#2820 Efficacy of Peptide Receptor Radionuclide Therapy for Esthesioneuroblastoma

Introduction: Esthesioneuroblastoma (ENB) is a rare malignancy with limited therapeutic options when unresectable or metastatic. The overexpression of cell-surface somatostatin receptors in ENB is a potential molecular target making it amenable to peptide receptor radionuclide therapy (PRRT). High-level evidence supporting PRRT has been published for unresectable gastroenteropancreatic neuroendocrine tumours; however, data is limited for PRRT efficacy for ENB.

#2217 Prognostic Impact of CHOI Response Criteria Compared to RECIST in Grade 1-2 Advanced Pancreatic Neuroendocrine Tumors (CRIPNET-GETNE Study-NCT02841865)

Introduction: Response Evaluation Criteria In Solid Tumors (RECIST) are not presumably the most optimal option for predicting the benefit of antiangiogenic drugs in neuroendocrine tumors (NETs), given that tumor shrinkage is not frequent, and qualitative changes in tumor tissues are to be expected.
