Association between neuroendocrine tumors biomarkers and primary tumor site and disease type based on total 68Ga-DOTATATE-Avid tumor volume measurements

Objective To determine the association between neuroendocrine tumor (NET) biomarker levels and the extent of disease as assessed by 68 Ga DOTATATE PET/CT imaging. Design A retrospective analysis of a prospective database of patients with NETs. Methods Fasting plasma chromogranin A (CgA), neuron-specific enolase (NSE), gastrin, glucagon, vasoactive intestinal peptide (VIP) and pancreatic polypeptide (PP), and 24-h urinary 5-hydroxyindoleacetic...
