title: [Analysis of patients with gastrointestinal neuroendocrine tumor].
abstract: OBJECTIVE
  We investigated the background factors, histopathological results, and prognosis of patients with gastrointestinal neuroendocrine tumors.
  
  
  METHODS
  The medical records of 42 patients with gastrointestinal neuroendocrine tumors who were diagnosed and treated at our hospital from 2002 to 2012 were collected and retrospectively reviewed.
  
  
  RESULTS
  The ratio of male to female patients was 29:13; the mean age was 66.1 years. The tumors were located in the esophagus( 2 patients), stomach( 13 patients), duodenum( 9 patients), colon( 1 patient), and rectum( 18 patients). Regarding the depth of the tumor, invasion of the submucosa( SM) was observed in 26 patients; invasion of the muscularis propria( MP), in 1 patient; invasion of the subserosa( SS), in 3 patients; penetration of the serosa( SE)( AD), in 1 patient, invasion of the adjacent structures( SI)( AI), in 3 patients; and the extent of tumor invasion was unknown in 1 patient. Patients who experienced relapse had a poor prognosis, and all the patients died.
