| Abstract | ||
| Background: Colorectal carcinoma is common in Northwest Europe, North America, and other Anglo-Saxon areas, while it decreases in number in Africa, Asia, and some parts of South America,There are many immunohistochemical markers react to colonic tissue, the large majority of colorectal carcinomas are positive for mucin stains. Colorectal adenocarcinomas are invariably positive for cytokeratin (CK), Reactivity for CEA is also the rule; as a matter of fact, failure to detect CEA in an adenocarcinoma of makes a colo-rectal site of origin seems to be unlikely, and many other markers that could claimed in colorectal tumors, a one marker that may has a role in staining colorectal tumors is HepPar-1 which is a monoclonal antibody that reacts to an as yet unidentified cytoplasmic marker of normal and neoplastic hepatocytes, which could be expressed in neoplastic or non-neoplastic colorectal tissue. Objectives: to see the expression of HepPar-1 (cytoplasmic marker of normal and neoplastic hepatocytes) in colorectal cancer. Patients and methods: Fifty-eight cases (49 with colorectal carcinoma, 9 cases on non-malignant colorectal tissues) male and females depending on records, the study is conducted in GIT specialized hospital in medical city / department of histopathology – Baghdad city during period from 1/10/2016 to 1/4/2017. Results: cases were studied, the positivity in our study of the cases was (8.2%), and none of the control "non-neoplastic" cases express this marker. No significant statistical correlation was found between HepPar-1 expression and the tumor grade, site, age or sex, (P values >0.05). Conclusion: HepPar-1 can be expressed in tumors including 8.2% of colorectal carcinoma in this study; HepPar-1 is not expressed in normal colorectal tissue.
