Correlation of Serum Plasma Chromogranin A with Survival and Disease Features in Patients with Gastroenteropancreatic Neuroendocrine Tumors. First Results in a Large Database in Argentina. ARGENTUM GROUP.

#1147

Introduction: The plasma chromogranin A (CgA) is the best general biomarker in gastroenteropancreatic neuroendocrine tumors (GEP-NETs). CrA levels are elevated in a variety of GEP-NETs and are used to aid in diagnosis, prognosis, and monitoring of treatment effects in this population.

Aim(s): To correlate the baseline value and change CrA levels with patient survival and tumor response in GEP-NETs.

Materials and methods: Serial CgA determinations were performed in 280 patients in different Centers in our Country. CgA level was analysed for correlation with the patient´s clinical outcome, looking for survival as a primary end-point. CgA was measured at baseline and at regular intervals after diagnosis.
