Even though malignant potential of vaginal intraepithelial neoplasia(VaIN) may be low, the prevalence is increasing and the mean age at diagnosis is decreasing. Various treatment options have been used for the eradication of ValN, but most effective standard protocol is not present because it is a rare disease. Laser vaporization was used to treat 7 patients with VaIN diagnosed at Department of Obstetrics and Gynecology, Seoul National University Hospital between 1992 to 1996. The patients were from 40 to 70 years of age with a mean 57 of years. All patients had a history of radical or simple hysterectomy, and final pathologic diagnosis were as follows : cervical cancer(n=5), cervical intraepithelial neoplasia(n=l), leiomyoma(n=l). Vaginal intrae-pithelial neoplasia(VaIN) was identified between 4 months and 8 years after first operation. All lesions were unifocal disease and found at the upper one third of the vagina. Treatment was performed with a CO2 laser unit and colposcope. Four(57%) out of seven patients had general anesthesia for the purpose of treatment. Patients were followed up for an average of 16.8 months with regular cytologic evaluation, colposcopy and biopsy. Failure of therapy was defined as evidence of intraepithelial neoplasia in any one of these three parameters. Only one patients showed persistent disease and the others remain free of disease. The success rate of therapy was 85.7%(6/7). (continue)
