| Popis: | CD44 is a cell surface receptor implicated in cancer progression and metastases. Malignant tumors may show a loss of CD44 splice control mechanisms. We investigated the role of CD44 splice variant expression in ovarian tumors and metastases, and its association with survival.We tested CD44 expression in 142 cases of epithelial carcinoma of the ovary and 265 metastatic sites by immunohistochemistry.Survival analysis showed that the expression of CD44s, CD44-v4, -v5, -v6, -v9, and -v10 are significant predictors for survival in univariate analysis. After stage, the expression of CD44-v10 in metastases was the strongest predictor of decreased survival in multivariate analysis (p = 0.0009). Conversely, CD44-v10 expression in the primary tumor was an independent predictor of improved survival in multivariate analysis (p = 0.0002). The expression of CD44s in the tumor/stroma interface of the primary tumor was associated with improved survival (p0.0001).CD44 variant expression is a molecular prognostic maker for epithelial ovarian carcinomas. CD44-v10 expression is an independent prognostic indicator and the site of expression determines a positive or negative influence in survival. Our results also indicate that CD44 may be involved in important tumor/stroma interactions. |
