Anal prevalence of HPV in women with pre-malignant lesion or cancer in the cervix and anal canal simultaneously: cross-sectional study.

Objective: To determine the prevalence of anal HPV genotypes and associated factors in women with pre-malignant lesion or cancer in the cervix and anal canal.

Methods: A prospective, cross-sectional study analyzed DNA samples taken from women with cervical pre-malignant lesions or cancer to identify anal HPV by polymerase chain reaction (PCR). The prevalence of high-risk HPV (HR-HPV) in women with intraepithelial neoplasia and anal cancer was calculated; sociodemographic and clinical risk factors were identified using multivariate analysis.
