#4614 Rare diagnosis of intrapancreatic accessory spleen mimicking PanNET

Introduction: A 44-year-old woman with hypertension and an autoimmune thyroid disease. With a positive family history of pancreatic and oesophageal cancer. Referred to our clinic for an incidental finding of a tumour in the tail of the pancreas on abdominal ultrasound by a surgeon.

#4151 Identifying potential tumor drivers through integration of gene expression and DNA copy number in SI-NET

Introduction: The genetics of small intestine neuroendocrine tumors (SI-NETs) remains poorly understood. To date, only CDKN1B has been found recurrently mutated, in approximately 9% of cases. On the contrary, DNA copy number alterations are found in a majority of cases. The most frequent aberration is heterozygous loss of chromosome 18. In addition, loss of chromosome 11, and gains on chromosomes 4, 5 and 14 are common. The cellular mechanisms through which these alterations drive tumor development are unknown.

#3178 Dual 68Ga-DOTATATE and 18F-FDG PET/CT in patients with gastroenteropancreatic neuroendocrine neoplasms: A multicentre, validation study of the NETPET score in 239 patients

Introduction: PET/CT using 68Ga-labelled somatostatin analogues and 18F-FDG have both been used to image neuroendocrine tumors. Our previously published data proposed the NETPET score to characterise findings on dual PET.

#2985 Peptide Receptor Radionuclide Therapy (PRRT) Outcome Prediction in Neuroendocrine Tumors (NET): Could Radiomic Features Analysis of 68Ga-DOTATOC PET/CT Have a Roll?

Introduction: The PRRT is an effective treatment for NET, but the selection of a good candidate is a very important step.

#1309 Dual 18F-Fluorodeoxyglucose/68Gallium DOTATATE (FDG/DOTA) PET Predicts Overall Survival in Neuroendocrine Tumours (NET)

Introduction: 68Ga-DOTATATE (DOTA) and FDG PET have been utilised in NETs to aid diagnosis, prognostication and guide management. FDG PET avidity is associated with poor prognosis, but the prognostic significance of dual FDG/DOTA grading has not been explored.
