Outcomes of extended progestin therapy in atypical endometrial hyperplasia patients without an initial response to progestin: a retrospective study from two tertiary centers in Korea and Taiwan

In this study, we evaluated the role of prolonged progestin treatment on atypical endometrial hyperplasia (AEH) patients who did not achieve complete regression (CR) after at least 3 months of progestin treatment. Possible prognostic factors predicting disease regression and recurrence were also assessed.
