#3062 The Splicing Factor CELF4 Is Dysregulated in Neuroendocrine Tumors, Where It Can Enhance Aggressiveness Features
Introduction: There is increasing evidence that alterations in alternative splicing are linked to key tumor features in different cancers. Besides mutations, dysregulation of the splicing machinery would represent the main underlying cause for these alterations. Indeed, splicing dysregulation is emerging as a novel, transversal cancer hallmark, due to its association with multiple dysfunctions in tumor cells.

#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.

#2742 Anti-Tumor Effects of Semaphorin 4D Blockade Unravel a Novel Pro-Invasive Mechanism of Vascular Targeting Agents
Introduction: One of the main consequences of inhibition of neovessel growth produced by angiogenesis inhibitors is increased intratumor hypoxia. Growing evidence indicates that tumor cells escape from this hypoxic environment to better nourished locations, presenting hypoxia as a positive stimulus for invasion. Particularly, anti-VEGF/R therapies produce hypoxia-induced invasion and metastasis in a spontaneous mouse model of pancreatic neuroendocrine cancer, RIP1-Tag2.

#2934 Vasostatin-1 Predicts Recurrence in Patients Submitted to Surgery for Nonfunctioning Pancreatic Neuroendocrine Tumors (NF-PanNET)
Introduction: An association between preoperative Vasostatin-1 (VS-1) plasma level and pathological features of aggressiveness was previously reported in patients with surgically resected nonfunctioning (NF) PanNET.

#3048 Somatostatin Analogs or Active Surveillance in Sporadic Non-Functioning Pancreatic Neuroendocrine Tumors
Introduction: Non-functioning (NF), sporadic pancreatic neuroendocrine tumors (pNETs) have usually an indolent behavior, but sometimes show an unpredictable aggressiveness. Surgery is the first-choice for localized tumors >2 cm. Unresectable or metastatic lesions expressing somatostatin receptors (SSTRs) are treated with Somatostatin analogs (SSAs). No evidence of SSAs efficacy exists in tumors ≤2 cm, for which active surveillance has been proposed.

#3058 Diagnosis and Assessment of Effectiveness of Surgical Resection of Small Bowel Neuroendocrine Tumours: The Roles of Circulating MicroRNAs
Introduction: MicroRNAs (miRNA) are small noncoding RNA molecules implicated in the pathophysiology of myriad neoplasms. Clinically useful biomarkers are needed in SB NET to ascertain disease aggressiveness, select treatment strategy, detect early recurrence and monitor response.

#59 Incidence and clinical significance of adrenal masses in patients with gastrenteropancreatic neuroendocrine tumors
Introduction: The widespread application of modern imaging modalities, mainly computerized tomography (CT) and magnetic resonance imaging (MRI), has revealed a 2-3% incidence of inadvertently discovered adrenal masses, the majority of which are non-functioning benign adrenal adenomas. In the presence of a known malignancy, such lesions have a more than 30% incidence of being metastases. As patients with gastrenteropancreatic neuroendocrine tumors (GEP-NETS) have mainly well-differentiated and slow-growing tumors and are subject to routine abdominal imaging for disease staging or during follow-up, it is important to study the incidence and significance of such lesions based on the recently introduced TNM classification system.

#138 The use of F-18-FDG-PET for patients with neuroendocrine tumors
Introduction: Neoplastic tissue exhibits high glucose utilization, which can be imaged by 18F-Fluorodeoxyglucose-positron emission tomography (FDG-PET). Whether FDG-PET is useful for neuroendocrine (NE) tumors, however, is questionable, due to the slow growth rate often observed in these tumors.
