title: The effect of delivery on regression of abnormal cervical cytologic findings.
abstract: The purpose of this study was to determine whether abnormal antepartum cervical cytologic findings result in differing postpartum regression rates. Between 1993 and 2000, 107 pregnant women with antepartum abnormal cervical cytologic findings were identified. Papanicolaou smear data were separated into three groups by use of the CIN classification system. Postpartum regression rates of antepartum Papanicolaou smears were analyzed six months after delivery. Normalization of Papanicolaou smears in the postpartum period were observed in 50 of 107 women (46.7%). Regression of cervical cytologic findings was noted in 61 of 107 women (57%). Respectively, persistence of Papanicolaou smear was noted in 43 of 107 patients (40%). Only 3 of 107 (3%) antepartum findings progressed after delivery. Desquamation of the cervical epithelium or enhancement of a localized reparative immunologic response after vaginal delivery could play an important role in the spontaneous regression of cervical dysplasia in the postpartum period.
