Background: Because the incidence of gastric neuroendocrine tumors (NETs) has recently increased due to advanced diagnostic methods and awareness of gastric NETs, we investigated clinicopathological characteristics and treatment results in patients with gastric NETs. Methods: We retrospectively reviewed the medical records of 27 patients (17 males, mean age: 56 years) with gastric NETs who were diagnosed and treated at Chonnam national university hospital from January 2004 to July 2014. Results: The study included 27 patients with gastric NETs who had a total of 54 lesions. The tumors were located in the body (48/52 lesions, 92.3%), fundus (3/52 lesions, 5.7%), and antrum (1/52 lesions, 2.0%). Most of the tumors were solitary (24/27 patients, 88.8%). The median size was 6.6mm (range 2-20). Most of the tumors (94.2%) were classifi ed into WHO grade 1. Methods of treatment were endoscopic mucosal resection, endoscopic submucosal dissection, cold and hot biopsy, argon plasma coagulation, wedge resection (56.5%, 10.9%, 21.7%, 2.2%, 8.7% respectively). No procedure- related complications occurred. Median follow-up time was 14 months (range 2-78). Recurrence rate was 25%. Gastric adenoma including low and high gradedysplasia was identifi ed in 25.9% (7/27 patients) during initial diagnosis and follow-up period. Conclusions: Endoscopic resection of gastric NETs is a safe and effective treatment option with a relatively low recurrence rate. The close observation about coincidence of gastric adenoma should be considered during endoscopy surveillance in patient with gastric NETs.
