Conditions

Atypical Endometrial Hyperplasia

Brief summary

To verify whether metformin could improve the effect of progestin as fertility-sparing treatment in patients with atypical endometrial hyperplasia(AEH).

Detailed description

Whether metformin could improve the effect of progestin as fertility-sparing treatment in patients with atypical endometrial hyperplasia(AEH) is still not clear. Our previous finding from subgroup analysis in a phase II randomized controlled trial showed that 39.6% of AEH patients in metformin plus megestrol acetate group achieved complete response, compared with 20.4% in group of megestrol acetate alone. This trial aim to fully testify the effect of metformin in fertility-sparing treatment for AEH patients with adequate sample size.
