Expresión inmunohistoquímica de la proteína p53 y su valor pronóstico en el cáncer de laringe

We carried out an immunohistochemical study of p53 (DO7) expression in a series of 195 patients with laryngeal squamous cell carcinoma, treated and followed at the Department of Otolaryngology Virgen de la Salud Hospital (Toledo, Spain). In the cases with lymph node metastasis we also studied p53 expression at this site. We have investigated the value of p53 expression as a prognostic factor (tumor recurrence, deads due tu cancer and survival) and we have evaluated the relationship between p53 expression and other clinicopathologic characteristics.
