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。
The authors reported 19 cases of rectal carcinoid tumors, including 11 cases of benign carcinoid and 8 cases of malignant. The clinical manifestations of carcinoid syndrome were found in 3 cases, and liver metastases were found in 5 cases during the operation. As it is currently not possible to judge the benign and malignant carcinoid tumors histologically. Therefore, the size of carcinoid tumors still has important reference value in judging benign and malignant diseases, but the main basis is whether there is local infiltration and distant metastasis. Immunohistochemical examination of carcinoid tract carcinoids suggests that the occurrence or absence of carcinoid syndrome is mainly determined by the type and amount of active substances secreted by the cancer cells. In patients with rectal carcinoid <2cm in diameter and no local infiltration, local resection may be performed. Diameter ≥ 2cm, while there is local infiltration, radical surgery should be performed.
