Brief summary
The European VALHUDES study is a Clinical Performance /Diagnostic Test Accuracy Study that aims to evaluate whether HPV testing with new assays performed on self-samples, collected by means of a vaginal and a urine collection device is as accurate to detect cervical pre-cancer as on cliniciantaken cervical samples.
Detailed description
Women accessing the Colposcopy Centres for a colposcopy examination and fulfilling the selection criteria will be asked, after written informed consent, to self-collect a first-void urine (with the Colli-Pee device) and a vaginal sample (with the FLOQSwab device), prior to undergoing colposcopy. Just before colposcopic examination, a clinician will also take a cervical sample (with a Cervex-Brush using the same procedure normally adopted for cervical cytology and/or HPV testing. During colposcopy, a colposcopy-targeted biopsy may be taken if appropriate. When according to colposcopy and biopsy results, an excisional treatment of a cervical precancer lesion is needed, the histology of the excised tissue will complete the end point of the study. The colposcopy and histological findings will be used as the gold standard if biopsies are taken. In case of normal satisfactory colposcopic findings without biopsy taking, colposcopy will provide the study outcome. Three new PCR-based HPV 'in vitro diagnostic devices' (Papilloplex, HPV Oncopredict RNA, HPV Oncopredict DNA) developed as part of the SME Instrument Project 'HPV OncoPredict (GA-806551)' will be assessed.

| Relative accuracy self-collected vaginal vs clinician-collected samples | One day, with possible extension if excision biopsy is planned based on the coloposcopy/histology outcome of tissue specimens collected at the enrolment visit. | Relative sensitivity and specificity of each hrHPV DNA assay for detection of cervical intraepithelial neoplasia of grade II or worse (CIN2+) on self-collected vaginal vs on clinician-collected samples. |

| Questionnaire for the acceptance of self-collection | One day, at the day of colposcopy | Women's acceptance and preference regarding urine collection, vaginal self-sampling or collection by a clinician will be assessed through a questionnaire. |
| Correlation internal control gene signals between different sample types | One day, with possible extension if excision biopsy is planned based on the coloposcopy/histology outcome of tissue specimens collected at the enrolment visit. | Correlation of signals for the human internal control gene between urine, vaginal and clinician-collected samples. |
