The aim of the study is to develop robust analytical protocols for first-void urine sample preparation and biomarker assays to analyze a panel of biomarkers in first-void urine for improved diagnosis of cervical (pre)cancer lesions.
In total 100 women will be included in this trial, women diagnosed with abnormal cytology results and/or high risk HPV (Human Papillomavirus) infection scheduled for a colposcopy exam. These women are asked to collect a first-void urine sample with the Colli-PeeTM device, prior to their colposcopy exam at the clinic. The collected urine samples will be used for the development and optimisation of robust analytical protocols for first-void urine sample preparation and biomarker assays.
During colposcopy, the cervix will be visually inspected, whether or not combined with a biopsy for histological confirmation. Colposcopy is a procedure to identify abnormalities by using a colposcope that gives an illuminated, magnified view of the cervical region. It often includes rinsing the cervicovaginal region with 50 ml acetic acid (5%). Here, this fluid will be collected and serve as the intermediate step between biomarkers in cervicovaginal secretions and urine.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Cases | Women (25-64 years old) with abnormal cytology results and/or (high risk) HPV infection refered for colposcopy, and hence possibly diagnosed with an (high risk) HPV infection and/or cervical (pre)cancerous lesions. No clinical evaluations/interventions will be performed by our research group. Participants have an already scheduled colposcopy exam. However, this visit is not an extra investigation that the participants should undergo when participating in the study. |
| |
| Controls | Healthy women (25-64 years old), falsely diagnosed with abnormal cytology and/or (high risk) HPV infection, but referred for colposcopy, are included as negative controls. Based on a specificity of 76.14% of the HPV type-specific PCR (polymerase chain reaction) used, an estimated 24 out of these 100 participants will be incorrectly scheduled for colposcopy and serve as the control group. No clinical evaluations/interventions will be performed by our research group. Participants have an already scheduled colposcopy exam. However, this visit is not an extra investigation that the participants should undergo when participating in the study. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| First-void urine collection | Other | One time collection of ca. 20ml of first-void urine (i.e. the initial stream of the urine void) with the Colli-PeeTM device (Novosanis). |
|
| Measure | Description | Time Frame |
|---|---|---|
| Concentration of cervical cancer biomarkers in first-void urine | To detect candidate biomarkers (originally identified in cervical cells, tissue biopsies, and cervicovaginal fluid (CVF); HPV DNA type(s), viral load (copies/cel), proteins, (m)RNA, methylated (HPV and human) DNA, immunoglobulins; in first-void urine samples from 100 women scheduled for colposcopy due to abnormal cytology. | Within 6 months after study completion |
| Measure | Description | Time Frame |
|---|---|---|
| Preference of women for self-sampling methods | Gather information about the preference of women for first-void urine sample collection compared to the currently available self-sampling methods, and a clinician collected sample (smear). | Within 6 months after study completion |
| Concentration of cervical cancer biomarkers in VagLav samples versus first-void urine |

The cohort of women involves 100 women, diagnosed with an abnormal smear and/or high risk HPV infection (cytology results already available) requested for colposcopic examination. During this colposcopic examination, cervical samples are collected and send to the pathology laboratory. In addition, these women are asked to collect a first-void urine sample with the Colli-PeeTM device and fill in a questionnaire, prior to their colposcopy exam at the clinic (UZA), during which a cervicovaginal lavage fluid sample will be collected as well.

First-void urine samples and Cervicovaginal lavage fluid (VagLav) samples
|
| Cervicovaginal lavage fluid collection | Other | During colposcopy, the cervicovaginal region is rinsed for 2 minutes with 50 ml acetic acid (5%). This fluid is not discarded like it is done usually, but the remaining lavage fluid (5% acetic acid containing cervicovaginal fluid) will be collected. |
|
|
To compare the presence of candidate biomarkers (originally identified in cervical cells, tissue biopsies, and cervicovaginal fluid (CVF); HPV DNA type(s), viral load (copies/cel), proteins, (m)RNA, methylated (HPV and human) DNA, immunoglobulins; in paired first-void urine and VagLav samples from 100 women scheduled for colposcopy due to abnormal cytology. |
