Abstract BACKGROUND:People living with HIV have high rates of anal human papillomavirus infection and anal precancer/cancer. OBJECTIVE:This study aims to1) determine human papillomavirus subtype distribution among people living with HIV with anal high-grade squamous intraepithelial lesions; 2) compare the clinicopathological characteristics of patients with anal high-grade squamous intraepithelial lesions by human papillomavirus 16 status; and 3) investigate high-risk human papillomavirus negative anal high-grade squamous intraepithelial lesion cases. DESIGN:In this retrospective study, 700 people living with HIV who have biopsy-proven anal high-grade squamous intraepithelial lesions were reviewed for demographics, cytological diagnoses, and human papillomavirus testing results for human papillomavirus 16, 18, and 12 other high-risk types. For human papillomavirus-negative subjects, corresponding biopsies were genotyped by using real-time polymerase chain reaction. SETTINGS:This study was conducted in a large urban HIV clinic system and major referral center for anal cancer screening. PATIENTS:Median age was 46 years (range, 20–76). Ninety-one percent of the patients were men who have sex with men. MAIN OUTCOME MEASURES:The primary outcome measure was the association between demographic variables and human papillomavirus 16 status. RESULTS:Anal cytology was unsatisfactory (5%), benign (13%), atypical squamous cells of undetermined significance (35%), low-grade squamous intraepithelial lesion (36%), and high-grade squamous intraepithelial lesions (11%). Human papillomavirus cotesting results were negative (n = 38, 5%), human papillomavirus 16 (n = 303, 43%), human papillomavirus 18 (n = 78, 11%), or exclusively non-16/18 types (n = 281, 40%). Human papillomavirus 16 positivity was associated with ≥3 high-grade lesions and ≥ low-grade squamous intraepithelial lesion cytology (p < 0.001). Age, race/ethnicity, sex, smoking, CD4+ T-cell count, and HIV viral load did not differ by status of human papillomavirus 16 (p > 0.05). For human papillomavirus-negative cases, human papillomavirus genotyping of biopsies was positive for high-risk (n = 14, 36%) or possibly carcinogenic types (n = 12, 32%), or negative (n = 12, 32%). LIMITATIONS:This was a retrospective data analysis, and it pooled the results for 12 high-risk human papillomavirus types rather than individual types. CONCLUSIONS:Nearly all people living with HIV and anal high-grade squamous intraepithelial lesions test positive for high-risk human papillomavirus on anal swabs; negative results may be due to sampling error, L1-based polymerase chain reaction assay, or human papillomavirus types not captured by standard clinical assays. Patients who have human papillomavirus 16-positive anal high-grade squamous intraepithelial lesions are indistinguishable from others based on demographic and clinical characteristics, underscoring the potential role of human papillomavirus testing for anal cancer screening.
