Core tip: An analysis of the clinicopathologic characteristics of a group of 57 patients with pathologically-confirmed diagnoses of rectal neuroendocrine tumors showed that these tumors mostly occur in the middle and lower rectum. The most common tumor-node-metastasis stage found was stage I, and lymph node or distant metastases were rarely seen. The major pathological type was a typical carcinoid tumor. Transanal extended excisions generally produced satisfactory curative effects, and the 5-year survival rate was as high as 88.6%. A multivariate analysis of the patient and tumor characteristics indicated that the pathological type is an independent prognostic factor.
