Pregnancy complications and outcomes in patients with early endometrial cancer or atypical hyperplasia after fertility-sparing treatment

Assisted reproductive technology including IVF-ET and ovulation induction might be preferred for patients with EEC/EAH after successful fertility-sparing treatment to achieve a relatively better pregnancy outcome, though IVF-ET has a higher incidence risk of threatened abortion, preterm birth and placenta accreta/increta. Obstetricians should be prepared for the treatment of threatened abortion, cervical insufficiency, and placenta accreta/increta in patients with EEC/EAH once they become pregnant, especially in those receiving more than 5 times of hysteroscopic evaluation.
