Nuclear β-catenin expression appearedin 5% of the cells and was also correlated with the histological grades (p=0.000). In 14.7% of the cells it waslocalized in the cytoplasm, again correlating with histology (p=0.002). According to this study the expressionof β-catenin is an independent prognostic factor for histological grade and to the tumor differentiation. Thisappears to reflect a structural association and the role of β-catenin in tumor progression. %U https://journal.waocp.org/article_31233_9e11d0e33efb2806c0f19dfcf34a3c3f.pdf
