Abstract

This study evaluated the immunohistochemical (IHC) expression of p16, p53 and Ki-67 in precancerous lesions and in cervical cancer (CC). Identification and review of publications assessing IHC expression in cervical intraepithelial neoplasia (CIN) and CC until February 15, 2017. Systematic review of studies in women with and without cervical lesions in order to evaluate whether there is overexpression of these biomarkers. A total of 28 publications met the criteria which included 6005 patients. The analysis showed that there is higher IHC expression of these biomarkers associated with the more severe lesions. Nineteen out of 22 evaluated studies have shown that there is a higher p16 expression in more severe lesions (CC), while in p53 expression only 4 out of the 9 studies showed a higher expression among more severe cases. Regarding the Ki-67 expression, it was observed that 9 out of 14 studies showed higher expression in more severe lesions. A complete absence of or just minimal IHC expression was observed in the normal cervical epithelium, whilst a significant increase in the expression of these biomarkers was detected according to the severity of lesions. Results suggest that these biomarkers can be considered useful tools for discriminating between the stages of the progressive cervical disease.
