A Prospective Phase II Randomized Trial to Compare Intensity Modulated Proton Radiotherapy (IMPT) vs. Intensity Modulated Radiotherapy (IMRT) for Newly Diagnosed Glioblastoma (WHO Grade IV)
Study Groups:
If you are found to be eligible to take part in this study, you will be randomly assigned
(as in the flip of a coin) to 1 of 2 study groups. You will have an equal chance of being
assigned to either group.
If you are in Group 1, you will receive IMRT.
If you are in Group 2, you will receive IMPT.
Radiation Therapy:
In both groups, you will receive radiation treatments each day, Monday-Friday, starting on
Day 1. You will continue to receive radiation treatment until you have completed 30 total
treatments. This is a total of up to 6 weeks of treatment.
You will sign a separate consent form for the IMRT or IMPT that will explain the procedures
and risks in detail.
Study Visits:
Before beginning radiation, you will have what is called a "simulation" to plan your
radiation. During the simulation, you will be flat on your back on a computed tomography
(CT) table and a soft plastic mask will be made to help hold your head still during
treatment. This is the position you will be in when you receive radiation treatment. You
will then have a CT scan, which will make computerized images to help plan your treatment.
At Month 2 (+/- 14 days):
- You will have a physical exam, including measurement of your vital signs.
- You will have an MRI to check the status of the disease.
- You will be asked about any drugs you may be taking and side effects you may be having.
- You will complete the thinking skills tests and the questionnaires about your quality
of life and symptoms.
Length of Treatment:
You may receive up to 6 weeks of radiation therapy. You will no longer be able to receive
radiation therapy if the disease gets worse, if intolerable side effects occur, or if you
are unable to follow study directions.
Your active participation on the study will be over after the follow-up visits.
Follow-Up:
At Month 4 (+/- 14 days) and then every 2 months for up to 2 years after radiation therapy:
- You will have a physical exam, including measurement of your vital signs.
- You will be asked about any side effects you may be having.
- You will have an MRI to check the status of the disease.
- You will complete the thinking skills tests and the questionnaires about your quality
of life and symptoms.
Starting 2 years after radiation therapy, the study staff will continue checking your
medical record to find out about your health status from then on.
This is an investigational study. IMRT is delivered using FDA-approved and commercially
available methods. IMPT is investigational.
Up to 60 participants will be enrolled in this study. All will be enrolled at MD Anderson.

Time to Cognitive Failure
Time to cognitive failure on any of 6 primary variables from pre-specified cognitive tests (HVLT-R total recall, HVLT-R delayed recall, HVLT-R delayed recognition, TMT Part A or Part B, COWA) with failure defined as a decline that meets or exceeds the reliable change index (RCI) for each cognitive test variable. A cumulative incidence approach used to estimate median time to cognitive failure in order to account for the competing risks of disease progression and death.
