Staging Classification Comparison of Resected Pancreatic Neuroendocrine Tumors (pNETs) Utilizing the National Cancer Database (NCDB)

#1908

Introduction: The staging classification of pNETs remains a matter of debate and no obvious superior system has emerged.

Aim(s): To compare 3 current pNET staging classifications using NCDB data from 2004-2014 in patients (pts) who have undergone resection.

Materials and methods: Pts with pathologically confirmed pNET, complete data allowing restaging by AJCC (7th ed), ENETS, and mENETS classifications, who had resection of the primary tumor were included (N=4072). Overall survival (OS) was analyzed utilizing Kaplan-Meier curves, log-rank tests were used to compare stage systems. Cox proportional hazards methods were used to control for age, sex, grade, tumor location, functional status, stage, and year of diagnosis.
