#3090 Retrospective Experience with Pherochromocytoma (PH) and Paraganglioma (PG) in a Single Argentinian Institution

Introduction: Pherochromocytoma (PH) and paraganglioma (PG) are neuroendocrine tumors arising in cromaffin cells in the adrenal medulla or extra adrenal paraganglia respectively. Clinical presentation is diverse. All PG/PH have malignant potential. Hereditary cases comprise up to 40% of all PG/PH.

#3080 Impact of Multimodal Perioperative Treatment in Patients with Resected Non-Metastatic Grade 3 Neuroendocrine Neoplasms (NEN G3)

Introduction: Patients with grade 3 neuroendocrine neoplasm (NEN G3) have a limited prognosis. Even in a non-metastatic stage, the risk of recurrence after surgery is high. Multimodal perioperative treatment, including chemotherapy and/or radiotherapy in an adjuvant or neoadjuvant setting, has improved the prognosis in numerous tumor entities; however, it has not been systematically evaluated in NEN G3 so far. Nevertheless, perioperative chemotherapy is generally recommended in most current treatment guidelines for NEN G3.

#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).

#3007 An mRNA-based Classifier Identifies PanNETs with Different Clinicopathological Characteristics

Introduction: Pancreatic neuroendocrine tumors (PanNETs) are a heterogeneous group of neoplasms that varies from indolent to highly aggressive diseases. Previous studies have suggested alterations of ATRX/DAXX as biomarkers of dismal prognosis, yet inconclusive data (especially in the metastatic setting) prevent those biomarkers to be used as routine clinical tests.
