Detailed Description
The Study Procedures:
MRI scanning is commonly used to check the status of glioblastoma. In this study, MRI scanning will also be used to try to better understand how chemotherapy that blocks blood vessel growth may be affecting the status of the glioblastoma.
The timing of all MRI scans for this study will be done on schedule for routine patient care. There will not be any extra MRI scans performed, but an MRS portion to the MRI scans will be added. The MRS results will be used in this study to look at the chemical differences between the cancerous and normal tissue, in order to try to better understand how your chemotherapy may be working.
Screening Tests:
Before you can begin this study, you will have "screening tests" to help the doctor decide if you are eligible to take part in this study. The following tests and procedures will be performed:
- Blood (about 1 teaspoon) will be drawn for routine tests.
- Women who are able to have children must have a negative blood (about 1 teaspoon) pregnancy test.
MRI/MRS Scanning:
If you are found to be eligible to take part in this study, you will have an MRI/MRS scan of the brain. The first of these scans will be performed before the chemotherapy starts (either before your first cycle of this type of chemotherapy or before your next cycle, depending on whether you were receiving this type of chemotherapy before the study or not). After that, an MRI/MRS scan will be repeated at Weeks 8 and 16 after the beginning of chemotherapy.
The MRI/MRS scans will follow the same procedure and use the same MRI scanner machine as a regular MRI scan, but will take about an additional 10 minutes. You will lie still on your back with your head placed within the openings of the scanner. A contrast solution, which helps make the tumor visible, will be given through a needle in your vein. The scanning procedure should take about an hour at each visit.
The results of the MRI/MRS scans will not be used to affect your course of treatment.
Tissue Collection:
If your regular doctor recommends that the tumor be surgically removed, the surgery will be discussed with you in detail and you will sign a separate informed consent form for it. Leftover tissue that was removed during the surgery will be collected and used as part of this study. The tissue will be used to further check the status of the disease, and it will be compared with the MRI/MRS images.
Biomarker Testing:
In this study, you will also have blood drawn for biomarker testing. Biomarkers are chemical "markers" in the blood, other body fluids, or tissue that may be related to the status of disease and/or the effects of treatment. This blood (about 2 teaspoons each time) will be drawn before the chemotherapy starts and then every 8 weeks while you are on study. The blood draws will occur on the same days as the MRI/MRS scanning.
Length of Study Participation:
You will continue having blood drawn for biomarker testing every 8 weeks, unless you stop taking this type of chemotherapy that blocks blood vessel growth. In that case, you will be taken off study.
If you do have surgery, your participation in this study will end after the surgery. If you are unable to have surgery, your participation will end after your last MRI/MRS scan.
This is an investigational study. MRI scanning is an FDA approved and commercially available procedure for checking the status of glioblastoma. At this time and for this purpose, MRS scanning is being used in research only.
Up to 18 patients will take part in this study. All will be enrolled at M. D. Anderson.

Description
Inclusion Criteria:
- Patients with histologically proven intracranial glioblastoma or gliosarcoma will be eligible for this protocol
- Patients with recurrent glioblastoma or gliosarcoma who are scheduled to start systemic chemotherapy with bevacizumab.
- Patients tumor must be located in an area that is amenable to the proposed imaging sequences.
- Patients must be age 18 or older.
- Karnofsky Performance Status Scale (KPS) >/= 70.
