#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.

#2962 90Y- and/or 177Lu-DOTATOC Re-Challenge in Patients with Progressive Neuroendocrine Tumors

Introduction: Most patients treated with PRRT will eventually progress. Previous studies indicated that repeated PRRT is feasible and promising.

#2014 Imaging of Advanced Medullary Thyroid Carcinoma with the CCK-2 Receptor Agonist 177Lu-PP-F11N – Preliminary Proof of the Principle within the “Lumed” Study

Introduction: Despite the introduction of new molecular targeted therapies, there is still an unmet need for an effective systemic therapy for advanced medullary thyroid carcinoma (MTC). Targeting the cholecystokinine-2 (CCK-2) receptor with radiolabeled gastrin analogues is a potential approach for radionuclide therapy of MTC.

#2003 Comparison of Glucagon-Like-Peptide-1 (GLP-1) Receptor PET/CT, SPECT/CT and 3T MRI for the Localisation of Insulinomas: Evaluation of Accuracy in a Prospective Crossover Imaging Study

Introduction: Benign insulinomas are the most prevalent cause of endogenous hyperinsulinaemic hypoglycaemia (EHH) in adults and due to their small size difficult to localise.
