Heat probe zaps HPV: danish trial tests new ablation approach
NCT ID NCT07376031
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a heated probe applied to the cervix (thermal ablation) can help clear persistent HPV infection in women aged 40 and older. A total of 131 women with long-lasting HPV were randomly assigned to receive the treatment or no treatment, and their HPV status was checked at 3, 6, and 12 months. The goal was to see if ablation increases viral clearance and whether DNA methylation patterns predict outcomes.
