HPV-associated anal lesions

Tuesday 30 November 2010

The classification of anal intraepithelial neoplasia (AIN) in mucosal biopsies is subject to considerable interobserver variability. Ki-67 and p16/CDKN2A immunostains aid detection of dysplasia in biopsy samples from the uterine cervix.

Ki-67 labeling detects anal HPV-related changes with a high degree of sensitivity and specificity, whereas increased p16/CDKN2A staining is strongly associated with high-grade squamous neoplasia. A combination of these markers may aid interpretation of anal mucosal biopsy samples. (20871219)
