Pancreatectomy for NET: External Evaluation of WHO 2017 Grading System (PanTEN)
Outcome After Pancreatectomy for Neuroendocrine Tumor and Evaluation of the WHO 2017 Grading System: a Retrospective Multicentric Analysis of 138 Consecutive Patients.
Aim: The aim of this study was to investigate the clinicopathological factors and to evaluate the prognostic accuracy of the new World Health Organization (WHO) 2017 grading system in pancreatic neuroendocrine tumor (PanNET) patients.
Methods: Data collected between 1997 and December 2017 were analyzed. Histological grading and staging was based on the WHO 2017 grading system. Outcome after surgery and predictors of overall survival (OS) and disease free survival (DFS) were evaluated.
