#3524 Correlation of loss of ATRX expression with scintigraphic imaging studies in pancreatic neuroendocrine neoplasms

Introduction: Somatic inactivating mutations of ATRX (α thalassemia/mental retardation syndrome X-linked) in pancreatic neoplasms (pNENs) are associated with aggressive phenotype and are considered an independent prognostic factor of poor overall survival.

#2185 Nonfunctional Pancreatic Neuroendocrine Tumor (NF PNET) Imaging and Evaluation Using 18F-FDG and 68Ga- DOTANOC-PET/CT: Initial Data of a Prospective Study

Introduction: Predicting aggressive behavior of NF PNET still remains controversial. It is known that lymph node metastases are rare but possible also on small (1-2 cm) NF-PNET. Positive 18F-FDG-PET/CT avidity is associated with poor prognosis in NETs.
