Prognostic relevance of human papillomavirus L1 capsid protein detection within mild and moderate dysplastic lesions of the cervix uteri in combination with p16 biomarker.

摘要

OBJECTIVE: To proof the prognostic relevance of HPV L1 capsid protein detection on colposcopically-guided punch biopsies in combination with p16. STUDY DESIGN: Sections of colposcopically-guided punch biopsies from 191 consecutive cases with at least 5 years of follow-up were stained with HPV L1 capsid protein antibodies (Cytoactiv screening antibody) and a monoclonal anti-p16 antibody. Fifty sections were derived from a benign group, 91 from low-grade (cervical intraepithelial neoplasia [CIN 1]) lesions and 50 from high-grade (CIN 2 and 3) lesions. RESULTS: Overall only 16.1% of the 87 L1-negative, p16-positive CIN lesions showed remission of the lesion compared to 72.4% of the double positive cases. None of the L1/p16 double negative CIN lesions progressed. CONCLUSION: HPV L1 capsid protein detection with Cytoactiv screening antibody seems to be a promising new tool to predict the behavior of HPV-associated (p16-positive) early dysplastic lesions.
