We reported 3 cases of rectal involvement by locally invasive prostate carcinoma which caused an urethrorectal fistula in case 1 and a rectal stenosis in case 2 and 3. Discriminating between primary rectal carcinoma and prostate carcinoma locally invasive to the rectum is very important because of distinct differences in treatment and prognosis. To confirm the tumor origin, tumor markers, proctosigmoidscopy, computerized tomography and biopsy with immunohistochemical staining for prostate specific antigen were useful.
我们报告了3例局部浸润性前列腺癌累及直肠的病例，其中病例1导致尿道直肠瘘，病例2和病例3导致直肠狭窄。区分原发性直肠癌和局部浸润直肠的前列腺癌非常重要，因为治疗方法和预后存在明显差异。为了确定肿瘤的起源，肿瘤标志物、直肠乙状结肠镜检查、计算机断层扫描以及前列腺特异性抗原免疫组化染色活检都很有用。
