Brief summary
The study aims to show that treatment with LtAPD works better than a sham treatment or simply monitoring the condition closely without active treatment ("active surveillance"), in achieving complete healing of a tissue abnormality on the cervix called CIN 2, after 6 months. This will be confirmed by examining tissue samples under a microscope (histopathological examination).
Detailed description
Participation in the study lasts 6 months. Eligible participants are randomly assigned to one of two groups: participants receiving LtAPD treatment (treatment group) or participants receiving a sham procedure, in which LtAPD treatment is simulated but not actually applied (control group). All participants continue to be managed according to the current standard of care, active surveillance with regular monitoring, throughout the study. Participants remain blinded to their treatment assignment. The study includes four visits.
Interventions
Single session of LtAPD treatment applied to the CIN2 lesion under colposcopic guidance; outpatient, no anesthesia required.
Single session of sham treatment (no argon gas delivery and plasma ignition; acoustic signal to maintain blinding) followed by active surveillance according to current clinical guidelines.

Secondary
| Measure | Time frame | Description |
|---|---|---|

| Cytological remission of CIN | at 6 months | Percentage of patients with cytological remission, assessed by Papanicolaou (PAP) smear according to the Bethesda classification system |
| Quality of life, comfort/ discomfort of the treatment procedure and sexual activity | at baseline, intervention, 6 months | Change from baseline in quality of life and sexual health at baseline and 6 months, assessed by the Freiburg Index of Patient Satisfaction (FIPS) and the Sexual Activity Questionnaire (SAQ) |
| Correlation of electrosurgical unit (ESU) and video data with CIN remission and applied argon plasma | at 6 months | assessed by correlation of ESU and video data with CIN remission and applied argon plasma |
