Diagnostic Accuracy of Endoscopic Ultrasound-Fine Needle Aspiration (EUS-FNA) in the Evaluation of Pancreatic Neuroendocrine Neoplasms (PNEN) Grading

#2852

Introduction: Prognosis of pNENs depends on staging and grading, based on the cyto-histological Ki67 labelling; EUS-FNA is considered the gold standard technique to obtain it in pre-therapeutic setting

Aim(s): The aim was to establish diagnostic accuracy of preoperative EUS-FNA Ki67 evaluation in a cohort of pNEN patients

Materials and methods: This is a retrospective study from a prospectively collected database on patients who underwent surgery for pNENs from 2006 to 2019 and EUS-FNA Ki67 labelling.EUS-FNA and surgery Ki67 (eKi67 and sKi67) values and grading were compared and diagnostic accuracy of EUS-FNA was evaluated with sKi67 as gold standard. eKi67/sKi67 correlation was evaluated by Pearson’s index
