#3071 Hormonal Ectopic Secretion Syndromes Associated to Neuroendocine Neoplasia

Introduction: Neuroendocrine neoplasias (NEN) are able to produce and secrete bioactive peptides and cause distinct syndromes related to their biological effects. The outcome will depend on the oncological disease as well as the hormonal syndrome

#3046 Incidence of Neuroendocrine Neoplasms Reported in England 2015-2017

Introduction: Previously published UK Cancer Registry data showed incidence of Neuroendocrine Neoplasms rising between 2001 and 2015. This was higher than had been thought (Genus et al). We report more recent data with more accurate coding (ICD-O-3).

#2965 Molecular Signature of Rectal Neuroendocrine Neoplasia

Introduction: Rectal neuroendocrine tumors are rare neuroendocrine neoplasias (NEN). Little is known about prevalence and type of somatostatin receptor subtypes (sstr) expression and somatic mutations in relation to long-term clinical outcome.

#1630 The Positive Expression of PD-L1/PD-1 in Gastroenteropancreatic Neuroendocrine Neoplasias Correlates with Prognosis

Introduction: The incidence of Neuroendocrine Neoplasias (NENs) is increasing and their pathological characteristics, varied between races. However, the epidemiology of GEP-NENs in Chinese patients remains poorly characterized especially for the expression of important immune checkpoint protein PD1 and PD-L1.
