Tumor biology, not tissue of origin, drives outcomes following resection of duodenal/ampullary and pancreatic neuroendocrine tumors.

B Methods: b A prospectively maintained; single institution database of all pancreatic resections was queried for patients undergoing surgical resection for a neuroendocrine tumor. Patients in the DANETs group were significantly older (60.0yr vs 59.6yr; p = 0.018), had higher grade tumors (22.0% G2 or G3 tumors vs. 9.3%; p = 0.019), and had more node positive resections (70.0% vs. 36.9%; p < 0.001).
