目的：报告６５例经病理确诊的前列腺癌（ＰＣ），讨论其早期诊断的方法及其临床价值。方法：经直肠指诊（ＤＲＥ），经直肠赵声（ＴＲＵＳ），经腹会阴超声（ＴＰＡＵＳ），前列腺特异性抗原（ＰＳＡ）．酸性磷酸酶（ＰＡＰ）诊断前列腺癌。结果：以上几种诊断阳性率分别为８５％、７５％、６２％、＼８０％和３５％。手指引导经会阴、直肠及ＴＲＵＳ引导下三种穿刺活检的灵敏度分别为８２％、８４％和９２％。结论：ＤＲＥ，ＴＲＵＳ，ＰＳＡ及经直肠穿刺活检是目前筛选及早期诊断ＰＣ的重要方法。
OBJECTIVE: To report 65 cases of prostate cancer (PC) diagnosed by pathology, discuss its early diagnosis and its clinical value. Methods: Transrectal DRE, TRUS, TPAUS, prostate specific antigen (PSA). Acid phosphatase (PAP) diagnoses prostate cancer. RESULTS: The positive rates of these types of diagnosis were 85%, 75%, 62%, 80%, and 35%, respectively. The sensitivity of finger-guided transperineal, rectal, and TRUS-guided biopsy of the three types was 82%, 84%, and 92%, respectively. Conclusion: DRE, TRUS, PSA and transrectal biopsy are important methods for screening and early diagnosis of PC.
