NContext.—Cervical cancer screening in women younger than 30 years relies on cervical cytology because of the poor performance of human papillomavirus (HPV) DNA testing in this age group. Objectives.—To determine the performance of in-cell HPV E6, E7 mRNA quantification (HPV OncoTect) for the
detection of high-grade cervical intraepithelial neoplasia in women younger than 30 years. Design.—We analyzed 3133 cytology specimens from a screening population of women aged 19–75 years investigate HPV OncoTect as a triage/secondary screening test for atypical squamous cells of undetermined significance
(ASCUS) and low-grade squamous intraepithelial lesion (LSIL) cytology in women younger than 30 years. Test results were compared to histology in 246 cases. Results.—The sensitivity of E6, E7 mRNA was 89% for CIN 2+ and 100% for CIN 3+ lesions in women 30 years and older. In women younger than 30 years, the sensitivity of E6, E7 mRNA for CIN 2+ lesions was 88% for CIN 2+ and 92% for CIN 3+ lesions. Abnormal cytology ($ASCUS) exhibited a sensitivity of 89% for CIN 2+ and 100% for CIN 3+ in women 30 years and older and 96% sensitivity for CIN 2+ and 93% sensitivity for CIN 3+ in women younger than 30. The specificity of E6, E7 mRNA was .80% for CIN 2+ and CIN 3+ in both groups of women compared to a specificity of abnormal cytology of ,10% for CIN 2+ and CIN 3+ in both groups. Conclusions.—HPV OncoTect demonstrates a performance that would be effective for ASCUS/LSIL triage in women including those younger than 30 years.
