Comparison of clinical performances among Roche Cobas HPV, RFMP HPV PapilloTyper and Hybrid Capture 2 assays for detection of high-risk types of human papillomavirus.

The cervical cancer screening guidelines suggest that early detection of HPV16 and HPV18 is helpful for identifying women with cervical intraepithelial neoplasia (CIN) grade two or higher. We comparatively evaluated three HPV DNA assays, Roche Cobas HPV, RFMP HPV PapilloTyper, and Hybrid Capture 2 (HC2). A total of 861 cervical swab samples from women over 30 years of age were classified into two groups, that is, high grade squamous intraepithelial lesion (HSIL) and non-HSIL, according to cervical cytology results and analyzed by three assays. The results of direct sequencing or Linear array HPV genotyping test were considered true when the three assays presented discrepancies. The concordance rates between Roche Cobas HPV versus RFMP HPV PapilloTyper, RFMP HPV PapilloTyper versus HC2, and Roche Cobas versus HC2 were 94.5%, 94.3%, and 95.9%, respectively. For detection of HPV16 and HPV18, Roche Cobas HPV showed the concordance rates of 98.3% (κ = 0.73) and 99.4% (κ = 0.40) with the confirmation tests, respectively; and RFMP HPV PapilloTyper showed the concordance rates of 99.5% (κ = 0.92) and 100.0% (κ = 1.00), respectively. In conclusion, Roche Cobas HPV, RFMP HPV PapilloTyper, and HC2 showed high agreement rates. Roche Cobas HPV and RFMP HPV PapilloTyper are particularly useful, since both provide HPV specific genotypes, HPV16 and HPV18.
