Endometrial Neoplasm Malignant Stage I

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.

The goal of this clinical trial is to explore the feasibility and outcome of fertility-sparing therapy in Stage IA G1-G2 Endometrial Cancer with less than 1/2 myometrial invasion. Researchers will render participants indication-extended fertility-sparing therapy. Researchers will compare the myometrial invasion group with the no myometrial invasion group to see if it is possible to propose an extension indication of fertility-sparing therapy for endometrial cancer.
