OBJECTIVE: To evaluate the effectiveness of CO(2) laser ablation of vaginal intraepithelial neoplasia (VAIN) and to define prognostic factors.
STUDY DESIGN: Medical records of 24 patients with VAIN II or III, treated by CO(2) laser ablation from 1990 to 1998 were reviewed. The grade, location, and focality of the lesions, the age, follow-up period and menopausal status of the patients, the power and duration of laser ablation, the presence of concurrent cervical or vulvar neoplasia or previous hysterectomy were evaluated as possible prognostic factors.
RESULTS: Ablations of the VAIN were successfully accomplished in all of the patients with a mean period of 25.2+10.2 min, including additional simultaneous ablations of the cervix or vulva in eight (33.3%) patients. There was no early or late major complication. VAIN was completely eliminated in 17 (70.8%) patients after the first and in 19 (79.2%) patients after multiple episodes of ablation with a mean follow-up of 26.7+19.6 months. VAIN progressed to invasive vaginal carcinoma in one woman. None of the evaluated prognostic factors was found to be related to the persistence or recurrence.
CONCLUSION: CO(2) laser ablation was a safe and effective method for the treatment of VAIN. However, since no prognostic factor was defined, all patients should be closely evaluated for persistence, recurrence or progression to invasion.
