Description:Prophylactic human papillomavirus (HPV) vaccines are recommended for prevention of HPV-associated cancers. Type-specific detection of HPV in formalin-fixed, paraffin-embedded (FFPE) tissues retrieved from diagnostic pathology laboratories is important in monitoring the impact of HPV vaccines. However, few typing assays have been validated for testing FFPE samples. Results of the Novaplex II HPV28 Detection (Novaplex) assay were compared with those from the reference assay (Linear Array with reflex Line Probe Assay) on 708 FFPE samples from cervical lesions. Novaplex showed high type-specific concordance with the reference method for HPV16/18, 9 types targeted by the Gardasil 9 vaccine, 14 high-risk types, and 21 types covered by comparison assays. The rate of inadequate samples was low in both approaches (reference, 3.4%; Novaplex, 1.7%). The proportion of discrepant types was less than 3.5% and positive concordance was greater than 75.0%. Furthermore, the type-specific positive agreement (92.0% to 98.0%), negative agreement (96.0% to 99.0%), and accuracy (97.0% to 99.0%) was high. Cohen's κ ranged from 0.86 to 0.89, indicating excellent agreement between Novaplex and reference assays. The results show that Novaplex is a suitable method for detection of HPV in FFPE tissues.
