#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.

#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.

#2939 Prognostic Evaluation for Gastroenteropancreatic NEC: AJCC or ENETS Staging Classification or Others?

Introduction: For poorly-differentiated gastroenteropancreatic neuroendocrine carcinoma (GEP-NEC), American Joint Committee on Cancer (AJCC) recommends to use a classification different from that for well-differentiated neuroendocrine tumor. However, this is not adopted by European Neuroendocrine Tumor Society (ENETS) staging classification.
