Abstract

β-catenin plays an important role in the maintenance of cell adhesion and is a key component of the Wnt signaling pathway. However, little is known about its prognostic significance or its role in tumor progression in tongue squamous cell carcinoma (SCC). This study conducted an immunohistochemical analysis of the expression of β-catenin. Moreover, its possible correlation with clinical parameters and with the expression of the functionally related molecular markers cyclin D1 and p53 was evaluated in 50 cases of tongue SCC and 10 cases of normal tongue epithelium. The ki-67 labeling index (LI) was also examined to evaluate cellular proliferation. Our results showed a higher frequency of abnormal β-catenin expression, positive cyclin D1 and p53 expression, and a significantly higher ki-67 LI in the tongue SCC samples compared with normal tongue epithelium (P<0.05). Abnormal β-catenin and a higher ki-67 expression was significantly associated with moderately or poorly differentiated carcinoma (P<0.05). Cyclin D1-positive immunostaining showed a statistically significant association with lymph node metastasis (P<0.05). Furthermore, the abnormal expression of β-catenin significantly correlated with a higher ki-67 LI and p53 expression (P<0.05); however, there was no correlation with cyclin D1 expression (P>0.05). Taken together, our results suggest that abnormal β-catenin expression is related to the impaired cellular differentiation and proliferation involved in tumor progression in tongue SCC.
