#2804 Claudin-18 Is a Sensitive and a Specific Marker for Gastric Neuroendocrine Tumors

Introduction: Antibody-based cancer therapies are emerging as promising therapeutics in oncology, including one in clinical trials that targets claudin-18, a protein expressed in normal gastric epithelium and some gastric adenocarcinoma. We currently have no markers for gastric well-differentiated neuroendocrine tumors (NETs).

#2125 Subtype Classification and Clinicopathological Features of Gastric Neuroendocrine Neoplasms: 400 Cases of Multicenter Retrospective Analysis

Introduction: Definitions of Type 3 gastric NEN (g-NEN) in ENETS Guidelines 2012 and 2016 are ambiguous and controversial, so Four-type classification has been proposed in China.

#1741 Complete Remission of Hepatic Metastasis after Total Gastrectomy for a Gastric Carcinoid Tumor Type 1: A Case Report

Introduction: A 58-year-old woman was referred to our hospital for hepatic lesions and thickening of the walls of the stomach detected by abdominal CT scan. An upper GI endoscopy showed a lesion of the body of the stomach and the histopathologic exam documented a well differentiated NET. 68Ga-DOTATOC PET showed pathologic uptake in the stomach and in the liver (3 lesions). Circulating chromogranin A and gastrin were 596 ng/ml and 2283 pg/ml respectively

#1593 Role of SSA in the Management of Multiple Type 1 Gastric Neuroendocrine Neoplasms

Introduction: Type 1 g-NENs associated with autoimmune chronic atrophic gastritis have high risk of recurrence but rare metastasis. Most type 1 patients are managed by endoscopic approach. The clinical benefit of somatostatin analogues (SSA) for type 1 g-NENs is controversial.
