A Pilot Study on Fertility Conservative Treatment of Atypical Endometrial Hyperplasia in Singapore
Study Details
Study Description
Brief Summary
The investigators' objective is to determine the regression rate, side effects and acceptability of Mirena compared to megace in the treatment of atypical endometrial hyperplasia among women desiring fertility.

Phase 2 |
Detailed Description
Atypical endometrial hyperplasia is a growing clinical problem that increases the risk of carcinogenesis and negatively impacts fertility. Although oral medical treatment may lead to regression in up to 90% of patients, they are associated with adverse side effects such as weight gain, that negatively affects fertility. To-date, there has been no RCTs evaluating the performance of the Mirena Intrauterine System (IUS) with megestrol acetate (megace) (the most effective and commonly used progestogen) in treating women with atypical hyperplasia who still desire fertility.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Mirena Arm The patients in the Mirena arm will have a Mirena inserted at time of recruitment of the study. An endometrial biopsy will be performed to assess for disease progression, regression or persistence after 3 months. The endometrial biopsy will be performed via bedside endometrial sampling or hysteroscopic biopsy. As Mirena can be used for treatment of atypical hyperplasia as well as endometrial protection (decreases the risk of endometrial hyperplasia recurrence), the option of keeping or changing the Mirena during biopsy will be discussed with the patient. |
Drug: Mirena
Mirena Intrauterine System (Mirena-IUS) is a levonorgestrel-releasing intrauterine system. Mirena consists of a T-shaped polyethylene frame (T-body) with a steroid reservoir (hormone elastomer core) around the vertical stem. The reservoir consists of a white or almost white cylinder, made of a mixture of levonorgestrel and silicone (polydimethylsiloxane), containing a total of 52 mg levonorgestrel. Mirena is approved for intrauterine contraception and in 2009 to treat heavy periods for women who choose intrauterine contraception. Mirena is often used off-label for the treatment of endometrial hyperplasia. Levonorgestrel is a progestogen used in a variety of contraceptive products. Low doses of levonorgestrel can be administered into the uterine cavity with the Mirena intrauterine delivery system. Mirena has mainly local progestogenic effects in the uterine cavity.
|
Experimental: Megace Arm The patients in the megace arm will have be prescribed 3 months of oral megace at time of recruitment of the study. An endometrial biopsy will be performed to assess for disease progression, regression or persistence after 3 months. The endometrial biopsy will be performed via bedside endometrial sampling or hysteroscopic biopsy. |
Drug: Megace
Megestrol acetate (Megace) is a synthetic derivative of the natural occurring steroid hormone, progesterone. It is licensed for the treatment of anorexia, cachexia or unexplained weight loss in patients with a diagnosis of acquired immunodeficiency syndrome (AIDS) and palliative treatment of advanced breast or endometrial cancer. Megace is often used off-label for the treatment of endometrial hyperplasia. While the precise mechanism by which Megace produces its antineoplastic effects against endometrial carcinoma and endometrial hyperplasia is unknown at the present time, inhibition of pituitary gonadotrophin production and resultant decrease in estrogen secretion may be factors. There is evidence to suggest a local effect as a result of the marked changes brought about by the direct instillation of progestational agents into the endometrial cavity.

Outcome Measures
Primary Outcome Measures
- Rate of Regression [Review in 3 months, maximum up to 9 months of treatment.]
Participants will be reviewed in clinic every 3 months. An endometrial biopsy via hysteroscopy or bedside endometrial sampling will be performed to assess persistence, progression or resolution of the disease.
- Time taken for regression of the disease [Review in 3 months, maximum up to 9 months of treatment.]
Participants will be reviewed in clinic every 3 months. An endometrial biopsy via hysteroscopy or bedside endometrial sampling will be performed to assess persistence, progression or resolution of the disease.
Secondary Outcome Measures
- Patient Acceptability [Review in 3rd months.]
Number of participants who are keen to continue their current treatment or change the treatment, at the end of 3rd months follow-up.
- Patient Acceptability [Review in 6th months.]
Number of participants who are keen to continue their current treatment or change the treatment, at the end of 6th months follow-up.
- Patient Acceptability [Review in 9th months.]
Number of participants who are keen to continue their current treatment or change the treatment, at the end of 9th months follow-up.
- Side Effects [Through study completion, an average of 9 months.]
Number of participants with side effects such as irregular bleeding, nausea/bloatedness or acne.
