直肠类癌(附26例报告)

RECTAL CARCINOID TUMOR (REPORT OF 26 CASES)

为探讨直肠类癌的病理学特点、诊断及治疗选择，对我院１９８７～１９９７年１０年间收治的２６例直肠类癌病例进行回顾性总结。２６例术前均行直肠镜检查并经病理学检查而确诊，其中１９例分别做了局部切除或局部扩大切除，７例因肿块直径大于２ｃｍ而行根治性手术。术后随访１～１０年，死亡５例。作者认为，直肠镜检查是术前发现直肠类癌的重要手段，对可疑病变行活检时，除常规行ＨＥ染色外，应加做嗜银染色、亲银染色以及免疫组化检查。手术治疗是其最佳的治疗方法，手术切除的范围取决于原发肿瘤的大小、浸润程度。

To investigate the pathological characteristics, diagnosis and treatment of rectal carcinoid tumors, 26 cases, which had been diagnosed and treated in our hospital from 1987 to 1997, were retrospectively analysed. The rectoscopic examination were taken in all 26 patients and final diagnosis were made by pathological examination, among them, 19 cases were treated with local resection or expensively local resection, 7 cases with radical operation because the diameter of tumor was beyond 2 cm. These patiests were followed up 1-10 years with 5 patients died. The authors consider that rectoscopic examination and biopsy are important method to diagnose rectal carcinoid tumors preoperatively, in addition, for suspicious case, argentation and immunohistochemistry staining should be further made besides routine HE staining. The operative treatment is the best therapy to this kind of disease, the choice of operative mode must be made according to the size, infiltration of the tumor, the condition of infiltrated lymph node and hepatic metastasis.
