Antibodies to the Human Papillomavirus 16 and 18 E7 Proteins: A Possible Diagnostic Marker for Cervical Cancer
Abstract
Human papillomavirus (HPV) types 16 and 18 belong to a heterogeneous group of epitheliotropic viruses which induce benign proliferations of the skin or mucosa (for review, see de Villiers 1989). During the past few years it became evident that they are associated with malignant tumors of the anogenital tract, particularly of the uterine cervix (for review, see zur Hausen 1989). Besides the demonstration of the transforming activity of the early viral genes E6 and E7 in vitro, the strongest evidence for a causative role of HPV 16 and HPV 18 in tumor development arose from the frequent detection of their genomes in tumor biopsies as well as in cell lines derived therefrom. After the tumorigenic properties of HPV 16 and 18 had become apparent, it was assumed that detection of the virus in healthy individuals could be of diagnostic value for determining the risk of developing cancer of the uterine cervix. Subsequent studies, however, demonstrated that the viruses quite frequently persist in clinically normal cervical epithelium, and it is not yet clear how frequently a latent infection may lead to a clinically overt lesion and finally to a malignant tumor.
