Neuroendocrine Tumors of the Gastrointestinal Tract with Second Primary Malignancy Abstract #635

Introduction: Neuroendocrine tumors of the gastrointestinal tract (NETs of GIT) are rare neoplasms frequently associated with synchronous or metachronous second primary malignancy (SPM). This phenomenon can be a result of an increasing incidence of NETs in patients who are examined for another primary malignancy. However, other theories suppose genetic predispositions or growth impact of different neuroendocrine peptides produced by NET.
Aim(s): To report on 25 patients with NET and SPM from a cohort of 233 patients with sporadic NET.
Materials and methods: Twenty-five patients with NET and synchronous and metachronous SPM were reviewed for primary site and characteristics of NET and associated SPM.
