Epidermal growth factor receptor (EGF-R) and the oncogene product of c
-erbB-2 have been shown to be expressed in human tumors and in some ca
ses relate to clinical outcome. This study investigates the correlatio
n between the presence of these receptor proteins and various histolog
ical grades of cervical tissues. Imunocytochemical analysis of benign,
premalignant and malignant cervical tissues showed a highly significa
nt correlation between the expression of the two proteins and the hist
ological grade of the lesions. Moreover, the overall frequency of coex
pression of these proteins was similar. This study suggests that these
proteins may be involved in cellular proliferation and have a signifi
cant role in the progression of cervical cancer.
