Figure 2.
Mutation and CNV profiles in non‐ampullary duodenal adenomas and intramucosal adenocarcinomas. Upper panels show histological types, Vienna classification, and CIMP status. Middle panels show summarized results for targeted sequencing of cancer‐related genes in tumors with the indicated histological types. Lower panels show frequently detected CNVs. Frequencies of CIMP status as well as mutations and CNVs in respective genes are shown on the right. CIMP, CpG island methylator phenotype; GCA, gastric‐type intramucosal adenocarcinoma; PGA, pyloric gland adenoma; SCA, small intestinal‐type intramucosal adenocarcinoma; SHA, small intestinal‐type high‐grade adenoma; SLA, small intestinal‐type low‐grade adenoma.
