Abstract

Background and Objectives: Because of squamous cell carcinoma of the head and neck undergoes a generally poor hospital course, the prognostic significance of the squamous cell carcinomas in head and neck have been evaluated to identify those features associated with aggressive biologic behavior according to the immunologic and histopathologic characteristics. Materials and Method: To assess the significance of EGFR, c-erbB-2, p21 and p53 protein in head and neck tumors and their correlation with prognostic factors, samples from 74 patients with squamous cell carcinomas of larynx, pharynx, and oral cavity were studied immunohistochemically. Results: EGFR, c-erbB-2, p21, and p53 protein were expressed 94.6%, 24.3%, 85.1%, and 55.4% in 74 cases of head and neck squamous cell carcinoma, respectively. The positive expression of EGFR was associated significantly with clinical stage and the negative expressions of p21 was associated significantly with histopathologic differentiation. There were no significant relationships between the reactivity of EGFR, c-erbB-2, p21, and p53 protein. Conclusion: The expression of EGFR, c-erbB-2, p21 and p53 protein could be related to oncogenesis, and the expression of p21 and EGFR protein can be used as a prognosticator in head and neck squamous cell carcinoma under certain limitations, but c-erbB-2 and p53 protein expression alone is not enough for evaluating prognosis of the carcinoma.
