目的 探讨前列腺偶发癌与前列腺增生 (BPH)及前列腺腺癌的关系及鉴别诊断。方法 术后标本中 ,发现前列腺偶发癌 (IDPC) 32例。其中用开放手术标本诊断率为 2 % (8/ 4 0 9) ,用经尿道电切方法诊断率为 7.2 % (2 4 / 311) ,病理诊断均为腺癌。结果 手术方法与IDPC的诊断密切相关 ,IDPC的发病率伴随BPH逐年同步增加。结论 IDPC与BPH同源 ,是BPH腺体的局部恶变 ,部分临床癌是IDPC恶化的结果。
Objective To investigate the relationship and differential diagnosis between incidental prostate cancer and benign prostatic hyperplasia (BPH) and prostatic adenocarcinoma. Methods In the postoperative specimens, 32 cases of idiopathic prostate cancer (IDPC) were found. Among them, the diagnostic rate of open surgical specimens was 2% (8/409), and the diagnostic rate of transurethral resection was 7.2% (24/31). The pathological diagnosis was adenocarcinoma. Results The method of operation was closely related to the diagnosis of IDPC. The incidence of IDPC increased with the increase of BPH year by year. Conclusion IDPC is homologous with BPH, which is a local malignancy of BPH gland. Some clinical cancers are the result of deterioration of IDPC.
