Between January, 1994 and December, 1995, we performed systematic biopsy of the prostate in a secondary study of our mass screening program for prostatic diseases. Of the 3,219 males over 55 years of age, 25 patients with prostatic cancer (11 in stage B, 10 in stage C and 4 in stage D) were detected. Herein, the diagnostic accuracy of transrectal ultrasonography (TRS) was compared with that of prostate specific antigen (PSA) and digital rectal examination (DRE). The sensitivity of TRS, PSA and DRE for cancer were 80%, 84% and 64% respectively. The specificity, positive predictive value and accuracy of TRS for cancer were higher than those of PSA or DRE.
在1994年1月至1995年12月期间，我们在前列腺疾病大规模筛查项目的二次研究中对前列腺进行了系统活检。在3219名55岁以上的男性中，检测出25例前列腺癌患者（B期11例，C期10例，D期4例）。在此，比较了经直肠超声检查（TRS）与前列腺特异性抗原（PSA）和直肠指诊（DRE）的诊断准确性。TRS、PSA和DRE对癌症的敏感性分别为80%、84%和64%。TRS对癌症的特异性、阳性预测值和准确性高于PSA或DRE。
