#2798 Risk of Pre-Operative Understaging of Duodenal Neuroendocrine Tumors at Conventional Imaging: When Surgery Becomes the First Choice

Introduction: Duodenal neuroendocrine neoplasms (dNENs) are heterogeneous tumors that can exhibit aggressive behavior, with loco-regional nodes and distant metastases. Pre-treatment staging is the basis for planning either surgical or endoscopic treatment.

#2299 Expanding the WHO 2017 Classification to Gastrointestinal Tumors: Real-World Data from the R-GETNE Registry

Introduction: The update of the WHO 2017 classification of pancreatic neuroendocrine tumors (NETs) introduces the distinction between NET & NEC G3, based on histological differentiation. However, little is known about the possibility of extending this concept to non-pancreatic NETs.

#2256 Assessment of the Serum Levels of the Soluble Vascular Cellular Adhesion Molecule-1 (sVCAM-1) in Patients with Neuroendocrine Neoplasms

Introduction: Tumor growth and the ability to metastasize is a multistage process involving interactions between cancer cells and the vascular endothelium. These interactions have been reported to be mediated by various molecules including sVCAM-1. We have previously shown elevated serum concentration of sVCAM-1 in 82 neuroendocrine neoplasms (NEN) compared to controls. Here, we present results of the extension of the previous study.

#2187 Typical and Atypical Bronchial NETs with Advanced Disease: Incidence, Management and Survival

Introduction: Bronchial NETs are classified according to the 2004 WHO classification into typical, atypical and poorly differentiated. Typical and atypical tumours can develop metastatic disease (Stage IV) which requires careful management

#2145 Thrombotic Risk in Gastroenteropancreatic Neuroendocrine Tumors: A Single Centre Experience

Introduction: Neuroendocrine neoplasms (NENs) comprise a heterogeneous group of neoplasms associated with paraneoplastic syndromes. Venous thromboembolism (VTE) is a frequent complication in neoplastic patients and it is associated with increased morbidity and mortality. To date, there have been no specific studies in NEN, except for glucagon-secreting tumors
