BACKGROUND: Thermal coagulation is gaining popularity for treating cervical intraepithelial neoplasia (CIN) in screening programs in low- and middle-income countries (LMICs) due to unavailability of cryotherapy. OBJECTIVES: Assess the effectiveness of thermal coagulation for treatment of CIN lesions compared with cryotherapy, with a focus on LMICs. SEARCH STRATEGY: Papers were identified from previous reviews and electronic literature search in February 2018 with publication date after 2010. SELECTION CRITERIA: Publications with original data evaluating cryotherapy or thermal coagulation with proportion of cure as outcome, assessed by colposcopy, biopsy, cytology, and/or visual inspection with acetic acid (VIA), and minimum 6 months follow-up. DATA COLLECTION AND ANALYSIS: Pooled proportions of cure are presented stratified per treatment modality, type of lesion, and region. MAIN RESULTS: Pooled cure proportions for cryotherapy and thermal coagulation, respectively, were 93.8% (95% CI, 88.5-97.7) and 91.4% (95% CI, 84.9-96.4) for CIN 1; 82.6% (95% CI, 77.4-87.3) and 91.6% (95% CI, 88.2-94.5) for CIN 2-3; and 92.8% (95% CI, 85.6-97.7) and 90.1% (95% CI, 87.0-92.8) for VIA-positive lesions. For thermal coagulation of CIN 2-3 lesions in LMICs 82.4% (95% CI, 75.4-88.6). CONCLUSIONS: Both cryotherapy and thermal coagulation are effective treatment modalities for CIN lesions in LMICs.
