Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are women who are eligible for cervical cancer screening and can provide informed consent.
✕Probably not a fit
Patients who have not initiated sexual intercourse, are pregnant, or have conditions that hinder cervix visualization will not benefit from this study.

What this trial studies
This study aims to improve cervical cancer screening in low- and middle-income countries by utilizing a smartphone-based artificial intelligence classifier called AVC. The AVC system records two-minute videos of the cervix during visual inspection with acetic acid (VIA) and analyzes them using an artificial neural network to provide objective classifications. This approach seeks to enhance the accuracy of VIA, which is currently dependent on the healthcare provider's experience. The collaboration involves the Gynecology and Obstetrics Department of the Geneva University Hospital and the Swiss Institute of Technology.
Why it matters
Potential benefit: If successful, this technology could significantly enhance cervical cancer screening accuracy and accessibility in resource-limited settings.
How similar studies have gone: While the use of AI in medical diagnostics is gaining traction, this specific approach to cervical cancer screening is relatively novel and has not been extensively tested in similar contexts.
