Summary

This study is for women with a certain type of endometrial cancer (called MMR-D/MSI-H) who have already had surgery. It tests whether adding radiation and an immunotherapy drug called dostarlimab can help keep the cancer from coming back. About 62 participants will receive the combination treatment, and researchers will monitor side effects and how long they stay cancer-free.

What this could mean

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

Active substance

Dostarlimab (a drug that helps the immune system fight cancer) and radiation therapy

What this could lead to

If it works, this could offer a new way to reduce the risk of cancer coming back after surgery for women with this specific type of endometrial cancer.

What could go wrong

This is a small, early-phase trial with only 62 participants, so results may not apply to everyone. The combination of radiation and immunotherapy may cause side effects like fatigue or immune reactions.
