Cervical dysplasia in pregnancy: a multi-institutional evaluation.
OBJECTIVE
This study was undertaken to identify the prognostic indicators associated with postpartum regression of cervical dysplasia diagnosed in pregnancy.


METHODS
A retrospective cohort study of pregnant women referred for colposcopy from 2004-2007 at four academic centers.


RESULTS
One thousand seventy-nine patients were identified. Colposcopic impression by cervical cytology is detailed later in the text. Of patients who underwent biopsy, results correlated with or were less severe than colposcopic impression in 83% with CIN 1 and 56% with CIN 2/3. Fifty-seven percent had follow-up postpartum, with 61% reverting to normal. Resolution of cervical dysplasia was inversely associated with smoking (P = .002). No progression to cancer occurred during pregnancy.


CONCLUSIONS
Colposcopic impression in pregnancy correlated with cervical biopsy results and postpartum colposcopic findings when performed by expert colposcopists. A high proportion of cervical dysplasia regressed postpartum. Cervical biopsies in pregnancy may not be necessary unless invasive cancer is suspected.
