Proton beam therapy tested for liver cancer – early results show promise and risks
NCT ID NCT04805788
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase II trial tested a precise type of radiation called proton beam therapy in 9 people with liver cancer. The goal was to see if it could control the cancer while limiting damage to the liver. The study was stopped early, so the findings are limited, but early data suggest it may be a useful option for some patients.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Proton beam radiotherapy
- What this could lead to
- If successful, this could show that proton radiotherapy is a safe and effective way to treat liver cancer with fewer side effects than standard radiation.
- What could go wrong
- This was a very small, early-phase trial that was terminated early, so results are limited. Proton therapy may still cause liver damage or other side effects.
