摘要
目的 探讨经直肠超声 (TRUS)引导下重复穿刺诊断前列腺癌 (PCA)的临床价值。方法5 4例患者TRUS引导下首次穿刺活检诊断为前列腺良性病变 ,后因患者为PCA高危人群进行了TRUS引导下重复穿刺活检。前列腺特异性抗原范围 0 .5～ 90 .0 μg/L ,平均 16.3 μg/L。 2 9例直肠指检异常 ,2 1例TRUS异常。结果 在 5 4例前列腺重复穿刺的患者中 ,47例穿刺 2次 ,6例穿刺 3次 ,1例穿刺 4次 ;确诊PCA 14例 ( 2 5 .9% ) ,良性前列腺增生 3 1例 ,前列腺上皮内肿瘤 5例 ,慢性前列腺炎症 4例。结论对于既往穿刺诊断为良性病变的PCA高危人群开展重复穿刺可以提高PCA的诊断率。
Objective To evaluate the clinical value of repeat transrectal ultrasound (TRUS) guided biopsy in prostatic cancer (PCA). Methods Repeat TRUS guided biopsy was conducted on 54 patients of the previous benign TRUS guided biopsy at high risk of PCA. Postatic specific antigen ranged in 0.5- 90.0 μg/L(mean 16.3 μg/L). Twenty-nine patients were abnormal in digital rectal examination, 21 patients were abnormal in TRUS. Results Forty-seven patients had 2 consecutive times of the biopsy, 6 patients had 3 consecutive times, 1 patient had 4 consecutive times in 54 patients of repeat TRUS guided biopsy. The pathological finding was confirmed in 14 PCA ( 25.9%), and 31 benign prostatic hyperplasia, 5 prostatic intra-epithelial neoplasmia, 4 chronic prostatitis. Conclusions The detection of PCA will be increased by repeat TRUS guided biopsy at high risk of PCA after the previous benign TRUS guided biopsy.
