Summary
Cryosurgery effectively treats human papillomavirus (HPV) lesions, offering good results. Adjuvant alpha-2-interferon is recommended for patients with extensive or persistent HPV infections.
Area of Science:
- Dermatology
- Oncology
- Virology
Background:
- Human papillomavirus (HPV) infections can cause significant morbidity.
- Cryosurgery is a common treatment modality for HPV lesions.
- Adjuvant therapies are explored to improve treatment outcomes.
Purpose of the Study:
- To evaluate the effectiveness and limitations of cryosurgery for HPV lesions.
- To define indications for adjuvant systemic alpha-2-interferon (a2-IFN) therapy.
Main Methods:
- A retrospective study of 123 patients with genital, anorectal, and perineal HPV lesions treated with cryosurgery.
- 38 patients received adjuvant systemic a2-IFN.
- Clinical examinations, cytology, PCR, and histology were utilized.
Main Results:
- 79.7% of patients remained recurrence-free after a median follow-up of 32 months.
- Recurrence was associated with female gender, longer symptom duration, wider lesions, head and neck involvement, and HIV positivity.
- Multivariate analysis identified symptom duration, head and neck involvement, and lesion width (>3 sq cm) as significant risk factors for recurrence.
Conclusions:
- Cryosurgery is a valuable treatment for HPV lesions, providing good cosmetic and functional outcomes.
- Adjuvant a2-IFN may benefit patients with multiorgan involvement, specific HPV types (16/18), large lesions, long-standing symptoms, or SIL.
