Clinicopathological Features of the High Grade Pancreatic Neuroendocrine Neoplasms Abstract #2133

Introduction: The high grade pancreatic neuroendocrine neoplasms (PanNENs) include well-differentiated tumors (WD-NETs) with elevated proliferation and poorly differentiated carcinomas (PD-NECs).
Aim(s): The aim of the study was to assess clinicopathological features and survival outcomes of PanNEN that are G3 by Ki67 index.
Materials and methods: The study included 130 resected PanNENs, which were reviewed for morphology and immunohistochemistry and graded according to the WHO 2017 criterions. 20 cases were selected as study high grade (G3) group. The results were correlated with clinicopathologic data, overall (OS) and disease-free survival (DFS).

#2717 64Cu-DOTATATE PET/CT Predicts Progression-Free Survival in Patients with Neuroendocrine Neoplasms
Introduction: The degree of overexpression of somatostatin receptors in patients with neuroendocrine neoplasms (NEN) may reflect tumor differentiation and thus be associated with prognosis. Non-invasive quantification of receptor density is possible by somatostatin receptor imaging (SRI) using positron emission tomography (PET).

Introduction: Surgery is the principal treatment for loco-regional gastroenteropancreatic (GEP) neuroendocrine tumors (NET). However, whether surgery is beneficial in high-grade neuroendocrine neoplasms (NEN) and mixed neuroendocrine-non neuroendocrine neoplasms (MiNEN) is not known.
