Background and objective: Colorectal cancer is a heterogeneous malignancy characterized by a wide range of genetic and epigenetic alterations. Clusterin is a heterodimeric glycoprotein widely expressed in a variety of tissues and secreted in many body fluids. Increased clusterin expression has been reported in the normal colonic mucosa, benign polyps, and colorectal carcinoma. This study aimed to detect the frequency of the clusterin immunoexpression in colorectal carcinoma and determine its association with some clinicopathological parameters.

Conclusion: Our study indicated that clusterin is overexpressed in some colorectal carcinomas and is significantly associated with histological type and grade. These results suggest that clusterin may play a role in colorectal carcinogenesis. Further studies are required to understand the possible mechanism of clusterin association with carcinogenesis and cancer progression.
