Incidence of Rectal NEN and Adherence to Pathology Classification Rules and Treatment Guidelines: Results of the Population Based Cancer Registry in Belgium


Introduction: Classification of rectal NEN (rNEN) changed significantly over the years.

Aim(s): We aimed to have complete epidemiological data on the incidence of rNEN in Belgium and investigated the evolution in reports and treatment decisions.

Materials and methods: All pathology reports of rNEN received by the Belgian Cancer Registry, during 2004-2015, were reviewed for clinicopathological data. Classification was adapted based on the WHO 2019 classification. In order to have an idea about the treatment management, the data were linked with the administrative healthcare database.
