The treatment of cervical intraepithelial neoplasia by laser vaporization.

Of 711 women with cervical intraepithelial neoplasia (CIN) treated by laser vaporization 675 (95%) remain colposcopically and cytologically free from disease after a median follow-up of 20 months. Thirty-six patients needed other forms of treatment to eradicate suspected residual disease. One patient presented with invasive carcinoma of the cervix 34 months after treatment with the carbon dioxide laser. It is concluded that in selected cases laser vaporization is an effective method of treating pre-invasive disease of the cervix.
