Cervical Cancer and Risk for Delivery of Small-for-Gestational Age Neonates.

Objective: To determine if cervical intraepithelial neoplasia grade 3 (CIN-3) and cervical cancer are associated with adverse obstetrical outcomes. Methods: Women with diagnoses of CIN-3 and cervical cancer were first identified from the University of Pittsburgh Medical Center (UPMC) Network Cancer Registry by using respective ICD-3 codes. Identified records were then linked to the Magee Obstetrical Maternal and Infant (MOMI) database to identify women who subsequently delivered pregnancies at Magee-Womens Hospital. Women with cervical disease were compared with women without known disease to determine the impact of cervical disease on various maternal and neonatal outcomes. The latter group consisted of those women who delivered singleton pregnancies at our institution, as determined by the MOMI database, but who did not have any matching records in the UPMC Cancer Registry. Statistical significance was defined by a p value <0.05. Results: We identified CIN-3 ( n = 52) and cervical cancer patients ( n = 83) who later had documented pregnancies delivered at Magee-Womens Hospital between 1989 and 2006. Women with cervical cancer and CIN-3 were at greater risk to deliver small-for-gestational age (SGA) neonates compared with women without known cervical disease (RR 1.54, 95% confidence interval [CI] 1.0-2.46). A secondary analysis of risk factors for SGA neonates demonstrated a significant association with cervical cancer ( p = 0.04). After accounting for variables known to be risk factors for SGA, cervical cancer was associated with a 1.9-fold increased risk of a SGA delivery (OR 1.9, 95% CI 1.1-3.4). Conclusions: Cervical cancer is a risk factor for delivery of an SGA neonate in a subsequent pregnancy. [ABSTRACT FROM AUTHOR]
