#3586 Grading diagnostic accuracy of EUS Tissue Acquisition in pancreatic neuroendocrine tumors: A systematic review and meta-analysis

Introduction: Pancreatic neuroendocrine neoplasms (PanNENs), are a form of neoplasms arising from cells of the endocrine and nervous systems. Grading (G) is one of the most important decisional factor for therapy as is associated with prognosis, overall survival and disease free survival decrease. Endoscopic ultrasound fine needle-aspiration/biopsy (EUS-FNA/B) is the gold standard for diagnosing PanNENs and Ki67 evaluation, but data regarding accuracy and concordance with post-surgical histological examination are scanty and heterogeneous.
