FIGURE 3

Results of Cdx2 immunohistochemistry in adenocarcinomas. Immunohistochemical staining was graded 0–4+ based on the percent of cells showing nuclear staining for Cdx2. Colorectal adenocarcinomas had the greatest percentage of cases showing strong diffuse Cdx2 staining (3–4+), followed distantly by ovarian, ampullary, and gastroesophageal adenocarcinomas.
