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

#2798

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.

Aim(s): A group of surgically treated dNEN patients was evaluated to assess the concordance between the pre and post-surgery staging.

Materials and methods: Retrospective analysis of surgically treated dNENs patients. The pre-surgical TNM stage determined on the basis of radiological [computed tomography (CT) or magnetic resonance imaging (MRI)] and functional imaging (Gallium68 PET/Octreoscan©) was compared to the pathological TNM stage.
