Objective To explore the clinical features of gastric neuroendocrine neoplasms (GNENs). Methods A total of 36 patients with GNENs who were diagnosed between October 2005 and October 2015 at Peking Union Medical College Hospital were retrospectively analyzed. The demographic characteristics,clinical manifestations,endoscopic findings,and pathologic features as well as the treatments of GNENs were collected and analyzed. Results The average age of 36 patients was (55.8±11.1) years and the male to female ratio was 0.89:1. The clinical manifestations varied,in which abdominal pain was as high as 42.9%. Also,63.9% of the lesions were distributed in the gastric body. The endoscopic appearance of GNENs included polypoid lesions,ulcerative lesions,and mucosal depression. Polypoid lesions were most common,and 73.9% of these polyps were single,with an average diameter of less than 10 mm. Pathological grading included G1-G3 level,while G1 level accounted for 55.6%. Up to 65.2% of patients who undergone gastric body biopsy had pathologic evidence of mucosa atrophy or metaplasia. Therapeutic modalities included endoscopic intervention and surgical resection. Conclusion Patients with GNENs lack specific symptoms. The most common endoscopic appearance is polypoid lesions,mainly in gastric body. Clinicians should be aware of the possibility of GNENs in the polypoid lesions,particularly for those accompanied with gastric body atrophy.
