Abstract

Objective: In this study, we evaluated the management of cervical intraepithelial neoplasia (CIN) in pregnant women and evaluated the postpartum prognosis. Methods: Twenty-four pregnant women, who were diagnosed with CIN at Ehime University Hospital between January 2008 and October 2012, were recruited. The mode of delivery and pathophysiological examination results in the postpartum period were evaluated. Results: Four patients were antenatally diagnosed with either CIN1 or CIN2. Of these patients, CIN regressed or remained stable during pregnancy, and there was no disease progression in the postpartum period. Nine patients were diagnosed with severe dysplasia (CIN3) and eleven patients had carcinoma in situ (CIS). Of these patients, 5/9 (55%) and 4/11 (36%), respectively, had disease regression postnatally. No CIN lesion progressed to invasive carcinoma after delivery. Conclusions: We determined that many cases diagnosed antenatally with CIN regressed during the postpartum period, regardless of the grade of CIN. We recommend a conservative management strategy with careful ante- and postpartum examinations for pregnant women with CIN.
