Anal High-risk HPV and Liquid-based Cytology of Immunocompetent Brazilian Women with Genital High-risk HPV.

In other studies comparing groups of women with and without genital SILs, there were differences in the smoking status, number of sexual partners, and history of anal intercourse in these groups, with anal intercourse being more frequent in women with genital SILs. 5 16 17 18 These factors alone may increase the presence of anal Hr-HPV, abnormal anal cytology, and anal SILs. 3 4 10 19 The occurrence of abnormal anal cytology was more frequent in women with genital SILs than in those without SILs; however, this difference may not be significant because all women included in the genital SIL group had an ongoing histopathological diagnosis of a genital SIL, not just a past medical history of genital SILs, which limited the sample.
