#2917 Quantification of Intratherapeutic SPECT/CT for Lutetium-177-DOTATOC PRRT in Neuroendocrine Tumors

Introduction: In PRRT for NET, feasibility of lesion uptake quantification in Lu-177-DOTATOC SPECT/CT for therapy monitoring remains unclear.

#2291 Somatostatin Analogs and mTOR Inhibitors as Radioprotectors or Radiosensitizers in Neuroendocrine Tumor Cells

Introduction: Neuroendocrine tumors (NETs) express somatostatin receptors that are currently utilized for diagnostic and therapeutic approaches. For peptide receptor radionuclide therapy (PRRT), somatostatin analogs are coupled to radionuclides like 90Y or 177Lu, which after injection are bound and taken up specifically by NETs. One hypothesis potentially explaining the discrepancies between expected result and observed outcome of PRRT might be that somatostatin analogs induce a G1 arrest in NET cells, thereby rendering them radioresistant.

#2080 Linked Colour Imaging Increases the Diagnostic Yield of Type 1 Gastric Carcinoid

Introduction: Type 1 Gastric carcinoid tumours (GCTs) are the most common neuroendocrine tumours of the stomach. Endoscopic diagnosis of Type 1 GCTs remains a challenge. White light endoscopy (WLE) and Narrow Band Imaging (NBI) have failed to demonstrate reliable endoscopic signs of carcinoid.

#1738 Sinonasal Neuroendocrine Small Blue Cell Tumour (SNBCT) Presenting with Bone Marrow Failure – A Very Rare Diagnostic and Therapeutic Challenge

Introduction: A 75 year old female presented with rapid onset right neck swelling and nasal bleeding. CT showed an infiltrative soft tissue mass involving the entire right nasal cavity and a lymph node mass in the right neck.
