Heterogeneity of Type 1 Gastric Neuroendocrine Neoplasms

#1822

Introduction: Type 1 gastric Neuroendocrine Neoplasms (gNENs) are defined when atrophic body gastritis is associated. They are mostly multiple, small, with a low grade histology with low metastatic risk. Data on factors associated with malignant tumor behavior in these patients are scarce.

Aim(s): Identify subgroups of patients with potential risk of malignant behavior among type 1 gNENs.

Materials and methods: Multi-center retrospective study including type 1 gNENs. Tumors were divided according ENETS staging and grading system. Pearson coefficient was used to assess correlation.
