#2191 Endocrine Paraneoplastic Syndromes in Patients with Neuroendocrine Neoplasms

Introduction: Endocrine paraneoplastic syndromes (ePNS) result from production of bioactive substances from tumours not related to their expected tissue of origin. Neuroendocrine neoplasms (NENs) have been associated with ectopic secretion of several hormones, but the prevalence of ePNS has only been described in a small number of studies.

#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.

#1145 The Association Between Gastrin and Glucose Serum Concentration

Introduction: Gastrin is an early incretin candidate, since it is released by oral glucose and potentiates the glucose- induced insulin secretion. It has been shown that only in hypoglycemic or hyperglycemic conditions gastrin release is influenced by changes in blood glucose and insulin concentrations.
