#3045 Reliability and Agreement of Radiological and Pathological Tumor Size in Patients with MEN1-Related Pancreatic Neuroendocrine Tumors: Results from a Population-Based Cohort

Introduction: Pancreatic neuroendocrine tumors (pNETs) are the most lethal manifestation in patients with multiple endocrine neoplasia type 1 (MEN1). Tumor size is still regarded as the main prognostic factor and therefore used for surgical decision making.

#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.

#2881 Patient-Derived Tumor Xenograft Combined with Chemotherapy Drug Sensitivity Test in a Patient with Pancreatic Neuroendocrine Carcinoma

Introduction: Pancreatic neuroendocrine carcinoma (p-NEC) with liver metastasis has a poor prognosis. The treatment is mainly chemotherapy which is now still a huge challenge on NEC with high ki-67 index.
