#837 Does Biopsy Reliably Identify Grade In Gastroenteropancreatic Neuroendocrine Tumors?

Introduction: A new proliferation-based grading system has proved important in establishing prognosis and guiding therapy in gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Biopsies are often performed for grading but little is known about their reliability in assigning grade.

#836 Grade Increases In Gastroenteropancreatic Neuroendocrine Tumor Metastases Compared to the Primary Tumor

Introduction: The neuroendocrine tumor (NET) proliferation-based grading system (ENETS/WHO) has proved reliable for prognostic stratification of gastroenteropancreatic tumors (GEP). Although anecdotes have been published, no single study has evaluated whether grade changes between primary site and metastases.

#432 Ten Years of Gastroenteropancreatic Neuroendocrine Tumors (GEP-NETs): Evolution of Classification and Correlation with Follow-up in 50 Patients

Introduction: In the last decade, GEP-NET nomenclature has been twice reviewed. The 2000 WHO classification had poor prognostic power in well-differentiated (WD) neoplasms which led to the introduction of two new important parameters: grade and stage, by ENETS; the former became part of the new 2010 WHO classification.
