#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.

#2992 The PanNENomics Project: A Call for an International Collaborative Effort Built on the Success of the LungNENomics Project

Introduction: Neuroendocrine tumors are rare understudied diseases at the molecular level, especially those occurring in sites outside the lung and the gastrointestinal track. This lack of knowledge has strong implications for the clinical management of these diseases (Rindi et al. Mad Pathol 2018).
