Objective  To summary the pathogenic site, clinical manifestations, endoscopic and radiographic features, pathologic characteristics, diagnosis, treatment, and prognosis of gastroenteropancreatic neuroendocrine neoplasm(GEP-NEN). Methods  Clinical data of 70 cases of GEP-NEN who were treated in Nanjing Drum Tower Hospital from Jan. 2003 to Dec. 2012 were collected and retrospectively analyzed. Results  Of the 70 cases, 35 cases(50.0%) were in pancreas, 18 cases(25.7%) were in rectum, 10 cases(14.3%) were in stomach, and 7 cases(10.0%) were in appendix; 55 cases(78.6%) were nonfunctional tumors, while 15 cases(21.4%) were functional; 50 cases(71.4%) were neuroendocrine tumor, 15 cases(21.4%) were neuroendocrine carcinoma, and 5 cases(7.2%) were mixed adenoendocrine carcinoma; 43 cases(61.4%) were in grade 1, 7 cases(10.0%) were in grade 2, and 20 cases(28.6%) were in grade 3 respectively. The detection rate of endoscopy, type-B ultrasonic, CT, and MRI were 90.0%(27/30), 67.9% (19/28), 86.0%(43/50), and 70.0%(7/10) respectively. A total of 67 patients(95.7%) were underwent surgery, including endoscopic resection, and 3 cases (4.3%) didn't receive surgery. Forty cases were followed-up for 6 months to 9 years(the median survival time was 3 years), and the 1-, 3-, and 5-year survival rates were 82.5%(33/40), 47.5%(19/40), and 35.0%(14/40) respectively. Conclusion  GEP-NEN occurs mainly in pancreas, and the clinical manifestations are variable. Endoscopy and radiographic examination methods play an important role in diagnosis of GEP-NEN, but final diagnosis is mainly based on pathological detection. Surgery is the main treatment method for it.
