Mo1329 DIAGNOSTIC YIELD AND PREDICTORS OF ADEQUATE CYTOLOGY SAMPLING FOR KI67 ON ENDOSCOPIC ULTRASOUND GUIDED FINE NEEDLE ASPIRATION FOR GRADING OF PANCREATIC NEUROENDOCRINE TUMORS

Pancreatic neuroendocrine tumors (pNETs) account for 1-2% pancreatic tumors and require differentiation from carcinomas since their prognosis and management differ significantly. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is routinely employed in grading pNETs through estimation of Ki67 index on cytology samples. Therefore, obtaining sufficient cytology sample for accurate tumor grading is essential for prognostication and...
