#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.

#3057 Epidemiological Features of Patients with NeuroEndocrine Neoplasms (NENs): Preliminary Results of an Observational Study by the Hellenic Society of Medical Oncology (HeSMO)

Introduction: NENs are rare tumors and can grow in almost all tissues. Regardless histological, molecular and imaging characteristics that are indicative of the primary origin, a significant percentage remain of unknown primary.

#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.

#3028 Pancreatic Neuroendocrine Neoplasms: Dissecting the Molecular Heterogeneity

Introduction: Pancreatic neuroendocrine neoplasms (PNENs) are a group of rare but biologically and clinically heterogeneous neoplasms with variable patient outcomes. Little is known about the molecular differences between PNENs and the biologic significance of such divergence.
