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

#3856

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).

Aim(s): To assess the prevalence of DGM in a cohort of dNENs.

Materials and methods: Subgroup analysis of a retrospective study including dNEN patients who underwent surgical resection between 2000 and 2019, observed at eight Italian tertiary referral centers.
