Introduction: Immunohistochemistry (IHC) for p16INK4A (p16) is a reliable surrogate test for the presence of a high-risk, potentially transformative human papillomavirus (HPV) infection in precursor and malignant lesions of the cervix. The purpose of this study was to evaluate changes in cervical cells caused by persistent HPV infection, by IHC (p16 protein) by comparison with HPV genotyping. Patients, Materials and Methods: The study included female patients aged between 26 and 57 years who presented to a public hospital, with complaints related to the genital area, namely vaginal bleeding and dyspareunia. After selecting the patients, samples were subjected to cytological testing and IHC for p16 and for the determination of HPV types. Results: The relationship between HPV status and p16 status was statistically significant (p=0.0001), of the 41 patients, 53.7% were HPV positive, respectively 56.1% were p16 positive, the agreement relationship between the two indicators was very high (weighted kappa: 0.951). The clinical performance of CINtec PLUS triage for p16 shows a high positive predictive value (PPV) and a high negative predictive value (NPV) of 95.7% and 100%, respectively, as regards HPV. Conclusions: The p16 marker (CINtec PLUS) can be used as a prognostic biomarker and provides clinical usefulness through increased sensitivity (Se) and specificity (Sp) in the triage of women at risk of developing precancerous lesions, compared to cytology that is based on morphology, but has a rather low Se and high Sp, while HPV testing is very sensitive but slightly more specific.
