Abstract excerpt

<p>Introduction: Non-ampullary duodenal epithelial tumors with a gastrointestinal mixed phenotype (mixed-type NADETs) have not been thoroughly analyzed. We aimed to elucidate the clinicopathological and endoscopic characteristics of mixed-type NADETs. METHODS: A total of 229 NADETs from 218 patients collected from February 2010 to December 2023 were analyzed. Based on immunohistochemistry for MUC5AC, MUC6, MUC2,...
