New proton therapy could shrink skull tumor treatment to just 5 days

NCT ID NCT05861245

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase II trial is testing a shorter course of proton therapy for people with chordomas or chondrosarcomas at the base of the skull. Instead of many sessions, patients receive radiation in just 5 consecutive days. The goal is to see if this approach is safe, controls tumor growth, and improves quality of life. The study is currently recruiting 20 participants.

What this could mean

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

Active substance
Proton therapy (radiation) given in 5 sessions
What this could lead to
If successful, this could offer a shorter, more precise radiation treatment for skull base tumors, potentially reducing side effects and improving quality of life.
What could go wrong
This is a small early-phase trial with only 20 participants, so results may not apply to everyone. The treatment still carries risks of radiation side effects, and it is not a cure.
