回顾分析６６例前列腺癌并复习文献，认为前列腺癌绝大多数发生于老年男性，常伴有前列腺增生症。８７．９％可通过肛指检查扪及，肛指可用于健康体检发现早期病例。经直肠Ｂ超可发现部分肛指未能扪及病例。细针穿刺活检仍是目前确诊前列腺癌最重要的方法，简便、阳性率高、无严重并发症。血清瘤标以ＰＳＡ最重要，有较高的敏感性及特异性，结合肛指、经直肠Ｂ超等可诊断前列腺癌，对前列腺增大的老年人应列为常规检查项目。ＣＴ对局部浸润及淋巴结转移有较大价值，核素扫描能发现较早期骨转移灶。
Retrospective analysis of 66 cases of prostate cancer and review the literature that the vast majority of prostate cancer occurs in older men, often accompanied by benign prostatic hyperplasia. 87.9% palpable by the anal finger, anal finger can be used to detect early cases of physical examination. Transrectal B-ultrasound can be found in part of the anal finger failed to palpable cases. Fine-needle aspiration biopsy is still the most important method for the diagnosis of prostate cancer. It is simple and has a high positive rate without serious complications. Serum tumor markers to PSA the most important, high sensitivity and specificity, combined with the anal finger, transrectal ultrasound B can be diagnosed with prostate cancer, prostate enlargement of the elderly should be classified as routine inspection items. CT is more valuable for local infiltration and lymph node metastasis, radionuclide scanning can detect earlier bone metastases.
