Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this study was to investigate the feasibility of a PD-1 inhibitor in combination with progesterone as a means of preserving fertility in patients with early-stage mismatch repair-deficient (MMRd) endometrial cancer who wish to preserve fertility.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Endometrial cancer (EC) is a prevalent gynecological cancer with an escalating global incidence. The standard treatment for endometrial cancer is total hysterectomy and bilateral salpingo-oophorectomy. However, given the rising incidence of endometrial cancer in younger individuals and the the delay in the age of human reproduction, the conservation of endometrial cancer has garnered heightened attention. Clinical practice has demonstrated that high-dose progesterone can reverse the lesioned endometrium, thereby providing a rationale for the conservative treatment of early-stage endometrial cancer.

PD-1 inhibitor has been utilized as a salvage treatment in many cancers including ovarian cancer, cervical cancer, lung cancer, gastric cancer and endometrial cancer. As endometrial cancer showed MMRd rates, it is assumed to be highly responsive to PD-1 inhibitor treatment. Previous literature has reported that the efficacy of progesterone therapy is limited in patients with a MMRd status.Here we want to investigate the feasibility of PD-1 inhibitor combined with progesterone in early stage endometrial cancer patients who want to preserve fertility.
