#3048 Somatostatin Analogs or Active Surveillance in Sporadic Non-Functioning Pancreatic Neuroendocrine Tumors

Introduction: Non-functioning (NF), sporadic pancreatic neuroendocrine tumors (pNETs) have usually an indolent behavior, but sometimes show an unpredictable aggressiveness. Surgery is the first-choice for localized tumors >2 cm. Unresectable or metastatic lesions expressing somatostatin receptors (SSTRs) are treated with Somatostatin analogs (SSAs). No evidence of SSAs efficacy exists in tumors ≤2 cm, for which active surveillance has been proposed.

#2960 Epidemiological Characteristics of Neuroendocrine Tumors: A Retrospective Analysis of a Single Centre

Introduction: Neuroendocrine tumors (NETs) are a small heterogeneous group of cancers, developing from the neuroendocrine system. NETs may include functional or non-functional tumors; moreover, they may be familial and have further associated tumors.

#2852 Diagnostic Accuracy of Endoscopic Ultrasound-Fine Needle Aspiration (EUS-FNA) in the Evaluation of Pancreatic Neuroendocrine Neoplasms (PNEN) Grading

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

#2798 Risk of Pre-Operative Understaging of Duodenal Neuroendocrine Tumors at Conventional Imaging: When Surgery Becomes the First Choice

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.

#2792 Post-Transplant Recurrence of Neuroendocrine Tumors

Introduction: Recurrence after liver transplantation (LT) for metastases from NET is observed in 30-50% of cases at 5 years after LT but management is individualized
