初回前立腺生検にて悪性所見を認めなかった患者の前立腺特異抗原の経時的変化について

Abstract

1)前立腺生検で良性疾患と診断された19名に対し経時的に前立腺特異抗原を測定した.5例に再生検を施行し, 3例の前立腺癌患者を発見した. 2)前立腺特異抗原の経時的変化をみることは再生検の必要性の判断の補助となる

To determine the need for repeat prostatic biopsy, we retrospectively evaluated 19 men for longitudinal prostate specific antigen (PSA) for more than 20 weeks from initial biopsy. Their initial biopsy results revealed no evidence of prostatic cancer. They had no surgical therapy or hormone therapy after it. If they had a 50% increase in the PSA level from initial biopsy, we performed the second biopsy. Of the 5 men who had the second biopsy, 3 men had prostatic cancer.
