- Abstract
- Objective
To evaluate adverse obstetric outcomes in women with a history of endometrial cancer (EC).
Design
Population-based cohort study.
Setting
The Korean National Health Insurance (KNHI) claims database.
Population
Women who gave birth between 2009 and 2016, with a history of EC prior to pregnancy.
Methods
The KNHI database was used to compare obstetric outcomes of women with and without a history of EC, using the ICD-10 codes. Multivariable logistic regression models were used to determine the associations between a history of EC and adverse obstetric outcomes.
Main outcomes measures
Adverse obstetric outcomes.
Results
Overall, 248 and 3 335 359 women with and without a history of EC, respectively, gave birth. When adjusted for age, primiparity and comorbidities, an increased risk of multiple gestations (odds ratio [OR] 4.925, 95% confidence interval [CI] 3.394–7.147), caesarean delivery (OR 2.005, 95% CI 1.535–2.62) and preterm birth (OR 1.941, 95% CI 1.107–3.404) was observed among women with a history of EC. We were unable to demonstrate significant differences in the risk of pre-eclampsia, gestational diabetes, vacuum delivery, placenta praevia, placenta accreta spectrum, placental abruption and postpartum haemorrhage between the groups. In the sensitivity analyses excluding multiple gestations, an increased risk of preterm birth was not observed among women with a history of EC (OR 1.276, 95% CI 0.565–2.881).
Conclusions
There is no convincing evidence of an increased risk of adverse obstetric outcomes among women with a history of EC. Our findings would be useful in counselling of patients with EC who are undergoing fertility-sparing treatment.
