摘要
目的 探讨经直肠超声引导下穿刺活检在前列腺上皮内肿瘤 (PIN)诊断中的临床价值。方法 回顾分析 3 17例疑前列腺疾病患者经穿刺活检证实的 3 8例PIN的临床资料。结果 2 6例PIN于前列腺周围区见低回声结节 ,其中PIN并前列腺癌和非癌PIN各占 3 4 .2 1% ( 13 / 3 8) ;另 12例PIN超声未见明确病灶 ,占3 1.5 8% ( 12 / 3 8)。PIN并前列腺癌的前列腺特异抗原 (PSA)和前列腺特异抗原密度 (PSAD)测值明显高于非癌PIN(P <0 .0 5、0 .0 0 1)。结论 经直肠超声引导下前列腺穿刺活检具有准确、安全等优点 ,是确诊PIN和前列腺癌的有效方法之一。
Objective To evaluate the clinical significance of biopsy guided by ultrasound in the diagnosis of prostatic intraepithelial neoplasia(PIN).Methods The clinical data of 38 PIN that they were from 317 suspicious prostatic cancer selected by biopsies were analyzed retrospectively. Results The low echogenic lesion was revealed in the peripheral zone of prostate in 26 PIN,in which the percentages of PIN with prostatic cancer and PIN were 34.21 %(13/38) each, respectively. The lesion was not revealed in 12 PIN, its percentage was 31.58%(12/38). The value of PSA,PSAD in PIN with prostatic cancer was significantly higher than that in PIN ( P < 0.05 , 001 ).Conclusions The biopsy of prostate guided by ultrasound is possessed of the advantages of accuracy and safety. It is one of effective methods in the diagnosis of PIN and prostatic cancer.
