Transrectal ultrasound and TRUS-guided needle biopsy was studied in office practice to detect prostate cancer in men with palpably irregular prostates or elevated tumor markers (PAP/PSA). Of 330 men examined, 118 had TRUS biopsy: 33 were positive for adenocarcinoma, 13 were small volume, low stage lesions treated by R.R.P. Twenty-eight percent of all patients biopsied had adenocarcinoma: 11% (13) had low volume, low stage disease potentially curable by radical surgery, representing 4% of the total studied. TRUS in combination with markers does aid in the diagnosis of low stage prostatic adenocarcinoma. It is a practical, useful, office-based urologic procedure.
在门诊实践中对经直肠超声及经直肠超声引导下穿刺活检进行了研究，以检测前列腺触诊不规则或肿瘤标志物（前列腺酸性磷酸酶/前列腺特异抗原）升高的男性中的前列腺癌。在接受检查的330名男性中，118人接受了经直肠超声引导下穿刺活检：33人腺癌检测呈阳性，13人为小体积、低分期病变，接受了根治性前列腺切除术。所有接受活检的患者中有28%患有腺癌：11%（13人）患有小体积、低分期疾病，有可能通过根治性手术治愈，占总研究人数的4%。经直肠超声结合标志物确实有助于诊断低分期前列腺腺癌。这是一种实用、有效的门诊泌尿外科检查方法。
