CoCoss-Trial: Concurrent Comparison of Self-Sampling Devices for HPV-Detection

This randomised sub-study found return rates of 10.4% for Colli-Pee, 10.1% for FLOQSwabs and 7.4% for Evalyn-Brush. All devices yielded sufficient DNA with low invalid rates, but the authors noted the study was limited by low overall participation.

For decentralised testing, a study found dry vaginal self-samples using Copan FLOQSwabs stored up to two weeks at room temperature maintain DNA quality. However, first-void urine collected with the Colli-Pee device may be less sensitive for HPV detection, showing lower positivity and higher cycle threshold values, median Ct 30 versus 27 for other samples.

In 498 women living with HIV, self-collected first-void urine and vaginal samples showed 78% high-risk HPV prevalence and good genotype concordance, kappa 0.64-0.78. Participants preferred the Colli-Pee device over the Evalyn Brush, supporting decentralised, patient-centric screening feasibility.

Urine self-sampling for HPV showed non-inferior specificity to cervical samples, 85.19%, and found 96% of high-grade lesions. While acceptable, a survey of 1382 participants found 41.6% preferred conventional screening, showing the importance of offering choice in a decentralised, patient-centric programme.

First-void urine collected with the Colli-pee device detected high-grade cervical precancer with 90.3% sensitivity, substantially better than the 73.4% sensitivity of standard-pot urine, and was acceptable to colposcopy attendees. The device achieved 92% relative sensitivity compared with clinician-collected cervical samples, showing promise for decentralised HPV screening.
