title: Ki-67 labelling as a proliferation marker in pre-invasive squamous epithelial lesions of cervix.
abstract: Study was conducted to evaluate proliferation in squamous intraepithelial lesions of cervix. 36 cases of cervical biopsies were chosen including unremarkable cervix, basal cell hyperplasia, cervical intraepithelial neoplasia (CIN I, CIN II, CIN III). Ki-67 immunostaining was performed by peroxidase-antiperoxidase method. Ki-67 labelling index in basal and parabasal layers of cervix showed progressive rise with increasing grade of lesion but may not be helpful in classification of individual lesion. Also extent of staining from the basement membrane increases with increasing grade. High basal Ki-67 reactivity might be of greater biological significance than surface differentiation.
