Summary
Immunohistochemical staining of epidermal growth factor receptor (EGF-R) with a monoclonal antibody was performed in 43 biopsies of cervical tissue. The distribution of the receptors in normal cervical tissue differs from that of cervical intraepithelial neoplasia (CIN) and squamous cell carcinoma of the cervix. Whereas the staining reaction in normal squamous epithelium was confined to the basal and deep parabasal cell layer, in all cervical intraepithelial neoplasias, with or without human papilloma virus association, a homogeneous EGF-R staining reaction could be observed throughout the entire lesion. This means that the dysplasia cells of a CIN I-III, like the tumor cells of a squamous cell carcinoma, have a raised EGF-R content, which in the normal squamous epithelium is usually only found in the basal and deep parabasal cells that are capable of dividing. No EGF-R staining reaction could be detected in the higher, differentiated cell layers of the normal squamous epithelium of the cervix.
