#2815 Unexpected High Rate of Metastases in Type 1 Gastric Neuroendocrine Neoplasia

Introduction: Gastric neuroendocrine neoplasms (gNEN) represent about 7.5% of gastroenteropancreatic NEN (gepNEN), classified in: type 1 (70-80%), related to autoimmune gastritis, type 2 (5%), related to Zollinger-Ellison syndrome in multiple endocrine neoplasia 1 and type 3 (15-20%), in absence of hypergastrinemia or mucosal atrophy.

#844 Variation Between Chromogranin A Assays in the Diagnosis of Gastric Carcinoid Type 1

Introduction: Chromogranin A (CgA) is not very accurate for the diagnosis of gastric carcinoid type1 (GC1). Clinical interpretation of CgA results may be affected by the heterogeneity between CgA assays. The commercial CgA assay, DAKO (DAKO, Denmark A/S, Glostrup, Denmark) is an ELISA which recognizes a 23 kD C terminal fragment of CgA; the Imperial Supra-regional Assay Service radioimmunoassay (SAS Hammersmith Hospital, Imperial College, London) is a competitive radioimmunoassay raised against the whole pancreastatin molecule.

#621 Occurrence of Type 1 Gastric Carcinoid In Patients with Autoimmune Chronic Atrophic Gastritis

Introduction: The actual incidence of type1 gastric carcinoids (GC1) as a long-term complication of chronic autoimmune atrophic gastritis (CAAG) remains to be clarified as studies are few.
