Abstract

Despite the improvement in the diagnostic and the therapeutic modalities, colorectal cancer (CRC) morbidity and mortality remain high in both the developed and the developing countries. So, we are in a need to recognize new efficient diagnostic and prognostic biomarkers of CRC. That may help in providing individualized targeted therapy for this lethal malignancy. In this study, we investigated the expression and the prognostic significance of CD133 and ezrin mRNA and protein by quantitative RT-PCR and immunohistochemical analysis in primary CRC cases and the surrounding normal colonic mucosa. The correlations between the expression of both markers and clinicopathological parameters were performed. Compared to control, the expression of CD133 and ezrin mRNA and protein in CRC were significantly up-regulated (P < 0.05). In addition, a strong positive correlation between both markers was found (r = 0.867, P < 0.001). Moreover, elevated levels of both markers were significantly associated with the stage, lymph node involvement, distant metastasis, and recurrence at both mRNA and protein levels (P < 0.05). In conclusion, there is a clinical significance of CD133 and ezrin as potential biomarkers for predicting CRC patients of aggressive behavior and poor prognosis.
