Abstract:
PURPOSE: The goal of this study was to review the clinicopathologic characteristics of neuroendocrine tumor (NET) of the stomach. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 13 patients who were diagnosed with neuroendocrine tumor from January 1999 to August 2007 at Kosin Medical Center; 4,159 gastric cancer patients were treated surgically during the same time. The average follow up period was 14.3 months. RESULTS: The majority of 13 patients were men (male-female ratio: 11:2) and the average age of patients with NET was 59.4 years (range: 42~72 years). The presenting symptoms were mostly epigastric pain and soreness. The tumor was limited to the mucosa or submucosa in two cases, and the tumor extended beyond the muscle layer in 11 cases. The mean size of the tumor was 7.0 cm, ranging from 0.7 cm to 15 cm. The type of the NEC (according to the WHO classification) was type 3 for eight patients, type 4 for four patients and type 1 for one patient. Regional lymph node metastasis was noted in 11 patients. Four cases showed recurrence of disease and the site of recurrence included liver in two patients, multiple organs (including the peritoneum and lung) in one patient and multiple organs (including liver, pancreas and duodenum) in one patient. The recurrent cases were type 3 and type 4 and the average survival period of the recurrent patients was 12.8 months. CONCLUSION: The majority of neuroendocrine tumors of the stomach were at an advanced stage at the time of diagnosis. These tumors frequently recurred in the liver and they have a poor prognosis.
