Meta-analysis finds HPV testing sensitivity for HSIL+ is 84.5% with urine versus 92.1% with cervical specimens.
This meta-analysis of 23 diagnostic accuracy studies compared human papillomavirus (HPV) testing for detecting high-grade squamous intraepithelial lesion or worse (HSIL+). The analysis included data from 8,332 self-collected urine samples and 8,324 physician-collected cervical samples. The study design and specific population characteristics were not reported.
The primary outcome was diagnostic sensitivity. The pooled sensitivity for HPV testing using self-collected urine specimens was 84.5%. In comparison, the pooled sensitivity for the standard method of physician-collected cervical specimens was higher at 92.1%. A subgroup analysis of studies using first-void urine collected with the Colli-Pee device showed a marginally higher sensitivity of 87.8%. Specificity, confidence intervals, and absolute numbers for these estimates were not reported.
Safety and tolerability data for the collection methods were not reported in the analysis. The authors note that self-collection, particularly using urine, is a noninvasive strategy that could help eliminate barriers to cervical cancer screening. However, key limitations include the lack of reported specificity data and detailed study population characteristics. The approximately 8-percentage-point difference in sensitivity between urine and cervical specimens suggests urine-based testing may not yet be equivalent to the current clinical standard for ruling out HSIL+.
