#4649 Claudin 18.2 overexpression in gastric neuroendocrine tumours

Introduction: Claudin 18.2, is a tissue biomarker physiologically expressed in both healthy gastric mucosa and gastric adenocarcinoma which represents a novel therapeutic target advanced gastric cancer. Various other cancers showed some overexpression of claudin 18.2 opening potential opportunities to agnostic targeted therapy. However, data about claudin 18.2 expression in NENs are poor with only an Eastern study showing higher rate of claudin 18.2 positivity in GEP-NENs, mainly from gastric primary site (27.8%).
