Abstract:

Conclusion. Contrary to most reports, our study shows that the expression of cyclin D1 is not an independent prognostic factor in patients with laryngeal cancer (LC). No correlation between cyclin D1 expression and survival rates in LC was found in a multivariate analysis. Objectives. The aim of this study was to determine the possible relevance of the expression of cyclin D1 protein in LC as prognostic criteria and to analyse correlation of the expression with clinicopathological features and survival rates. Materials and methods. Immunohistochemistry staining was used to detect the expression of cyclin D1 in 130 samples of laryngeal cancer and in 22 specimens of laryngeal nodules. Results. Cyclin D1 expression was found in 52 (40%) LC samples and in 3 (13.6%) samples of laryngeal nodules. There was no significant correlation between cyclin D1 expression and clinicopathological features of LC. A multivariate analysis of survival confirmed that cyclin D1 expression was not an independent prognostic factor in LC.
