Radiation after thymoma surgery: could it keep cancer away?

NCT ID NCT02633553

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looks at whether giving radiation therapy after complete surgical removal of stage II or III thymoma helps prevent the cancer from returning. About 238 adults aged 18 to 75 who had their tumor fully removed will be randomly assigned to receive either radiation or no additional treatment. The main goal is to see if radiation improves how long patients 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

adjuvant radiotherapy (radiation therapy)

What this could lead to

If successful, this could show that adding radiotherapy after surgery reduces the chance of thymoma coming back and improves long-term survival.

What could go wrong

This is a phase III trial, but it is still recruiting and results are not yet known. Radiotherapy can cause side effects like fatigue or damage to nearby organs, and it may not provide a clear benefit over surgery alone.
