The size of well differentiated pancreatic neuroendocrine tumors correlates with Ki67 proliferative index and is not associated with age

Background Concerns exist about a conservative management of well-differentiated nonfunctioning small pancreatic neuroendocrine tumors (NF-PanNET) in young patients and when preoperative Ki67 proliferative index is ≥3%. Aim To evaluate an association between age, tumor size and grading in patients with sporadic NF-PanNET who underwent curative resection. Methods Patients who underwent surgery for sporadic NF-PanNET (excluding G3) were...
