title: Expression of ER-D5 and EGFr in laryngeal carcinoma and pre-malignant epithelium.
abstract: The expression of estrogen receptors was biochemically assessed in a series of 46 cases of consecutive laryngeal carcinomas. ER-D5 and EGFr were also immunohistochemically detected in 44 and 46 cases respectively. There was no correlation between the expression of these molecules and the typical anatomo-clinical prognostic parameters of laryngeal tumors. The concomitant expression of estrogen receptors, ER-D5 and EGFr was also investigated in normal, hyperplastic and dysplastic epithelium. An increasing expression of ER-D5 and EGFr from normal to hyperplastic and dysplastic epithelium was noted. These data suggest a possible role of hormone receptors in the laryngeal carcinogenesis.
