Natural History of Type 1 Gastric Carcinoid (gNENs) and Risk of Adenoma/Adenocarcinoma in Endoscopic Surveillance Programme

#1890

Introduction: Patients with gNENs & autoimmune gastritis are exposed to 2 malignant risks: 1)transformation of gNENs, felt to be low & guidelines advocate either resection of all lesions or selective endoscopic mucosal resection(EMR) of larger lesions; 2)ill-defined risk of gastric adenoma/adenocarcinoma.

Aim(s): The aim is to assess the adequacy of surveillance in detecting disease progression.

Materials and methods: Retrospective analysis of patients with type 1 gNENs(2005 to 2016) where selective EMR used for gNENs ≥10mm & carefully appraised for adenocarcinoma. Disease progression defined as gNENs requiring EMR or surgery.
