title: Conservative management of the abnormal smear during pregnancy. A long-term follow-up.
abstract: One hundred and thirty-two pregnant women who had a smear suggestive of cervical intra-epithelial neoplasia (CIN) II or more during the 10th to 12th gestational week, were followed with repeated smears and colposcopy every month and, when indicated, a colposcopically guided biopsy. Post-partum follow-up included cytology, colposcopy, portio biopsies and endocervical curettage. Seventy-nine women with normal findings post partum were checked once a year in a long-term study. A close correlation (71% of CINIII) was found between cytological and histological diagnoses in cases of persistent (three or more) abnormal smears. However, in women with regression of the cytological diagnosis, high frequencies of histologically verified CIN were found. Thus, 37.5% (18/48) of normal or CINI smears were histologically still CINIII. Histologically verified CIN during pregnancy, on the other hand, showed a post partum progression of two degrees or more of CIN in only two cases. Cytology seemed to be inappropriate post partum, with 23.3% smears which were normal or suggestive of CINI, when histology showed CINIII. In a long-term follow-up, 24% of women with a normal post partum follow-up for at least one year had a subsequent recurrence of CIN. It is concluded that follow-up of abnormal smears during pregnancy with repeated smears is not a reliable method. Post-partum follow-up should include at least colposcopy and a biopsy when indicated by the colposcopical examination. Women with a normal post partum follow-up constitute a high risk group for future recurrence of CIN and should be carefully followed for at least 5 years.
