Abstract

OBJECTIVE: To study whether a treatment of cervical intraepithelial neoplasia (CIN) is associated with an adverse outcome in the subsequent pregnancies. METHODS: This study is a register-based retrospective cohort study from Finland. National data of 25,827 women having a surgical treatment of the cervix for CIN in 1986-2003 and their 8,210 subsequent singleton births in 1987-2004 were studied. Main outcome measures were preterm birth rate, low birth weight rate, and perinatal mortality rate. RESULTS: The risk of any preterm delivery (less than 37 weeks of gestation), especially the risk of very preterm delivery (28-31 weeks of gestation), and extremely preterm delivery (less than 28 weeks of gestation) was increased after cervical conization (relative risk [RR] 1.99, 95% confidence interval [CI] 1.81-2.20; RR 2.86, 95% CI 2.22-3.70; and RR 2.10, 95% CI 1.47-2.99, respectively). After cervical ablation, the risk of preterm delivery was also increased. The risk of low birth weight and perinatal death was increased after conization (RR 2.06, 95% CI 1.83-2.31 and RR 1.74, 95% CI 1.30-2.32, respectively). Adjusting for maternal age, parity, and maternal smoking did not affect our results. CONCLUSION: Any treatment for CIN, including loop electrosurgical excision procedure, increases the risk of preterm delivery. It is important to emphasize this when treating young women with CIN. LEVEL OF EVIDENCE: II.

  • History of cervical cone biopsy or loop electrocautery excision procedures and various uterine anomalies are associated with an increase in spontaneous preterm delivery.

    “History of cervical cone biopsy sample or loop electrocautery excision procedures secondary to premalignant cervical disorders have also been associated with an increase in spontaneous preterm delivery, as have various anomalies of the uterus itself—such as the presence of a septum.44”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
