We sought to molecularly classify ampullary adenocarcinomas in comparison to known adenocarcinomas of the pancreas, extrahepatic bile duct, and duodenum by gene expression analysis. We analyzed 32 fresh-frozen resected, untreated periampullary adenocarcinomas (8 pancreatic, 2 extrahepatic biliary, 8 duodenal, and 14 ampullary) using the Affymetrix U133 Plus 2.0 genome array.http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-39409http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-39409/samples/
