Head-to-Head Comparison of the RNA-Based Aptima Human Papillomavirus (HPV) Assay and the DNA-Based Hybrid Capture 2 HPV Test in a Routine Screening Population of Women Aged 30 to 60 Years in Germany

ABSTRACT Testing for E6/E7 mRNA in cells infected with high-risk (HR) human papillomavirus (HPV) might improve the specificity of HPV testing for the identification of cervical precancerous lesions. Here we compared the RNA-based Aptima HPV (AHPV) assay (Hologic) and the DNA-based Hybrid Capture 2 (HC2) HPV test (Qiagen) to liquid-based cytology (LBC) for women undergoing routine cervical screening. A total of 10,040 women, 30 to 60 years of age, were invited to participate in the study, 9,451 of whom were included in the analysis. Specimens were tested centrally by LBC, the AHPV test, and the HC2 test, and women who tested positive on any test were referred for colposcopy. Genotyping was performed on all HR-HPV-positive samples. Test characteristics were calculated based on histological review. As a result, we identified 90 women with cervical intraepithelial neoplasia grade 2+ (CIN2+), including 43 women with CIN3+. Sensitivity differences between the AHPV test and the HC2 test in detecting CIN2+ ( P = 0.180) or CIN3+ ( P = 0.0625) lesions were statistically nonsignificant. Of three CIN3 cases that were missed with the AHPV test, two cases presented lesion-free cones and one had a non-HR HPV67 infection. The specificity ( P
