#3080 Impact of Multimodal Perioperative Treatment in Patients with Resected Non-Metastatic Grade 3 Neuroendocrine Neoplasms (NEN G3)

Introduction: Patients with grade 3 neuroendocrine neoplasm (NEN G3) have a limited prognosis. Even in a non-metastatic stage, the risk of recurrence after surgery is high. Multimodal perioperative treatment, including chemotherapy and/or radiotherapy in an adjuvant or neoadjuvant setting, has improved the prognosis in numerous tumor entities; however, it has not been systematically evaluated in NEN G3 so far. Nevertheless, perioperative chemotherapy is generally recommended in most current treatment guidelines for NEN G3.

#2989 Different Social Media Neuroendocrine Tumor Indexing Strategies Used by Physicians and Advocacy Groups

Introduction: The use of Twitter to disseminate medical content has increased over the last decade. Although Twitter activity by oncologists is clustered around international conferences, advocacy groups have different temporal social media patterns. Furthermore, given the non-standardized method of indexing tweets using Twitter hashtags, it can be difficult to follow the full breadth of a topic.

#2984 AGTR1 Is Overexpressed in Neuroendocrine Neoplasms, Regulates Secretion and May Serve as a Target for Molecular Imaging and Therapy

Introduction: Peptide receptor targeting has proven to be a pivotal tool for diagnostic imaging and radioligand therapy of neuroendocrine neoplasms (NENs), which frequently express somatostatin receptors (SSTRs) on their cell surface. However, up to 30 % of NEN patients do not benefit from SSTR-based approaches, others develop a resistance.

#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.

#2682 PAK4-NAMPT Dual Inhibition as a Novel Strategy for Therapy Resistant Pancreatic Neuroendocrine Tumors

Introduction: Pancreatic neuroendocrine tumors (PNET) remain an unmet clinical need. In this study, we show that targeting both nicotinamide phosphoribosyltransferase (NAMPT) and p21-activated kinase 4 (PAK4) could become a synthetic lethal strategy for PNET.
