#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).

#3828 Role of endoscopic resection margin (R1) in the clinical outcome of patients with neuroendocrine neoplasia

Introduction: Endoscopic resection margin R1 (ER1) describes neoplasia presence at lateral and/or deep margin. Highest rate of R1 resection occurs in duodenal NENs (d-NENs) where advanced resection techniques [endoscopic submucosal dissection (ESD); full thickness resection (EFTR)], are more difficult to apply. In gastric (g-NENs) and rectal NENs (r-NENs), due to favourable anatomy, ESD or EFTR obtain lower rates of R1 resection.

#3464 Digital quantification of somatostatin receptor subtype 2 immunostaining in pancreatic neuroendocrine tumors and GH-secreting adenoma: A validation study

Introduction: Somatostatin receptor subtype 2 (SST2) immunostaining (IHC) is routinely performed in neuroendocrine tumors (NET) and recommended in acromegaly guidelines. No univocal score of SST2 IHC has been validated yet.

#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.
