目的 :分析直肠神经内分泌肿瘤的临床病理特征。方法 :选取本院2016年1月至2017年1月接诊的直肠神经内分泌肿瘤患者26例,对其临床资料进行回顾性分析,分析不同病理等级患者的性别、年龄、肿瘤直径、浸润深度、肝转移以及淋巴结转移方面上的差异。结果 :直肠神经内分泌肿瘤以男性为多见,肿瘤的易发部位为直肠中下段。其中35例Ki-67阳性指数低于2%,6例Ki-67阳性指数为3%~20%,4例指数超过20%。肿瘤的病理分级程度与年龄、肿瘤直径、浸润深度、淋巴结以及肝转移有明确关系。结论 :直肠神经内分泌肿瘤缺乏明显的特异性,可联合实验室检查Cg A、Syn和CD56染色结果来提高肿瘤的确诊率。
Objective: To analyze the clinicopathological features of rectal neuroendocrine tumors. Methods: Twenty-six patients with rectal neuroendocrine tumors admitted to our hospital from January 2016 to January 2017 were retrospectively analyzed. The data of gender, age, tumor diameter, depth of invasion, Liver metastasis and lymph node metastasis differences. Results: Rectal neuroendocrine tumors are more common in men, the tumor prone site for the lower rectum. 35 cases of Ki-67 positive index of less than 2%, 6 cases of Ki-67 positive index of 3% to 20%, 4 cases index of more than 20%. Tumor pathological grade and age, tumor diameter, depth of invasion, lymph nodes and liver metastases have a clear relationship. Conclusion: The neuroendocrine tumors of the rectum lacks obvious specificity. Combined with the laboratory examination of Cg A, Syn and CD56 staining results, the diagnosis rate of tumors can be increased.
