#3856 Duodenal gastric metaplasia and duodenal neuroendocrine neoplasms – More than a simple coincidence?

Introduction: Duodenal gastric metaplasia (DGM) is considered a precancerous lesion. No data are available regarding its possible role as a risk factor for duodenal neuroendocrine neoplasms (dNENs).

#3539 A rare presentation of duodenal neuroendocrine carcinoma

Introduction: Duodenal neuroendocrine neoplasms(dNEN) represent 2-3% of all gastro-intestinal NEN.Unlike other midgut NEN,they are usually diagnosed in a localized stage.

#3374 Gastric metaplasia and duodenal neuroendocrine neoplasms: True causality or simple coincidence?

Introduction: Duodenal neuroendocrine neoplasms (dNENs) are heterogeneous tumors, whose natural history is poorly known. Duodenal gastric metaplasia (DGM) is considered to be a precancerous lesion which is generally related to chronic inflammation as first sign. No data are available regarding its possible role as a risk factors for dNEN occurrence.

#2798 Risk of Pre-Operative Understaging of Duodenal Neuroendocrine Tumors at Conventional Imaging: When Surgery Becomes the First Choice

Introduction: Duodenal neuroendocrine neoplasms (dNENs) are heterogeneous tumors that can exhibit aggressive behavior, with loco-regional nodes and distant metastases. Pre-treatment staging is the basis for planning either surgical or endoscopic treatment.

#2138 Eterogeneity of Duodenal Neuroendocrine Tumors: A Multi-Centre Experience In Italy

Introduction: The optimal management of duodenal neuroendocrine neoplasms (dNENs) is unclear and endoscopic resection is increasingly performed instead of surgery.
