Most colorectal cancers are ck7 negative and ck20 positive, making the combination of these cytokeratins an excellent biomarker combination. Most colorectal cancers (crcs) show positive immunohistochemical (ihc) staining for ck20 and negative staining for ck7.however, in clinical settings, some crcs show positive ihc staining for ck7, and the clinicopathological significance of this needs to be studied. The ck20 / ck7 immunoprofile of colorectal adenocarcinoma has been described in studies, which have mostly lumped colonic and rectal tumors together.

Cdx2 is a marker of enteric differentiation and is positive in >90% of colorectal adenocarcinomas (20,21). Cytokeratin 20 is often used in conjunction with ck7 and other antibodies in distinguishing colon carcinomas (ck20+) from ovarian, pulmonary, and breast. Normal tissue was more likely to be negative for ck7 (both ck20+/ck7− and ck20−/ck7−) (p <.0001). In immunohistochemistry, antibodies to ck20 can be used to identify a range of adenocarcinoma arising from epithelia that normally. Keratin 20 is a type i cytokeratin.it is a major cellular protein of mature enterocytes and goblet cells and is specifically found in the gastric and intestinal mucosa. Of importance in these cases was the fact that the primary tumor was a poorly differentiated adenocarcinoma (5 cases), or in the cases with medium differentiation, the tumor was a. Cdx2, a critical nuclear transcription factor for intestinal development, is expressed in intestinal epithelium and. The most common immunophenotype of colorectal adenocarcinoma is positivity for ck20 and negativity for ck7, which is a relatively specific staining pattern for colorectal origin. In this group, the ck20+/ck7 negative (−) pattern was highly characteristic for colorectal localization of the primary tumor, having been observed 17 of 21 of the cases (81%). The combined expression of ck7/ck20 is the most widely used marker. In conclusion, the ck7 and ck20 expression patterns in primary gastric carcinomas vary considerably, and those in colorectal carcinomas are associated with histologic grade and tumor location.
