Is Ki67 Index in Biopsy Tissue Truly Reflect Grading of Pancreatic Neuroendocrine Neoplasm? Abstract #1852

Introduction: Ki67 index is essential for progression and treatment of pancreatic neuroendocrine neoplasm (pNEN). For advanced pNEN patient(pts), Ki67 scoring by core/fine-needle biopsy is used to evaluate pNEN pts’ grade.
Aim(s): we retrospectively analyzed Ki67 index difference between surgery and biopsy tissue of pNEN pts.
Materials and methods: pNEN pts who had both surgery and core/fine-needle biopsy pathological results was performed in single Center.
