Low-grade cervical squamous intraepithelial lesion during pregnancy: conservative antepartum management

The purpose of this retrospective study was to determine the regression rate and management of low-grade squamous intraepithelial lesions (LSIL) in pregnancy. Seventy-four women with cytological findings of LSIL were analysed during the pregnant-puerperal period (until 12 months postpartum). Age, parity, cytological and colposcopic findings, route of delivery, and postpartum follow-up were studied. The age and parity of patients ranged (average) from 12 to 32 years (21.2 +/- 4.9), 0-5 (0.89 +/- 1.14), and 9-32 years (16.1 +/- 3.5), respectively. Thirty-nine of 55 (70.9%) and 12 of 19 (63.1%) pregnant women had normal cytology after vaginal delivery and caesarean section, respectively (p > 0.05). In postpartum, eight patients (10.8%) persisted with LSIL and ten (13.5%) presented high-grade squamous intraepithelial lesions. No case of unsatisfactory colposcopy and invasive carcinoma were found. LSIL during pregnancy has a high rate of regression, regardless of the route of delivery. Conservative management with colposcopic evaluation is proposed during gestation.
