Accuracy of urinary human papillomavirus testing for the presence of cervical human papillomaviruses and higher grades of cervical intraepithelial neoplasia.

ABSTRACT: 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.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.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.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.

Project description:A substantial effect of human papillomavirus (HPV) vaccines on reducing HPV-related cervical disease is essential before modifying clinical practice guidelines in partially vaccinated populations.To determine the population-based cervical intraepithelial neoplasia (CIN) trends when adjusting for changes in cervical screening practices that overlapped with HPV vaccination implementation.The New Mexico HPV Pap Registry, which captures population-based estimates of both cervical screening prevalence and CIN, was used to compute CIN trends from January 1, 2007, to December 31, 2014. Under New Mexico Administrative Code, the New Mexico HPV Pap Registry, a statewide public health surveillance program, receives mandatory reporting of all cervical screening (cytologic and HPV testing) and any cervical, vulvar, and vaginal histopathological findings for all women residing in New Mexico irrespective of outcome.Prespecified outcome measures included low-grade CIN (grade 1 [CIN1]) and high-grade CIN (grade 2 [CIN2] and grade 3 [CIN3]).From 2007 to 2014, a total of 13?520 CIN1, 4296 CIN2, and 2823 CIN3 lesions were diagnosed among female individuals 15 to 29 years old. After adjustment for changes in cervical screening across the period, reductions in the CIN incidence per 100?000 women screened were significant for all grades of CIN among female individuals 15 to 19 years old, dropping from 3468.3 to 1590.6 for CIN1 (annual percentage change [APC], -9.0; 95% CI, -12.0 to -5.8; P?<?.001), from 896.4 to 414.9 for CIN2 (APC, -10.5; 95% CI, -18.8 to -1.2; P?=?.03), and from 240.2 to 0 for CIN3 (APC, -41.3; 95% CI, -65.7 to 0.3; P?=?.05). Reductions in the CIN2 incidence were also significant for women 20 to 24 years old, dropping from 1027.7 to 627.1 (APC, -6.3; 95% CI, -10.9 to -1.4; P?=?.02).Population-level decreases in CIN among cohorts partially vaccinated for HPV may be considered when clinical practice guidelines for cervical cancer screening are reassessed. Evidence is rapidly growing to suggest that further increases in raising the age to start screening are imminent, one step toward integrating screening and vaccination.
