BACKGROUND
Although urine-based testing for human papillomavirus (HPV) is being explored as a practical approach for cervical cancer screening, whether the results differ by age, race, or indicators of excess body weight or in populations exposed to HPV vaccines has not been documented by previous studies. The purpose of this study was to determine the accuracy of urinary HPV testing for the presence of cervical HPVs and high-grade cervical intraepithelial lesions (grade 2 and 3 cervical intraepithelial neoplasia [CIN]) by the aforementioned population characteristics.
METHODS
The study population consisted of 502 women diagnosed with different grades of CIN. HPV testing was performed with paired urine and cervical cell DNA with the Roche Diagnostics Linear Array test. Agreement coefficient 1 and probabilities were calculated to determine the accuracy of urinary HPV testing for the presence of cervical HPVs and CIN lesions.
RESULTS
Substantial to almost perfect agreement (0.66-0.83) was observed in the detection of any HPV genotype in urine specimens versus cervical specimens, regardless of the population characteristics. Although the positive predictive value for the detection of CIN lesions was relatively low, the negative predictive value for CIN-3 was high (≥90%) among women positive for any of the urinary or cervical high-risk human papillomavirus (HR-HPV) genotypes or HPV genotypes not included in currently available HPV vaccines.
CONCLUSIONS
The results demonstrate that urinary HPV testing provides highly satisfactory results for excluding the possibility of any cervical HPV infections, including HPV types not included in vaccines and CIN lesions associated with any HR-HPV, regardless of a woman's age, race, or excess body weight.
