g Human papillomavirus (HPV) is causally associated with anal cancer, as HPV DNA is detected in up to 90% of anal intraepithelial neoplasias and anal cancers. With the gradual increase of anal cancer rates, there is a growing need to establish reliable and clinically relevant methods to detect anal cancer precursors. In resource-limited settings, HPV DNA detection is a potentially relevant tool for anal cancer screening. Here, we evaluated the performance of the Hybribio GenoArray (GA) for genotyping HPV in anal samples, against the reference standard Roche Linear Array (LA). Anal swab samples were obtained from sexually active men who have sex with men. Following DNA extraction, each sample was genotyped using GA and LA. The overall interassay agreement, type-specific, and single and multiple genotype agreements were evaluated by kappa statistics and McNemar's 2 tests. Using GA and LA, 68% and 76% of samples were HPV DNA positive, respectively. There was substantial interassay agreements for the detection of all HPV genotypes ( ؍ 0.70, 86% agreement). Although LA was able to detect more genotypes per sample, the interassay agreement was acceptable ( ؍ 0.53, 63% agreement). GA had poorer specific detection of HPV genotypes 35, 42, and 51 ( < 0.60). In conclusion, GA and LA showed good interassay agreement for the detection of most HPV genotypes in anal samples. However, the detection of HPV DNA in up to 76% of anal samples warrants further evaluation of its clinical significance.A nal cancers are relatively rare malignancies, accounting for approximately 4% of lower gastrointestinal tract malignancies (1). Human papillomavirus (HPV) infection is causally associated with anal cancer, with HPV DNA being detected in up to 90% of anal intraepithelial neoplasias and anal cancers in both men and women (2,3). Similar to what is seen with cervical cancers, the high-risk (HR) HPV 16 is the most prevalent HPV genotype found in anal intraepithelial neoplasia and anal cancer samples (4-8). With the gradual increase of anal cancer rates (9-12), there is now a growing need for more routine anal cancer screenings and to establish reliable, reproducible, and clinically relevant methods to detect precursors to anal cancer, especially in high-risk populations like human immunodeficiency virus (HIV)-positive individuals (13). In resource-limited settings, due to the limited availability of anal cytology and high-resolution anoscopy, the detection of HPV DNA is a potentially relevant tool for anal cancer screening (14). Validated methods of HPV DNA detection and genotyping are also important for natural history studies designed to better understand the clinical relevance of these infections in the cervix and in the anal canal (15)(16)(17)(18).In this study, we evaluated the performance of Hybribio Rapid HPV GenoArray test kit (GA) (Hybribio Limited, Hong Kong) in genotyping HPV DNA extracted from anal swab samples against that of the well-established Linear Array (LA) HPV genotyping kit (Roche, USA), a widely accepted reference...
