Proton radiation in 5 or 25 treatments for skull-base tumors
Part of Cancer clinical trials.
This trial tests a radiation plan using protons given in either 5 or 25 sessions for chordoma or chondrosarcoma at the skull base. The goal is to shrink or control the tumor while protecting nearby critical nerves and brain structures.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have a confirmed biopsy diagnosis of chordoma or chondrosarcoma in the skull base
- You must have signed the trial consent form
- You need to be well enough to take part (Karnofsky performance score 70 or higher)
- Your MRI must not show blocked or narrowed blood vessels (stenosis or atherosclerosis)
- Your tumor volume must be 50 cc or less for the 5-session option, and the 25-session option requires being eligible after the screening scans
- Your treatment plan must be able to protect key nearby structures (optic nerves/chiasm, brainstem, spinal cord, and some side-of-brain areas) with specific dose limits

Other trials that look related to this one.
This trial is testing a better way to plan proton radiation using MRI images, aiming to deliver treatment more accurately for chordoma or chondrosarcoma in the spine/sacrum area. You may benefit if the trial’s planning method helps target the tumor while sparing nearby healthy tissue.
This trial is testing whether using only one proton beam per day is as safe and effective as using two beams for treating certain bone and spine tumors. It may help reduce treatment time and side effects.
This trial studies whether proton radiotherapy can treat primary brain (and sometimes spine) tumors in adults. You may join because your tumor type and situation fit specific diagnoses, including some cases needing a re-treatment plan.
This trial studies how detailed imaging can guide personalized (custom) radiation treatment for skull-base chordoma. It may help doctors plan treatment more accurately using measurements taken before and during therapy.
This trial tests a radiation plan that gives treatment in fewer, larger “fractions” using proton beams (or sometimes photon beams) for certain non-cancer brain tumor types. It aims to see how well this approach works while keeping side effects manageable.
This trial tests a special type of proton radiation for people whose spine cancer has spread from another part of the body and cannot be treated effectively with standard X-ray radiation. The goal is to see if proton radiation can safely deliver a high dose of radiation to the tumor.
