Twenty pancreatic primary tumors were purchased from Asterand, Inc (Detroit, MI). The panel included 13 adenocarcinomas (stage I-IV), 5 pancreatic endocrine tumors and 2 benign pancreatic adenomas. Four of the 20 pancreatic tumor tissue samples had matched normal adjacent pancreatic tissue samples. Patient age ranged from 23 to 77 years. All samples were freshly frozen and collected before the initiation of any cancer treatment. Tumor samples were macrodissected to remove normal tissue, and tumor purity in all samples was greater than 85%. Normal samples were macrodissected to remove non-glandular tissue.
