[Cryosurgery for dysplasia, carcinoma in situ, and microinvasive carcinoma of the uterine cervix (author's transl)].

Abstract

One hundred and three patients with dysplasia, carcinoma in situ, or microinvasive carcinoma of the uterine cervix were treated with cryosurgery during 8 years from 1972 to 1978. Twenty-nine patients underwent several types of operations during 4-41 days (mean 18 days) after cryosurgery, and 74 patients were followed for 3-78 months (mean 3 years) after treatment. Seventy-six per cent of the patients who underwent an operation had residual lesions in their histologic materials. Seventy per cent of the patients who were followed, on the other hand, showed consecutively negative cytology and pathology after cryosurgery. It is necessary for the more effective management of CIN with cryosurgery to perform endocervical curettage in every case, to select small lesion for treatment, and to use more powerful method of cryocauterization.
