直肠类癌19例分析

Rectal carcinoid:analysis of 19 cases

作者报道19例直肠类癌,其中良性类癌11例,恶性8例。3例有类癌综合症的临床表现,5例于术中发现有肝转移。由于目前尚无法从组织学上判断类癌的良恶性。故类癌瘤的大小在判断良恶性方面仍有重要参考价值;但主要依据为是否有局部浸润和远处转移。消化道类癌的免疫组化检查提示,类癌综合症的发生与否主要按类癌细胞分泌活性物质的种类和其数量的多寡而定。直径<2cm 的直肠类癌,又无局部浸润时,可行局部切除术。直径≥2cm,同时又有局部浸润时,应行根治术。

This article reported 19 patients with carcinoid tu- mor of the rectum.Among them,there were benign in 11 and malignant in 8.Three patients had carcinoid syn- drome and five patients had metastasis in the liver.There were no means to judge the benign or malignant from the pathology,therefor it is important to determine the gross size of carcinoid tumor.But local invasion and re- mote metastasis was main basis of diagnosis.Carcinoid syndrome depends upon the quantity of the hormonal se- cretion from carcinoid cells.Most tumor large than 2cm in diameter should be subject to local excision,however targer than 2 cm in diameter and with local invasion or metastasis should be treated with radical resection.
