24 Hour Urinary 5-Hydroxyindoleacetic Acid Levels in Patients with Non-Functioning Pancreatic Neuroendocrine Tumors Abstract #2219

Introduction: The secretion of urinary 5-Hydroxyindoleacetic Acid (u5-HIAA) by non-functioning PNETs (NF-PNET) has rarely been reported, and the data on the association between u5-HIAA levels and disease burden is scant.
Aim(s): To assess u5-HIAA levels in patients with NF-PNETs.
Materials and methods: A retrospective analysis of a prospective study, including patients with gastro-entero-pancreatic NET, with biochemical biomarkers and imaging follow-up. Tumor burden was determined by measuring 68Ga-DOTATATE-avid tumor volume using a SUVmax threshold.

#1434 CA19-9 As a Prognostic Biomarker in Pancreatic Neuroendocrine Tumors
Introduction: Carbohydrate antigen19-9 (CA19-9) is generally not considered as a biomarker in pancreatic neuroendocrine tumors (pNETs) since most pNETs present with normal range of CA19-9.

Introduction: 8-20% of patients with VHLD develop PNETs. However, there are no markers for PNETs progression in VHLD patients. The type of mutation in VHL gene is associated with clinical phenotype of VHLD.
