Second Primary Tumor in Patients with Gastroenteropancreatic Neuroendocrine Tumors (GEPNETs): Data From a Retrospective Observational Unicentric Study

#544

Introduction: It is known that GEPNETs are associated with a high incidence of second primary tumors, especially in the context of inherited syndromes and synchronous injuries to the intestine.

Aim(s): To assess the percentage of patients with GEPNETs who develop a second primary tumor with different origin and histology.

Materials and methods: We present a retrospective analysis of 166 patients (mean age 65 years, 55% males and 5% with inherited syndrome) attended in our Medical Oncology Department between 2007 and 2011. The tumor types were: GENET 58% and PNET 42%. The tumor stages were: I 33%, II-III 16% and IV 51%.
