This is a clinical practice guideline for women with cervical intraepithelial neoplasia (CIN). Recommendations are provided on the use of thermal ablation for the treatment of these women, with the ultimate goal of reducing the incidence of cervical cancer. The guideline compares thermal ablation to other treatment approaches such as cryotherapy, large loop excision of the transformation zone (LLETZ), and cold knife conization (CKC). Different modalities of thermal ablation (e.g., those that differ by temperature, number of applications, duration, etc.) are also discussed.
