Reproductive and oncologic outcomes after progestin therapy for endometrial complex atypical hyperplasia or carcinoma.

Objectives: This study evaluated fertility and oncological outcomes in women with complex atypical hyperplasia (CAH) or nonmyoinvasive grade 1 endometrioid endometrial carcinoma (EM) who desired fertility-sparing therapy.

Study Design: The retrospective cohort study included women younger than 45 years with CAH or EM who desired fertility-sparing treatment at our institution. Only patients for whom both oncological treatment and pregnancy outcomes were available were included.
