Prognostic relevance of a novel TNM classification system for upper gastroenteropancreatic neuroendocrine tumors

Abstract

The current results demonstrated the prognostic relevance of the newly proposed TNM classification system for foregut NETs with statistical significance for the subgroups of both the staging classification and the grading system. Thus, the new classification system provides a valid and powerful tool for prognostic stratification of GEP NETs in clinical practice and research.
