Expression of p16/Ki-67 in ASC-US/LSIL or Normal Cytology with Presence of Oncogenic HPV DNA.

Aim: To determine if positive dual staining of p16/Ki-67 in cytology samples from women with atypical squamous cells of undetermined significance (ASC-US), low-grade squamous intraepithelial lesion (LSIL) or normal cytological reports with presence of high-risk human papillomavirus (HPV), helps in predicting the risk of developing high-grade cervical lesions during one-year of follow-up after a normal initial colposcopy.

Materials And Methods: One-hundred and sixty women with ASC-US, LSIL or otherwise normal cytology, but with the presence of high-risk HPV, were referred to the colposcopy Unit of our Hospital. Cytology and HPV testing were repeated and dual staining of p16/Ki-67 performed on a new cytological specimen, and subsequently patients were colposcopically assessed and prospectively followed-up for one year, after which the colposcopy was repeated.
