Objective: The objective of the study was to determine the sensitivity and specificity of the APTIMA human papillomavirus (AHPV) assay for high-grade cervical intraepithelial neoplasia (CIN) in women 21 years old and older with atypical squamous cells of undetermined significance (ASC-US) cytology.
Study design: Women 21 years old and older with ASC-US cytology had colposcopy/biopsy and molecular human papillomavirus testing. Performance of the AHPV and Hybrid Capture 2 assays was compared with a clinical diagnosis of CIN grade 2, CIN grade 3, or adenocarcinoma in situ (CIN2 or greater).
Results: Of 939 evaluable subjects, CIN2 or greater and CIN3 or greater prevalence was 9.7% and 4.4%, respectively. AHPV sensitivity and specificity was 86.8% and 62.9% for CIN2 or greater detection and 90.2% and 60.2% for CIN3 or greater, respectively. AHPV had a similar sensitivity to Hybrid Capture 2 but a significantly higher specificity (62.9% vs 55.8%, P < .001) for CIN2 or greater detection.
Conclusion: Among women with ASC-US cytology, detection of high-risk human papillomavirus E6/E7 oncogenic messenger ribonucleic acid is an effective triage method for colposcopy referral.
