Researchers published a study in The Lancet Obstetrics, Gynaecology & Women's Health evaluating an AI-supported cervical cancer screening strategy. The study, led by the Barcelona Institute for Global Health (ISGlobal), enrolled more than 50,000 women aged 25 to 49 across nine countries.
Why it matters
Screening coverage remains below 15% in many low- and middle-income countries, and existing methods such as acetic acid visual inspection often lack accuracy. The approach aims to support a same-day screen-triage-treat model where access to quality testing is uneven.
The PAVE study enrolled more than 50,000 women across nine countries using self-collected HPV testing for thirteen carcinogenic virus types and a deep-learning image algorithm. Whether these results translate to routine screening programs over time has not been established.
The players
Barcelona Institute for Global Health (ISGlobal)
A Barcelona-based research institute focused on reducing global disease burden through population health research, which led the study.
The details
Women who tested positive for HPV underwent cervical imaging with a portable colposcope, followed by biopsy, while a deep-learning algorithm classified findings as severe, indeterminate, or normal. The strategy integrates self-sampling, rapid testing and real-time image analysis to support screen-triage-treat care.
Timeline
2022 to 2025: Study enrolled more than 50,000 women aged 25 to 49.
2026: Study published in The Lancet Obstetrics, Gynaecology & Women's Health.
Health Landscape
The PAVE Consortium's nine-country evaluation positions this study as a test of whether automated visual evaluation can replace legacy visual inspection with acetic acid in screening programs. Effective screening is expected to remain essential for decades even as HPV vaccination expands globally.
For women in regions with limited access to HPV testing, a same-day screening approach could mean results and follow-up care in a single visit. Self-collected sampling may also reduce the need for clinical visits to begin screening.
The takeaway
Screening programs that combine self-collected HPV testing with rapid image analysis may reduce reliance on less accurate visual methods. Women can ask their health providers which screening options are available in their area.
