Changes in the Frequency and Epidemiology of the Gastroenteropancreatic Neuroendocrine Tumors, Diagnosed in the University Hospital of Pleven, Bulgaria from the Period 2010 to November 2016


Introduction: During the recent years there has been an observed tendency of increased frequency of gastroenteropancreatic neuroendocrine tumors (GEP-NETs) all around the world due to the clinicians' improved knowledge about the diagnostic and treatment of these tumors. We have discovered a correlation between world tendency and the local tendency we have observed in the University Hospital of Pleven, Bulgaria from 2010 to November 2016.

Aim(s): The aim of our study is to check the validity of this tendency and the hypothesis that the popularization of NETs and the creation of specialized centers for these tumors leads to the increase of their frequency.

Materials and methods: This is a retrospective population based study about GEP-NETs using data from Regional Cancer Registry of Pleven for the observed period. It includes epidemiological information and data about the pathohistological characteristics.
