Proliferative activity of the epithelium in squamous epithelial lesions of the cervix

As a criterion for precancerous changes in the stratified squamous epithelium of the cervix, its proliferative activity, studied using monoclonal antibodies PC-10 to the antigen of proliferating cell nuclei (PCNA), is considered. The results of the studies showed that patients with a low degree of squamous intraepithelial lesion are characterized by weak proliferative activity, and for patients with a high degree of lesion it is moderate and pronounced. An increase in proliferative activity is a prognostic factor that determines long-term persistence and the likely progression of the lesion.
