Can hormone therapy spare fertility in a challenging endometrial cancer?

NCT ID NCT06468215

First seen Aug 18, 2026 ยท Last updated Aug 18, 2026

Summary

This trial is testing two hormone-based approaches to treat early-stage, grade 2 endometrial cancer in women under 45 who wish to preserve their fertility. One approach uses a daily oral progesterone pill, while the other combines the pill with a hormone-releasing intrauterine device (Mirena IUD). The goal is to see which regimen leads to complete remission of the cancer faster and with a lower chance of recurrence, offering a potential alternative to hysterectomy for these patients.

What this could mean

Our plain-language read of the trial. This is informational only โ€” not medical advice or a prediction.

Active substance
Progesterone therapy (medroxyprogesterone acetate or megestrol acetate) alone or combined with a levonorgestrel intrauterine system (Mirena IUD)
What this could lead to
If successful, this could establish a standard fertility-sparing treatment for grade 2 endometrial cancer, allowing young women to preserve their fertility while effectively managing the disease.
What could go wrong
This is a small, early-phase trial with only 16 participants, so results may not be conclusive. The treatment may not achieve complete remission in all cases, and there is a risk of recurrence or progression, which could require more aggressive surgery.
