    Abstract:
    OBJECTIVE: Our purpose was to determine the clinical value of human papillomavirus deoxyribonucleic acid testing with the hybrid capture test, specifically to examine whether human papillomavirus testing could identify which women with Papanicolaou smears read as atypical squamous cells of undetermined significance were most likely to have histologically confirmed cervical intraepithelial neoplasia. STUDY DESIGN: Hybrid capture testing for 14 human papillomavirus types, repeat Papanicolaou smears, and colposcopically directed biopsies were performed concurrently on 217 women referred to a student health colposcopy clinic with a previous Papanicolaou smear read as atypical squamous cells of undetermined significance. RESULTS: Human papillomavirus deoxyribonucleic acid positivity was associated with an eightfold increased likelihood of histologic confirmation of cervical intraepithelial neoplasia. The sensitivity of hybrid capture for any cervical intraepithelial neoplasia was 86% (43/50) and for grade 2 or 3 was 93% (14/15), whereas the corresponding values for the repeat Papanicolaou smear were 60% (30/50) and 73% (11/15), respectively. Moreover, high viral levels of human papillomavirus types known to be associated with cervical cancer were strongly predictive of high-grade cervical intraepithelial neoplasia. CONCLUSIONS: Testing for human papillomavirus deoxyribonucleic acid with hybrid capture appears to offer an effective means by which patients whose cervical Papanicolaou smears have been read as atypical squamous cells of undetermined significance could be triaged for colposcopy. In particular, sensitivity for high-grade cervical intraepithelial neoplasia could be maintained and specificity markedly improved by referring only those patients who had elevated levels of human papillomavirus deoxyribonucleic acid of cancer-associated viral types.
