Abstract
- Background: Ablative treatment of anal high-grade squamous intraepithelial lesions (HSIL) reduces the risk of progression to anal squamous cell carcinoma. Objectives: To identify factors that influence the response to treatment of anal HSIL by electrocautery ablation (ECA) in a population of HIV-positive men who have sex with men (MSM). Design: Retrospective study of ECA treatment response in a prospectively followed anal dysplasia cohort. HIV-positive MSM diagnosed with anal HSIL were included. Demographic and HIV data were recorded. Response to treatment was assessed by biopsy after at least 18 months of follow-up. Results: One hundred and twenty-eight HSILs in 91 men were included in this study. The overall response rate at 18 months was 70.3%. The number of electrocautery sessions required (2 ECA sessions vs 1: adjusted odds ratio [aOR] = 0.36 (95%CI 0.13-1.01); >=3 sessions vs 1: aOR = 0.10 (95%CI 0.04-0.29); p < 0.001]) and the history of previous HPV-related anal pathology (previous anal lesions vs no previous lesions AOR = 2.83 (95%CI 1.14-7.02), p = 0.024) were independently associated with response at 18 months. No serious adverse events were reported. Conclusions: Consideration should be given to alternative therapies in patients with unresolved HSIL after 1 ECA treatment. [ABSTRACT FROM AUTHOR]
