#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.
