Most cervical cancers are caused by 15 high-risk (HR) and three probable high-risk (pHR) oncogenic types of human papillomavirus (HPV). However, current commercial HR HPV screening test products do not include pHR HPV genotypes. Recently, PapilloScreen has been developed to detect the 15 HR and three pHR HPV types. In this study, we evaluated the concordance levels and clinical performance of Hybrid Capture 2 (HC2), PapilloScreen, and a PCR sequencing assay in detecting HR and pHR HPV. The PapilloScreen (96.8 %) and PCR sequencing assay (96.8 %) demonstrated higher sensitivity than HC2 (80.7 %) for detecting HR and pHR HPV. The three assays showed similar specificities and positive or negative predictive values. The concordance levels were 86.5 % (κ = 0.68) and 86.5 % (κ = 0.67) between HC2 and PapilloScreen and between HC2 and PCR sequencing, respectively. A near-perfect concordance was observed between PapilloScreen and PCR sequencing (97.8 %, κ = 0.95). Overall, the agreement between the three assays suggests that the results obtained by the HC2 assay are more often discordant (12.6 %) than the PCR-based tests. In conclusion, PapilloScreen is highly sensitive for detecting high-grade CIN or cervical cancer. The PapilloScreen assay should be considered an accurate and sensitive method for detecting HR and pHR HPV infections and an epidemiological tool for prevalence studies as well as early diagnosis and intervention in HR and pHR HPV infections.
