

After the introduction of PSA screening test started in the 2001 fiscal year in our county,161 patients consulted Mitoyo General Hospital for prostate cencer checkup in two years（2001 and 2002 fiscal year）. Among 161 patients,we found out fifty-five adenocarcinoma of the prostate and also five transitional cell carcinoma of the bladder and one inverted papilloma of the bladder. Four patients had the simultaneous double cancers（prostate and bladder）. In the prostate cancer,coincidence rate of the bladder cancer was 7.27％. The rate of coincidence of the prostate and bladder cancer is thus very high in our experience or in the literatures therefore,careful observation is required when examining the patients with prostate or bladder cancer patients.
