#3835 Druggable growth dependencies and tumor evolution analysis in patient-derived organoids of neuroendocrine cancer

Introduction: 28% of low-grade neuroendocrine tumors (NETs) present at advanced stages and are unresponsive to therapy, pointing to a gap in our understanding of how these tumors arise and progress.

#3559 Novel patient-derived tumor organoid models reveal growth-factor dependencies in neuroendocrine tumors and serve as a platform for neuroendocrine cancer research

Introduction: Neuroendocrine neoplasms (NENs) comprise neuroendocrine tumors (NETs) and neuroendocrine carcinomas (NECs). While NETs are well-differentiated and progress slowly, NECs are poorly differentiated and have a poor prognosis. Irrespective of subtype, treatment options for patients with unresectable, relapsed, or metastasized NENs are limited, in part due to lack of accurate models to study these diseases.

#3280 A patient derived organoid model of neuroendocrine neoplasms enables long-term growth in vitro of low grade tumors and reveals therapeutic vulnerabilities

Introduction: A paucity of in vitro and in vivo models has limited the study of neuroendocrine neoplasms (NENs).

#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.

#3049 Organoid Models of Neuroendocrine Cell Growth and Tumorigenesis

Introduction: A paucity of in vitro and in vivo models has limited the study of Neuroendocrine neoplasms (NENs). Moreover, little is known about normal neuroendocrine (NE) cells and how they contribute to NEN formation.
