Immunohistochemical analysis of CDO1 in colon cancer tissue microarray.

Expression level was indicated as -, absent or faint expression; +, moderate expression; ++, expression; +++, strong expression. CDO1 positivity (+) was counted in samples with over moderate expression. P values from Fisher’s exact test performed in Normal vs. adenocarcinoma in BC05118, adenocarcinoma in CO1922, or mucinous adenocarcinoma in CO1922. *P<0.05 considered significant. aCancer adjacent normal colonic tissue that excluded 5 cases of smooth muscle and 4 cases of disrupted tissue (not determined). bA case (fibrous tissue) was excluded. cTen cases of adenocarcinoma without grade and two cases squamous cell carcinoma were excluded, but 38 cases of mucinous adenocarcinomas were included. dTumor grade was not considered.
