Epidemiology and Classification of Gastroenteropancreatic Neuroendocrine Neoplasms Using the WHO 2010 Criteria: A Cohort Study in a Defined Norwegian Population.

#1121

Introduction: Incidence figures of gastroenteropancreatic neuroendocrine neoplasia (GEP-NEN) still remain uncertain.

Aim(s): We evaluate the epidemiology of GEP-NEN in a well-defined Norwegian population.

Materials and methods: Patients diagnosed between 2003 and 2014 with GEP-NEN at Stavanger University Hospital, the only hospital for a population of 350 000, were included. A cross-linked search for appropriate diagnostic codes (ICD-9/10), morphology codes (SNOMED) and specific imaging (e.g. SRI) was used to identify eligible patients. Incidence rates were calculated by gender and age groups matched for population by Statistics Norway. Classification and staging was done according to the WHO 2010 criteria.
