p16^INK4a is superior to high‐risk human papillomavirus testing in cervical cytology for the prediction of underlying high‐grade dysplasia

Abstract

: This p16(INK4a) immunocytochemical assay has superior specificity but similar sensitivity to HR-HPV testing to predict underlying high-grade dysplastic lesions in patients who are referred for colposcopy. The determination of the overall performance characteristics of p16(INK4a) immunocytochemistry, as an independent test or in combination with HPV testing in low-risk screening populations, however, will require subsequent large-scale prospective clinical trials.
