Carcinoma, Endometrioid

Endometrial cancer (EC) is a prevalent gynecological cancer with an escalating global incidence and a decreasing age of onset. In the era of precision medicine, there is an increasing emphasis on tailoring treatments to different populations to optimize the positive impact of clinical interventions. Fertility-sparing therapies (FST) are gaining popularity for early-stage, low-grade endometrial cancer due to mounting evidence supporting favorable oncologic and pregnancy outcomes. However, consensus regarding the feasibility of fertility-sparing therapy for similar low-risk grade-2 (G2) endometrioid adenocarcinoma remains elusive. Given the uncertainties surrounding fertility-preserving therapy in patients with moderately differentiated endometrial cancer, this study aims to investigate the optimal regimen of fertility-preserving therapy for patients with IAG2.

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.
