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

#126 Assessment of the proliferation marker Ki-67 by endoscopic ultrasound guided-Fine Needle Aspiration (EUS-FNA) in pancreatic endocrine tumors: A comparative analysis with histology of the surgical specimen
Introduction: Assessment of the proliferative index by Ki-67 immuno-labelling is an important prognostic parameter for the biologic behavior of digestive neuroendocrine tumors, usually established on the histological specimen obtained after surgery or macro-biopsy. However, small pancreatic endocrine tumors (PET) are more and more often recognized by CT/MRI and diagnosed by EUS. The value of Ki-67 labelling index (Ki-67-LI) on fine needle aspiration (FNA) is not well-established in this setting, although regularly assessed.

#518 CK19 and KIT Immunostaining is a Useful Adjunct to Ki-67-Based Grading of Pancreatic NET: A Study on Matched Cytological and Histological Samples
Introduction: Pancreatic neuroendocrine tumors (NET) are rare neoplasms. Recent evidence suggests that Ki-67 staining predicts their behavior. Even more recently, a prognostic role has been proposed also for CK19 and KIT. This panel might guide patient management. CK19 and KIT have not yet been evaluated on NET on Fine needle aspiration samples (FNAs).

#859 Pancreatic Neuroendocrine Tumors (PNETs): Role of Endoscopic UltraSound-Fine Needle Aspiration (EUS-FNA) and Accuracy of Ki-67 Measurement on Cytological Specimens
Introduction: The role of EUS-FNA in preoperative diagnosis and grading of pNETs is well-established, but it is unclear how Ki-67 expression on cytological specimens obtained by EUS-FNA reflects the value found on surgical specimens.
