#1393

Introduction: Tumor grade is a major indicator of prognosis for neuroendocrine neoplasms.

Aim(s): To evaluate the clinical epidemiology features of gastric neuroendocrine neoplasms (GNEN) by grade.

Materials and methods: GNEN patients with the pathology results of mitotic count or Ki-67 index were selected in a national-wide study, which retrospectively surveyed 2010 GEP-NEN patients in seven Chinese regions. According to ENETS grading system, epidemiological and clinical features were compared between G1/G2 group and G3 group.
