About

To explore the treatment efficacy of Progesterone Therapeutic Regimen Plus Azelnidipine in patients with atypical endometrial hyperplasia (AEH) and early endometrial carcinoma (EEC) for conservative treatment.

Full description

After diagnosed of AEH or EEC by hysteroscopy, patients meet the study criteria will be enrolled. The age, height, weight, waistline, blood pressure, drug load, basic history of infertility and family cancer will be collected. Blood tests, including calcium, albumin, fasting blood glucose (FBG), fasting insulin (FINS), blood lipids, sex hormone levels, anti-müllerian hormone (AMH) and renal/liver function tests will be performed before treatment to evacuate their basic conditions.

Patients with endometrial cancer who met the inclusion criteria were randomly divided into the control group and the experimental group in a 1:1 ratio according to the random numbers generated in advance. The administration regimen for the two groups was as follows:

Control group: progesterone regimen (oral medroxyprogesterone acetate tablet 250mg-500mg/ day or Mirena +GnRHa 3.75mg subcutaneous injection monthly); Trial group: progesterone regimen (oral medroxyprogesterone acetate tablet 250mg-500mg/ day or Mirena +GnRHa3.75mg subcutaneous injection monthly) combined with Azelnidipine (oral Azelnidipine 8mg/ day); The specific selection of progesterone regimen was based on whether the patients had oral progesterone contraindications and if BMI≥28kg/m2 was not suitable for oral progesterone, Mirena +GnRHa regimen was selected. The choice of Azelnidipine is based on the results that Azelnidipine can inhibite growth in several endometrial cancer cells, PDX model and patient-derived cells.

For patients remained SD after 9 months of treatment but refused hysterectomy, a multiple disciplinary discussion would be held for individual case, and alternative treatment would be given. Maintenance treatment will be recommended for patients with CR, and participants will be followed up for at least 1 year.
