#824 Metachronous Functioning Syndromes in Sporadic Pancreatic Neuroendocrine Tumors (PNET)
Introduction: A metachronous functioning syndrome (MFS) may develop during the evolution of PNET initially functioning or not.

#2200 Tumor Size Correlates with Grading in Nonfunctioning Pancreatic Neuroendocrine Tumors and Is Not Age-Dependent
Introduction: Tumor growth and Ki67 value increase are associated with aggressiveness in nonfunctioning pancreatic neuroendocrine tumours (NF-PanNET), but their natural history is largely unknown. It is unknown if the evolution of NF-PanNET is time-dependant.

#2963 Intrinsic Gene Programs in Metastasis-like Primary Subtype Is Associated with Early Metastatic Evolution in Pancreatic Neuroendocrine Tumours
Introduction: Three molecular subtypes of pancreatic neuroendocrine tumours (PanNETs) have been described: insulinoma-like, intermediate and metastasis-like primary (MLP). The Latter is a non-functional tumours with highly metastatic potential. A mouse model of PanNET showed that MLP subtype has two different pathways of progression including stem/progenitor and epithelial-to-mesenchymal transition. However, the evolution of metastasis in patients requires further studies.

#3056 Multi-Omic Characterization and Evolution of Neuroendocrine Neoplasm Organoids
Introduction: Molecular characterizations of neuroendocrine neoplasm (NENs) have unveiled candidate alterations associated with aggressiveness and suggested that the molecular link between neuroendocrine tumors (NETs) and neuroendocrine carcinomas (NECs) might be subtler than initially thought. For example, we have recently unveiled a new entity of pulmonary carcinoids (supra-carcinoids) with carcinoid-like morphology yet the molecular and clinical features of large cell neuroendocrine carcinoma (LCNEC). Testing hypotheses to explain aggressiveness and the possibility of progression or transition from NET to NEC through the accumulation of genetic anomalies requires in vitro and in vivo experimental models.

#664 Natural Course and Survival of Thymic and Bronchopulmonary Neuroendocrine Tumors are Different for Male and Female MEN-1 Patients
Introduction: The course of thymic- and bronchopulmonary neuroendocrine tumors (Th- and Bp-NET) in MEN-1 patients is still unclear.

#1523 Multiregion Analysis Reveal Evolutionary Patterns and a Chromosomal Instability Signature in Pancreatic Neuroendocrine Tumours
Introduction: Pancreatic neuroendocrine tumors (PNETs) are potentially lethal diseases that show variable degrees of proliferation and invasiveness. Although genetic subgroups have been suggested to give prognostic information the impact of clonal evolution to the development and outcome of PNETs remains unexplored.

#2809 Sporadic Neuroendocrine Neoplasms in Young Adult Patients: Natural History, Prognosis and Management
Introduction: Data specific to sporadic neuroendocrine neoplasms (NEN) in young adult patients (pts) are limited due to its rare occurrence.

#2855 Whole Exome Sequencing Reveals the Monoclonal Origin of Gastric Mixed Adenoneuroendocrine Carcinomas
Introduction: Gastric mixed adenoneuroendocrine carcinomas (g-MANECs) are rare neoplasms consisting of adenocarcinoma and neuroendocrine neoplastic components. G-MANECs show more malignant characteristics than gastric adenocarcinomas, while molecular mechanisms underlying the co-existence of the two components remains unknown.

#806 Long-Term Prognosis of Pancreatic Neuroendocrine Tumors in Von Hippel-Lindau Disease
Introduction: Management of pancreatic neuroendocrine tumours (PNET) associated with von Hippel-Lindau (VHL) disease is challenging because of their malignant potential and poorly predictable prognosis.

#2813 Clinical Presentation and Prognosis of Patients with Medullary Thyroid Cancer
Introduction: Medullary thyroid carcinoma (MTC) is a rare type of tumor that originates from parafollicular C-cells and accounts for 3–4% of all malignant thyroid neoplasms. MTC presents as sporadic (75–80%) or inherited tumors (20–25%). Hereditary MTC is part of multiple endocrine neoplasia type 2 (MEN2).
