#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.

#3045 Reliability and Agreement of Radiological and Pathological Tumor Size in Patients with MEN1-Related Pancreatic Neuroendocrine Tumors: Results from a Population-Based Cohort

Introduction: Pancreatic neuroendocrine tumors (pNETs) are the most lethal manifestation in patients with multiple endocrine neoplasia type 1 (MEN1). Tumor size is still regarded as the main prognostic factor and therefore used for surgical decision making.
