#3022 Diagnostic Accuracy of 68Gallium Positron Emission Tomography (68Ga PET), Endoscopic Ultrasound (EUS) and Computed Tomography in the Assessment of Lymphnode Metastases by Nonfunctioning Pancreatic Neuroendocrine Neoplasms

Introduction: The presence of nodal metastasis is one of the most important predictive factors for recurrence after radical surgery for nonfunctioning Pancreatic Neuroendocrine Neoplasms (NF-PanNEN). Nevertheless, it is not clear which is the best diagnostic examination to identify preoperatively lymphnodal metastasis.

#3014 The Number of Positive Nodes Accurately Predicts Recurrence after Distal Pancreatectomy for Nonfunctioning Neuroendocrine Neoplasms

Introduction: The most appropriate staging system of metastatic lymph nodes (N) for resected pancreatic neuroendocrine tumors (PanNETs) remains unclear, especially regarding those resected by distal pancreatectomy (DP).

#2992 The PanNENomics Project: A Call for an International Collaborative Effort Built on the Success of the LungNENomics Project

Introduction: Neuroendocrine tumors are rare understudied diseases at the molecular level, especially those occurring in sites outside the lung and the gastrointestinal track. This lack of knowledge has strong implications for the clinical management of these diseases (Rindi et al. Mad Pathol 2018).

#2951 Analysis of Discordance between Biopsy Grade and Surgical Pathology Grade in Resected PanNEN Patients

Introduction: In PanNEN cases, treatment strategies are decided by tumor localization, volume and grade. In unresectable or metastatic cases, tumor grade is determined by biopsy specimen obtained from EUS-FNA and diagnostic accuracy of biopsy according to WHO classification 2017 is important for decision making of treatment.
