Endocrine Paraneoplastic Syndromes in Patients with Neuroendocrine Neoplasms Abstract #2191

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.
Aim(s): To assess ePNS prevalence in a large cohort of NEN patients treated in EKPA-Laiko ENETS Center of Excellence, Athens, Greece.
Materials and methods: Records from 704 patients (335 female) with NENs (655 sporadic/ 49 familial) were reviewed for the presence of ePNS: 128 gastric, 35 duodenal, 257 pancreatic, 76 small intestinal, 12 colon, 29 rectal, 47 lung, 2 thymic, 44 unknown primary origin (UPO) and 16 of various other origin (ovarian, prostate, larynx).

#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.

#2145 Thrombotic Risk in Gastroenteropancreatic Neuroendocrine Tumors: A Single Centre Experience
Introduction: Neuroendocrine neoplasms (NENs) comprise a heterogeneous group of neoplasms associated with paraneoplastic syndromes. Venous thromboembolism (VTE) is a frequent complication in neoplastic patients and it is associated with increased morbidity and mortality. To date, there have been no specific studies in NEN, except for glucagon-secreting tumors
