　前立腺特異抗原（PSA）が3ng/mlを超える，または臨床的に前立腺癌が疑われる152例に系統的前立腺生検を行った。生検は通常の6か所生検のほかに，辺縁域8か所と移行域2か所を加えた計16か所から経直腸的に施行した。癌は68例（45％）で認められたが，6か所生検のみでは15例（22％）で見逃されていた。6か所生検での見逃し症例数は，PSA 10ng/ml以下の群ではそれを超える群より，また，PSA density 0.2以下の群ではそれを超える群よりも有意に多く（p＝0.04およびp＜0.01），16か所生検は特にPSA 10ng/ml以下やPSA density 0.2以下の症例で有用と思われた。
