Investigate the Relationship Between the Presence of JCV DNA and the Immunohistochemical Expression of CK2 0, CK7, and CDX2 in Colorectal Cancer

Background: Globally, colorectal cancer (CRC) is the most common malignancy and has a high fatality rate. Early childhood the John Cunningham virus or JC virus (JCV) infection persists throughout life and has been linked through multiple routes to colorectal cancer. The expression of cytokeratins 7...

Description
Summary:Background: Globally, colorectal cancer (CRC) is the most common malignancy and has a high fatality rate. Early childhood the John Cunningham virus or JC virus (JCV) infection persists throughout life and has been linked through multiple routes to colorectal cancer. The expression of cytokeratins 7 (CK7), 20 (CK20), and CDX2 have been investigated in a variety of primary and metastatic carcinomas, and their patterns of expression may be used to determine the site of origin of metastatic carcinomas. Objectives: The aim is to assess the relationship between JCV DNA and tumor markers (CK7, CK20, and CDX2) in patients with colorectal cancer, this study was carried out. Materials and Methods: Ninety CRCs (45 of which were squamous cell carcinomas and 45 of which were adenocarcinomas) had their paraffin sections randomly chosen, extracted, and immunostained for CK7, CK20, CDX2, and for the detection of JCV DNA by real-time (PCR). Results: JCV DNA was detected in 22 (24.4%) of AD-CRC and 24 (26.7%) of SCC-CRC (P 0.004). The presence of JCV was significantly correlated with tumor stages (P 0.04) and age categories (P 0.05). Moreover, JCV presence was significantly correlated with all studied tumor markers (P < 0.05). Conclusion: JCV might play a role in the development of colorectal cancer, and CDX2, which is highly specific and sensitive as markers of colorectal origin should be helpful in the detection of intestinal adenocarcinomas.
