本文报道了应用经直肠超声检查37例前列腺癌的结果。所有病例均行手术或穿刺活检，病理诊断均为腺癌。结果显示，经直肠超声对前列腺癌的诊断符合率为75．7％（28／37），阳性预期值为80．2％（41／50）。本文重点讨论了前列腺内低回声结节对前列腺癌早期诊断和随访的意义。超声检查对于发现有临床意义或潜在致命的前列腺癌具有较大意义。
This article reports the results of transrectal ultrasonography in 37 prostate cancer patients. All cases underwent surgical or biopsy, and the pathological diagnosis was adenocarcinoma. The results showed that the diagnostic accuracy of transrectal ultrasound in prostate cancer was 75.7% (28/37) and the positive predictive value was 80.2% (41/50). This article focuses on the significance of hypoechoic nodules in the prostate for the early diagnosis and follow-up of prostate cancer. Ultrasonography is of great significance for the detection of clinically significant or potentially fat prostate cancer.
