ABSTRACT
<p><b>OBJECTIVE</b>To investigate the expressions of WWOX and CD133 in colorectal cancer (CRC) and their relationship with the clinicopathologic characteristics of CRC.</p><p><b>METHODS</b>The expressions of WWOX and CD133 proteins were examined by immunohistochemistry in 174 specimens of CRC tissues and 80 normal colorectal mucosa tissues.</p><p><b>RESULTS</b>The positivity rates of WWOX and CD133 proteins were 41.4% and 53.4% in CRC tissues, respectively, significantly different from the rates in normal colorectal mucosa tissues (87.5% and 5.0%, respectively; P<0.05). WWOX and CD133 protein expressions were signi- ficantly correlated with the histological grades of the tumors, depth of invasion, lymph node metastasis, and Duke's stages (P<0.05). Spearman analysis showed a negative relationship between the WWOX expression and CD133 expression (P<0.05). Kaplan-Meier survival analysis showed that the overall survival time of CRC patients with a positive expression of WWOX was longer than that of patients with a negative expression of WWOX; the overall survival time of patients with a positive expression of CD133 was shorter than that of the negative patients (P<0.05). COX regression analysis identified positive expressions of WWOX and CD133 protein and Duke's stage as the independent prognostic factors of CRC.</p><p><b>CONCLUSION</b>Abnormal expressions of WWOX and CD133 might be involved in the initiation, development, invasion, and metastasis of CRC. A combined detection of WWOX and CD133 can help in predicting the progression and prognosis of CRC.</p>
