Urinary 5-hydroxyindoleacetic Acid In Serotonin-Producing Neuroendocrine Tumors: Correlation with Disease Features and Patients' Survival Abstract #872

Introduction: Urinary 5-hydroxyindoleacetic acid (U-5HIAA) is a useful marker for serotonin-producing neuroendocrine tumors (NETs). Its prognostic role, however, is yet to be fully elucidated.
Aim(s): To evaluate U-5HIAA's role as a prognostic marker and its relation to disease features.
Materials and methods: Two-hundred and seven patients were included. Rates of flushing and bowel movements, chromogranin-A (CgA) levels and radiological data, were recorded. Patients were grouped, based on 5HIAA levels (Group 1: ≤1x upper limit of normal (ULN), 2: 1-5x ULN, 3: 5-10x ULN, 4: >10xULN).
