Incidence of Secondary Neoplasia in Patients with Neuroendocrine Tumor: An Analysis of the SwissNET Database

#821

Introduction: NET are believed to be associated with an increased risk for secondary neoplasia. Previous studies suggest incidence rates between 7% and 46%.

Aim(s): To determine the incidence rate and related mortality based on the Swiss NeuroEndocrine Tumour registry (SwissNET).

Materials and methods: Two-hundred and eighty-five men (55%) and 237 women (45%) with sporadic NET were included. Four-hundred and fifteen NET were localized in the GI-tract (79.5%), 55 in the lung (10.5%). In 40 cases (8%) primary site was unknown or at other sites (12 patients, 2%). Median age at diagnosis was 59 years, median follow up 318 days.
