Background: Men who have sex with men have increased prevalence of both human papillomavirus and anogenital condyloma.
Objective: Risk factors for multiple treatment and recurrence of anal condyloma were examined.
Design: This is a retrospective study of HIV-negative men who have sex with men who were treated for anal condyloma.
Settings: This study was conducted in a private surgical practice.
Patients: The patients were HIV-negative men who have sex with men, aged 18 years or older.
Intervention(s): Ablation with electrocautery or CO2 laser was performed, as well as excision and topical imiquimod condyloma treatment adjuvant.
Main outcome measures: Primary clearance, defined as 4 months of condyloma-free survival posttreatment, and recurrence, defined as any anal condyloma diagnosis after primary clearance.
Results: Of 231 participants, 207 achieved primary clearance (median age, 32.0 years) and were followed (median, 18.2 months) after primary treatment. Most had intra-anal and perianal condyloma (56%), were treated with electrocautery ablation (79.2%), and required 1 treatment (range, 1-6) for clearance. There were 57 recurrences (median, 12 months). One-third each had minimal, moderate, or extensive disease. Forty-six percent of patients received imiquimod posttreatment adjuvant. High-grade dysplasia was found in 31% at presentation and 43% during follow-up. Factors associated with requiring multiple treatments for clearance were participants having moderate disease (adjusted odds ratio, 6.0 (1.7-21.4)) and receiving imiquimod adjuvant (adjusted odds ratio, 4.7 (2.0-10.6)). No single factor predicted recurrence, but those with moderate disease experienced recurrences significantly sooner (median, 25 months of follow-up).
Limitations: This was a retrospective chart review, it was limited to a single practice, and it excluded those who did not achieve primary clearance.
Conclusions: Most men who have sex with men have intra-anal and perianal condyloma and concomitant high-grade dysplasia is common. Most achieved clearance with 1 treatment. Having both intra-anal and perianal condyloma, increased severity of disease, and imiquimod adjuvant were significant predictors of requiring multiple treatments for clearance. No identified risk factors proved a significant predictor of recurrence.
