Main Findings
The cumulative pathological cure rate of laser ablation for the treatment of VaIN in this study was 93.0%, which was higher than that in most studies reported. The high efficacy was attributed to the MTLA method. We proposed 3~5 circles of laser ablation for the HSIL(VaIN2,3) and 2~3 circles for the LSIL(VaIN1) patients to obtain a high pathological cure rate and HR-HPV clearance rate in our study.
