title: [Histological evaluation of cryosurgery in high grade intraepithelial neoplasia (CIN-III)] of the uterine cervix].
abstract: Sixty patients, having high grade cervical intraepithelial neoplasia (CIN III) are analyzed. They are all treated primarily with cryosurgery followed, approximately 12 weeks thereafter, by cervical conization, in order to histologically evaluate the response to treatment. The mean follow up of the whole series was 36 months. Ninetieth five percentage of the patients were included in the series, having an abnormal PAP smear, suggesting presence of a CIN. Colposcopically directed biopsy prior to cryosurgery showed grade CIN III, with no glandular involvement in 61.7% of the cases. In 38.3% the endocervical glands were involved, cryotherapy was done in 60 patients, with single freezing in 26 (43.3%) and double freezing in 34 (53.7%) patients. On analyzing the cone specimen, 71.7% of the cases showed no residual disease. The group that received double freezing did better than the single one (79 versus 61%). As well, the group with out gland involvement did better than the group showing such condition (83.8 versus 52.2%). Cryosurgery is a good therapeutic modality in cases with CIN III, following street selection criteria and having a good and reliable follow up.
