Abstract

This study aimed to investigate the correlation between ${\beta}$-catenin immunoexpression and histopathological grades of lower lip squamous cell carcinoma (LSCC). $\beta$-Catenin abnormal expression was found in 29% of the squamous cells of well differentiated LSCC, 63% of moderately differentiated and 86% of poorly differentiated, and therefor was significantly associated with histological grade (p=0.000). Nuclear $\beta$-catenin expression appeared in 5% of the cells and was also correlated with the histological grades (p=0.000). In 14.7% of the cells it was localized in the cytoplasm, again correlating with histology (p=0.002). According to this study the expression of $\beta$-catenin is an independent prognostic factor for histological grade and to the tumor differentiation. This appears to reflect a structural association and the role of $\beta$-catenin in tumor progression.
