Fine-needle aspiration biopsy of pancreatic neuroendocrine tumors: Correlation between Ki-67 index in cytological samples and clinical behavior.


BACKGROUND Mitotic count in hematoxylin-eosin stained slides and Ki-67 index allow stratification of patients for prognosis and therapeutic decision making in pancreatic neuroendocrine tumors (PNETs). However, the utility of Ki-67 determination in cytological material and its association to PNET prognosis are under discussion. METHODS We have… (More)
