Performance of a vaginal self-collection device versus clinician collected cervical samples for the detection of high-risk human papillomavirus

Abstract

ObjectiveScreening for cervical cancer requires the participation of target women. Human papillomavirus (HPV) testing can be performed on vaginal self-samples and self-sampling can improve this participation. This study aims to validate the performance of the vaginal self-sampling device (Vitroveil®) to detect high risk human papillomavirus (hrHPV) in comparison to clinician collected samples and evaluate the degree of acceptability of the Vitroveil® device. MethodsA cross-sectional observational study was carried out in a cohort of 385 participating women (median age of 44 ± 10.47 years) attending primary care centers and cervical pathology services of Granada, Spain. Two paired samples (vaginal self-sample and clinician collected cervical sample) where collected from each participant to compare the detection of HPV with the Vitro HPV Screening assay (Vitro, Granada, Spain). A questionnaire was also provided to the participants to analyze the degree of satisfaction with the device and the preference for sampling method. ResultsOverall concordance for hrHPV detection was substantial (ĸ 0.804). The prevalence of any hrHPV infection was higher in self-collected samples (30.6%) than in clinician-collected samples (24.3%). The participants found the self-sampling device easy to use and preferred self-collection as the collection method. ConclusionThe Vitroveil® self-sampling device enables safe and accruable hrHPV testing, obtaining equivalent results to those of the clinician collected samples. High acceptability of the device has been demonstrated among women in the study. Nevertheless, additional studies are necessary to verify the efficacy and reliability of the device's performance.
