To characterize the expression pattern of FLI1 in gastric mucosa without intestinal metaplasia, mucosa with intestinal metaplasia (IM), dysplasia, and gastric adenocarcinoma, we stained and analyzed tumor microarrays (TMAs) and traditional whole tissue sections from 98 patients by H&E stains and IHC (see Table 1 for summary). This evidence concerns the gene FLI1 and gastric adenocarcinoma.
