Conservative treatment of mild/moderate cervical dyskaryosis: long-term outcome.
There is some controversy about the management of women with mild or moderate dyskaryotic cervical smears. To assess the strategy of an established cervical cytology screening programme (Grampian region, northeast Scotland) we identified 500 women who had had mild or moderate cervical dyskaryosis in 1978 or 1979, and 500, matched by age, who had had a normal smear at that time. Follow-up smear results and any subsequent investigation by colposcopy, cone biopsy, or hysterectomy, with biopsy result were recorded. Of the 500 women who initially had an abnormal smear, 300 (60%) had a smear that was normal or inflammatory at their last visit (after seven years' median follow-up). 184 (37%) had undergone biopsy, 97 (19%) of whom were cervical intraepithelial neoplasia grade III or worse. Survival curves for time to biopsy and ten-year biopsy rates show that women with an abnormal smear before their baseline year were the most likely to have a subsequent biopsy. Older women had a biopsy less often and at biopsy were more likely to have minor abnormalities. Mild or moderate dyskaryotic smears should not be an indication for immediate referral for colposcopy, since under a conservative management policy most women return to normal without needing treatment. Nevertheless, the increased risk associated with abnormal smears justifies rigorous surveillance.
