Atypical endometrial hyperplasia treatment with progestogens and gonadotropin-releasing hormone analogues: long-term follow-up

Abstract

Objective: The aim of this study was to assess the long-term effect of gonadotropin-releasing hormone analogues (GnRH-a) in combination with high-dose progestogens in the treatment of atypical endometrial hyperplasia in selected surgical high-risk patients and in women desiring reproductive potential. We hypothesized that this therapy is effective for most couples.

Methods: In the Department of Gynecology of a university hospital, a conservative treatment was offered to a series of 22 patients with atypical endometrial hyperplasia who had a surgical or anesthetic risk history or wished to preserve their fertility potential. After informed consent, they were treated with 500 mg norethisterone acetate weekly for 3 months and 3.75 mg Triptorelin depot every month for 6 months. Three patients failed to complete the study, so the group finally consisted of 19 subjects. They were prospectively followed for 5 years by hysteroscopy and multiple selected biopsies every 6 months.

Results: At a 5-year follow-up, regression was noted in 16 patients (84.2%), persistence in 1 (5.1%), recurrence in 1 (5.1%), and progression in 1 (5.1%).

Conclusion: Consistent with our hypothesis, combined treatment with progestogens and GnRH-a is an effective alternative in selected patients with atypical endometrial hyperplasia.
