#4340 Predominant volumetric phenotype in dual PET and overall survival in NENs

Introduction: Dual 18F-FDG/68Ga-DOTATATE PET can predict NEN prognosis and guide treatment choice. However, research to date (such as the NEPTET score) has focused on the dual PET phenotype of single-point lesions rather than of the total disease volume.

#3952 Peptide Receptor Radionuclide Therapy (PRRT) in the management of patients with ectopic Cushing’s syndrome due to metastatic gastroenteropancreatic neuroendocrine neoplasia (GEPNEN): A single centre experience

Introduction: Metastatic GEPNEN can cause ectopic Cushing’s syndrome (ECS). ECS is highly morbid and often refractory to medical therapy. Bilateral adrenalectomy (BA) carries risk and long-term morbidity. Patients (pts) unsuitable for surgery have dismal outcomes. Peptide receptor radionuclide therapy (PRRT) is a rational option for hormone control in ECS caused by NEN with high somatostatin receptor (SSTR) expression yet detailed case series to guide its use are lacking.

#3567 Metastatic mixed VIPoma/PPoma-induced diarrhoea causing renal failure

Introduction: Pancreatic neuroendocrine tumors (pNETs) are rare, but despite better prognosis than other pancreatic tumors, their presentation is often occult. VIPomas are a further subtype secreting vasoactive intestinal peptide (VIP). Associated symptoms are particularly non-specific, with watery diarrhoea and electrolyte disturbance which mimics less sinister pathology. Consequently, this presentation is often overlooked resulting in tumor progression and delayed diagnosis, hindering effective management.

#3010 International Validation of a Nomogram to Predict Recurrence after Resection of Grade 1 and 2 Pancreatic Neuroendocrine Tumors

Introduction: A prediction model to predict recurrence within 5 years after surgery for nonfunctional pancreatic neuroendocrine tumors (PanNets) was recently published. This model includes WHO tumor grade, lymph node status and perineural invasion as predictors.
