Management of women with a cervical smear showing a mild degree of dyskaryosis: a review of policy.

Three hundred and thirty-seven women who presented for the first time with a cervical smear showing a mild degree of dyskaryosis were followed for a minimum period of 3 years and 9 months. Of the 305 women with complete cytological and histological records, 178 were biopsied and 127 remained on cytological follow up. In the biopsied group one case of microinvasive squamous cell carcinoma was diagnosed within 1 year of the patient's first abnormal smear. A further 24% showed cervical intraepithelial neoplasia (CIN) I, 17% showed CIN II and 29% showed CIN III. The overall regression rate for the group of 305 women was 34%. Our results indicate that cytological surveillance is acceptable provided that biopsy is advised when dyskaryosis persists. No major modifications to laboratory policy are indicated and in approximately 34% of cases an unnecessary hospital referral would be avoided.
