#3557 Final analysis of Chromogranin A for neuroendocrine tumor diagnosis in Chilean patients: An updated case-control study

Introduction: Neuroendocrine tumors (NETs) are highly heterogeneous and differ geographically. Serum chromogranin A (CgA) is the most used biomarker for NET diagnosis, with a sensitivity of 63-100% and specificity of 95-98% with a cutoff value of 108 ng/mL. Recent studies worldwide have reported varying frequencies of NET patients with high CGA at diagnosis, suggesting that the cutoff value may differ according to each population.
