Exome sequencing analysis of 160 cancers arising in the periampullary region from 160 patients, 62 of these clearly arising from either the bile duct (n = 44) or the duodenum (n = 18) and 98 for which the epithelium of origin could not be clearly defined morphologically (AMPCA). This dataset contains summary data visualizations and clinical data from a sampling of 160 samples of ampullary adenocarcinomas...

Summary from the GEO: "Fibrolamellar hepatocellular carcinoma (FL-HCC) is a rare variant of HCC that most frequently affects young adults. Because of its rarity and an absence of preclinical models, the molecular biology of FL-HCC remains unclear. Our objective was to analyze chromosomal alterations and dysregulated gene expression in tumor specimens collected at a single center during two decades...
