Thirty laryngeal carcinomas were studied immunohistochemically in order to evaluate whether the expression and different distribution of adhesion molecules influence the clinical features and progression of the tumors. On the basis of clinical and pathological variables, two different groups were established: one with good and the other with poor prognosis. The patients were included in one of the two groups on the basis of prognostic factors previously studied by multivariate analysis (the validity of this choice was confirmed by the NED survival curves of the two groups). Different integrins, type I and V laminin and type IV collagen were evaluated by means of monoclonal antibodies in the tumoral specimens and in normal mucosa. Univariate statistical analysis was performed to evaluate differences between the two groups. The degree of expression and pattern of distribution were different in tumor compared with normal mucosa and significant differences were found between the good- and worst-prognosis tumors.
