Proton beam therapy takes aim at rare skull base cancer
NCT ID NCT00496522
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 trial is testing whether proton beam therapy, a precise form of radiation, can control skull base chondrosarcoma after surgery. Fifteen participants who have had maximal surgical removal of their tumor will receive daily proton treatments for about 7 weeks. The study will track how long it takes for the cancer to come back and monitor side effects.
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 therapy (a type of radiation that uses protons instead of X-rays to target tumors precisely)
What this could lead to
If successful, this could show that proton beam therapy is an effective way to control skull base chondrosarcoma and delay or prevent its return after surgery.
What could go wrong
This is a small, early-phase trial with only 15 participants, so results may not apply to everyone. The treatment may not prevent recurrence and carries risks from radiation exposure to nearby brain structures.
