#2284 The Association between Gastrin and Glucose Serum Concentration in Hypergastrinemic Patients with Gastric Neuroendocrine Tumors Type 1 and ECL-Cells Hyperplasia

Introduction: There is previous data demonstrating that elevated gastrin levels could exert some effect potentiating the glucose-induced insulin secretion.

#2242 Diagnostic Utility of Ki-67 as a Mean to Predict the Uptake of Functional Imaging Modalities in Patients with Neuroendocrine Neoplasms

Introduction: Functional imaging with FDG-PET and somatostatin receptors scintigraphy (SRS), play a key role in the diagnosis, treatment and follow-up of patients with neuroendocrine neoplasms (NENs). The proliferative index, ki67, is a reliable pathological marker for grading.

#1935 Prevalence of Pancreatic Neuroendocrine Neoplasms with Serotonin Secretion

Introduction: Pancreatic neuroendocrine neoplasms (pNENs) are rare neoplasms and represent 1-2% of all pancreatic neoplasms. These tumors can secrete a variety of hormonally active substances producing distinct clinical symptoms, or can be clinically non-functioning. Pancreatic NENs that secrete serotonin are extremely rare, but their prevalence has not been explored adequately.
