Perinatal High-Grade Cervical Cytology: A Case Series From a Safety Net Institution

To describe the outcomes of women with high-grade cervical cytology in pregnancy and to identify factors that predict completion of appropriate postpartum follow-up.

We describe a case series of all patients with high-grade cervical cytology collected during pregnancy between 2007 and 2011 at a single institution. Patients were considered adherent with follow-up if they received any kind of postpartum evaluation or treatment for their cervical dysplasia at our institution within 9 months of delivery.

Of 138 women with high-grade cervical cytology in pregnancy, 87 (63%) had high-grade squamous intraepithelial lesion, 47 (34%) had atypical squamous cells that cannot rule out high-grade (ASC-H), and 4 (3%) had atypical glandular cells (AGC). Most patients (81%) underwent colposcopy during pregnancy. A total of 48 patients (43%) had biopsies performed, 26 (54%) were CIN 2 or 3, and one (2%) was adenocarcinoma in situ (AIS). A total of 97 (70%) of 138 patients completed recommended postpartum follow-up, resulting in the detection of one additional case of AIS and one case of invasive adenocarcinoma. Hispanic ethnicity (odds ratio [OR], 3.6; confidence interval [CI], 1.4-9.1), being married (OR, 4.5; CI, 1.6-12.4), being employed (OR, 3.7; CI, 1.3-10.5), and CIN2 or 3 on antenatal biopsy (OR, 9.8; CI, 2.0-47.9) were all significantly associated with completion of postpartum follow-up.

Colposcopy during pregnancy resulted in the detection of one case of AIS. Postpartum evaluation and treatment detected an additional case of AIS as well as one case of invasive cervical adenocarcinoma. Whereas certain demographic characteristics were associated with completion of recommended follow-up, the strongest association is with a high-grade biopsy during pregnancy.
