Abstract

Background: Several studies indicate that chemokines play important roles in colorectal mucosal immunity.
The chemokine CXCL5 which is expressed by epithelial cells within colorectal mucosa is a promoter of cell proliferation,
migration and invasion, is a novel serum prognostic marker in patients with colorectal cancer. The purpose of this study
was to investigate whether serum and tissue CXCL5 levels is altered in colorectal carcinomas (CRC) compared to colonic
adenoma and normal mucosa.It also aimed to compare colon adenoma and colorectal cancer for blood CXCL5 and
CEA levels, their sensitivity, and specificity. Methods: CXCL5 expression was assessed with immunohistochemistry
staining in biopsy samples taken during colonoscopy in 22 colonic adenomas, 23 colorectal carcinomas and 23 normal
colonic tissue samples. Also all patients’ serum CXCL5 and CEA levels were measured. This stduy was prospective
observational study. Results: The number of cases who were stained positive with immunohistochemistry was found to
be higher in the group with CRC. When compared with the other groups, both levels of serum CXCL5 and CEA were
significantly high in the group CRC. Sensitivity and specificity of serum CXCL5 were found to be low as a result of
the ROC analysis. Conclusion: Although the level of CXCL5 is high in CRC, its level in serum is not significant
enough to support the early diagnosis of the disease.
