Prognostic value of E-cadherin expression in 413 gastric carcinomas
1996
E-cadherin is a Ca(2+)-dependent intercellular adhesion molecule known to exert an invasion-suppressor function. In the present study, E-cadherin expression was immunohistochemically investigated in a retrospective series of 413 RO-resected gastric carcinomas using the monoclonal antibody (MAb) 5H9. Of these cases, 108 tumors revealed a preserved E-cadherin expression similar to that of normal gastric mucosa. In 95 tumors, E-cadherin expression was moderately reduced and in 86 tumors highly reduced. In 124 tumors, no or only a very weak dotted expression could be detected. There was a significant correlation between the degree of E-cadherin expression and the grade of tumor differentiation,…
Different patterns of β-catenin expression in gastric carcinomas: relationship with clinicopathological parameters and prognostic outcome
2001
Different patterns of β-catenin expression in gastric carcinomas: relationship with clinicopathological parameters and prognostic outcome Aims: The cadherin–catenin complex is known to play a critical role in maintenance of cell adhesion. Additionally β-catenin (β-ct) can also take part in signal transduction and nuclear β-ct expression could be correlated with poor prognosis in several malignancies. Since, in gastric cancer, this role of β-ct is still uncertain, we investigated the expression pattern of β-ct as well as the possible prognostic role. Methods and results: β-catenin expression was immunohistochemically investigated in a retrospective series of 401 R0-resected gastric carcinoma…
