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


Introduction: Classification of appendiceal neuroendocrine neoplasms (aNEN) changed significantly over the years and treatment algorithm remains a matter of debate.

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

Materials and methods: All pathology reports of aNEN received by the Belgian Cancer Registry, from 2010 to 2015, were reviewed for clinicopathological data. Tumors were reclassified to the WHO 2019 classification. In order to have an idea about the treatment performed, the data were linked with the administrative health database.
