Abstract

Tumour cells are characterised by uncontrolled growth due to alterations in the genes that play a key role in cell repair systems and apoptosis: pro-mitotic oncogenes such as cyclin D1, and tumour suppressor genes such as p27. Recent studies have demonstrated that these genes are involved in different epithelial neoplasms and that their expression is generally associated with prognosis. The aim of this immunohistochemical study was to analyse the clinical relevance of cyclin Dl/p27 co-expression in a homogeneous series of 132 laryngeal squamous cell carcinomas. Multivariate analysis showed that cyclin D1 and p27 were the only statistically significant predictors of disease-free and overall survival. In relation to the simultaneous expression of p27 protein and cyclin D1, the patients with a cyclin D1+/p27-phenotype had the poorest disease-free and overall survival rates. On the basis of these immunohistochemical results, it was possible to select a subgroup of patients with a high risk of recurrence and poor prognosis to undergo more extended surgical treatment and/or combination antitumoral therapeutic procedures.
