几种前列腺癌活检诊断方法的比较

依靠病理活检诊断前列腺癌一直是人们公认的有效和准确的方法，活检所得前列腺标本的来源主要有三个：（１）手术切除；（２）经尿道电切；（３）细针穿刺。本文作者对１３４５例前列腺活检标本进行回顾性分析，分别统计了上述三种不同病理活检方法对前列腺癌的检出率，结果发现，在三种活检标本中，癌检出率分别为：摘除标本３．５％（２２／６３５），电切标本２．６％（８／３１０），穿刺标本３３．８％（１３５／４００）。由此可见，细针穿刺前列腺癌的检出率最高，也是目前诊断前列腺癌的主要可靠方法。

Comparison of Diagnostic Biopsy Methods in Prostatic Carcinomas

The biopsy is still a standard method used to diagnose prostatic carcinomas up to now.The biopsy specimens of prostate are obtained mainly by three ways: prostatectomy, transurethral electric excision and fine needle aspiration. A series of 1345 cases of prostraic biopsy specimens were analysed retrospectively.The results showed that the detected prostatic carcinomas were 3.5%(22/635) from prostatectomy,2.6 (8/310)from transruethral electric excision and 33.8 (135/400) from fine needle aspiration. In conclusion, of three biopsy methods for prostatic carcinomas, fine needle aspiration was the highest efficient one.
