目的:探讨直肠类癌临床病理特征。方法:分析12例直肠类癌患者临床病理资料及苏木精-伊红染色切片,进行免疫组化标记辅助诊断。结果:10例肿块直径<2cm,行直肠局部切除术;2例肿块直径>2cm,行根治术。12例铬粒素A(+),10例神经元特异性烯醇酶为(+),9例突触素(+)。1例可见淋巴结转移。结论:直肠类癌为低度恶性弥散性神经内分泌系统源性肿瘤,愈后较好。无转移者仅行手术治疗;有转移者术后可行化疗。
Objective: To investigate the clinicopathological features of rectal carcinoids. Methods: The clinical and pathological data of 12 patients with rectal carcinoid and the hematoxylin-eosin staining sections were analyzed, and the immunohistochemical markers were used to diagnose them. Results: The diameter of the tumor was less than 2 cm in 10 cases, and the resection of the rectum was performed. The diameter of the tumor was 2 cm in 2 cases and the radical operation was performed. 12 cases of chromegum A (+), 10 cases of neuron-specific enolase (+), 9 cases of synaptophysin (+). One case showed lymph node metastasis. Conclusion: Rectal carcinoids are low-grade malignant diffuse neuroendocrine system-derived tumors, and the prognosis is better. No transfer of only surgical treatment; metastasis feasible after chemotherapy.
