    Abstract:
    PURPOSE: In the cervix and anus, patients with atypical squamous cells of undetermined significance often do not have high-grade squamous intraepithelial lesions. In women with atypical squamous cells of undetermined significance, Hybrid-Capture II testing for oncogenic high-risk human papillomavirus is performed and those without high-risk human papillomavirus often are observed. We endeavored to determine whether Hybrid-Capture II testing would be beneficial in men who have sex with men with atypical squamous cells of undetermined significance. METHODS: We performed a retrospective chart review of men who have sex with men with atypical squamous cells of undetermined significance who had high-resolution anoscopy and Hybrid-Capture II. RESULTS: A total of 290 men were identified (mean age, 42 years), and 212 (73 percent) were HIV-negative. High-grade squamous intraepithelial lesions were found in 50 (17 percent): 23 (10 percent) who were HIV-negative and 27 (35 percent) who were HIV-positive men. High-risk human papillomavirus was found in 138 (48 percent); 91 (43 percent) of HIV-negative and 47 (60 percent) of HIV-positive men. The sensitivity, specificity, positive predictive value, and negative predictive value of atypical cells of undetermined significance cytology combined with Hybrid-Capture II were 84, 60, 30, and 95 percent, respectively. There was no significant difference between all men vs. those who were HIV-positive or HIV-negative except for the positive predictive value. CONCLUSIONS: Hybrid-Capture II testing for high-risk human papillomavirus in men who have sex with men with atypical cells of undetermined significance and referring only those with high-risk human papillomavirus reduces the number who require high-resolution anoscopy by more than half. Five percent with high-grade squamous intraepithelial lesions would be missed.
