The aim of this study was to evaluate the prevalence of anal high-grade squamous intraepithelial lesions\/anal intraepithelial neoplasia (HSIL\/AIN), determine whether the anatomical distribution of genital HPV-associated disease provides clinically relevant information for risk stratification, and to assess the diagnostic performance of different screening strategies in this high-risk population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A total of 100 immunosuppressed women undergoing ASCC screening were included.

The proportion of women with HSIL\/AIN differed according to the anatomical distribution of HPV-related genital lesions. Women with vulvar HSIL, either as isolated disease (52.6%) or as part of multizone HSIL (64.3%), showed the highest proportion of detected HSIL\/AIN, whereas HSIL\/AIN was detected less frequently among women with HPV infection without genital HSIL (22.2%) (p=0.037 and p=0.007, respectively). Anal HPV testing alone showed high sensitivity (97.0%; 95% CI: 84.2-99.9) and negative predictive value (95.7%; 95% CI: 78.1-99.9), whereas combined strategies slightly increased sensitivity at the expense of lower specificity and higher referral rates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>In conclusion, the anatomical distribution of HPV-associated genital disease appears to provide clinically relevant risk stratification. Women with vulvar HSIL represent a priority subgroup for ASCC screening. Anal HPV testing alone showed high sensitivity and NPV. These findings suggest that anal HPV testing may represent a useful primary screening approach in this population.<\/jats:p>\n
