Abstract

An important growth factor involved in epithelial carcinogenesis is the epidermal growth factor (EGF). The present study analyze the expression pattern of EGF and its receptor (EGFR) in different stages of tumour progression in oral mucosa (normal epithelium, non-dysplastic and dysplastic leukoplakias and carcinomas). Alterations in expression pattern of EGFR was not significant in the various tissues from normal mucosa to malignancy. In all these stages EGFR positivity was confined to the immature basal or basaloid cells. EGF however showed marked alterations in expression in different stages of tumour progression in oral mucosa. Most of the malignant cells were positive for EGF antibodies while, only a few lower layers of cells were stained in normal mucosa and in dysplastic leukoplakia lesions, more number of cells expressed EGF than normal tissue. The present study thus shows the autocrine role of the EGF and EGFR and the possibility of using EGF as a marker for tumour progression in oral mucosa.
