#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.

#2941 Mixed Urothelial and Neuroendocrine Carcinoma of the Urinary Bladder: Case Report and Literature Review

Introduction: Neuroendocrine tumors (NETs) comprise <1% of all bladder tumors,characterized by poor prognosis. These tumors may be either pure or impure, intermixed with urothelial carcinoma. There is currently no therapeutic consensus. We report the case of primary impure neuroendocrine carcinoma (NEC).

#2929 Type III Gastric Neuroendocrine Neoplasms: Is Local Excision Sufficient in Selected Cases?

Introduction: As per ENETS Guidelines, patients with type III gastric neuroendocrine neoplasms (t-III g-NEN), need to undergo partial or total gastrectomy. Data for less-extensive resections are limited.

#2852 Diagnostic Accuracy of Endoscopic Ultrasound-Fine Needle Aspiration (EUS-FNA) in the Evaluation of Pancreatic Neuroendocrine Neoplasms (PNEN) Grading

Introduction: Prognosis of pNENs depends on staging and grading, based on the cyto-histological Ki67 labelling; EUS-FNA is considered the gold standard technique to obtain it in pre-therapeutic setting
