BACKGROUND
In recent years, high-risk human papillomavirus (hrHPV) testing for triaging atypical squamous cells of undetermined significance and cotesting with cytology have been implemented in clinical practice. However, clinical data for primary screening with human papillomavirus (HPV) testing alone are currently lacking.
METHODS
This study retrospectively reviewed the correlation of cytology, histology, and hrHPV testing through the use of a cytology laboratory quality assurance database with 130,648 Papanicolaou (Pap) tests interpreted at Houston BioReference Laboratories and Houston Methodist Hospital between March 1, 2013 and June 30, 2014. Among the 47,499 patients who had undergone cytology-HPV cotesting, 1654 underwent follow-up biopsies.
RESULTS
The sensitivities of the hrHPV and Pap tests were 80.8% and 81.2%, respectively, for detecting any type of cervicovaginal dysplasia and 91.3% and 90.9%, respectively, for high-grade cervicovaginal lesions. For biopsy-confirmed high-grade cervicovaginal lesions (cervical intraepithelial neoplasia grade 2+, adenocarcinoma in situ, or carcinoma; n = 253), the false-negative rates for hrHPV and Pap tests were 8.7% and 9.1%, respectively. The false-negative rate for cytology-hrHPV cotesting was only 1.2%.
CONCLUSIONS
In clinical practice, the hrHPV test alone is not significantly superior to the Pap test as a primary screening method for cervicovaginal lesions. The false-negative rate of the hrHPV test in detecting biopsy-confirmed high-grade cervicovaginal lesions is comparable to the rate of the Pap test. Women with cytology and hrHPV cotesting, however, have a significantly lower false-negative rate than those undergoing either test alone. Currently, cytology-HPV cotesting remains the best strategy for detecting high-grade cervicovaginal lesions. Cancer (Cancer Cytopathol) 2016. © 2016 American Cancer Society.
