Gonadotropin-releasing Hormone Agonist (GnRHa) Plus Letrozole In Young Women With Early Endometrial Cancer

Summary

To see if Gonadotropin-releasing hormone analogue (GnRHa) combined with aromatase inhibitors (AIs) will achieve better complete response rate than megestrol acetate or medroxyprogesterone acetate (MA/MPA) alone as fertility-sparing treatment for patients with early endometrial carcinoma.
