摘要
目的 评价经直肠超声引导下穿刺活检诊断前列腺癌 (PCA)的临床价值。方法 回顾性分析经直肠超声引导下穿刺活检诊断的 189例PCA临床资料和声像图表现。结果 111例声像图显示为单发癌肿 ,3 9例为弥漫性癌肿 ,还有 3 9例在声像图上未发现癌肿 ;在单发癌肿中有 63例瘤体最大径线≤ 1.5cm ,占 3 3 .3 3 %。前列腺特异抗原 (PSA)随癌肿最大径线增加而升高 (P <0 .0 5 ) ,且低分化组PSA明显高于高分化组 (P <0 .0 5 )。结论 经直肠超声引导下前列腺穿刺活检是一种安全的方法 。
Objective To evaluate the clinical value of transcrectal ultrasound guided biopsies in prostatic cancers(PCA). Methods The characteristics of clinical data and the sonography were analyzed retrospectively in the 189 PCA diagnosed by transcrectal ultrasound guided biopsies. Results There was single lesion in 111 patients, diffusive lesion in 39 patients. There was not any ultrasonographic finding in 39 patients. The size of single lesion in 63 patients was ≤ 1.5 cm,whose percentage was 33.33 %. The level of prostate specific antigen (PSA) was shown to increase with the size increasing of tumor (P< 0.05 ). PSA level in the low differentiation was higher than that of high differentiation significantly(P< 0.05 ).Conclusions Transcrectal ultrasound guided biopsy of the prostate is a safe method and beneficial to diagnose PCA of early stage.
