Overview
Brief Summary
This is a study to determine if Magnetic Resonance Imaging (MRI) techniques can detect early changes in white matter (in the brain) and the blood-brain barrier resulting from radiation therapy.
Detailed Description
Patients will be assigned to one of two groups based on the type of radiation they will be receiving: whole brain irradiation or partial brain irradiation. Patients will undergo Magnetic Resonance Imaging (MRI) assessments, neurocognitive testing (Quality of Life and Neuropsychological assessments), and clinical evaluation.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Patients receiving partial brain irradiation for malignant or benign brain tumors (including low-grade gliomas, high-grade gliomas, malignant meningioma, pituitary adenomas, supratentorial meningioma, or craniopharyngiomas); or patients receiving whole brain irradiation for brain metastases.
- •Patients must be 18 years of age or older
- •Patients must sign a study specific consent form approved by the Institutional Review Board (IRB) of the University of Michigan prior to study entry.
- •Patients must have a neurological function class 1 or 2 with a Karnofsky performance status (a scoring system used to quantify general well being and quality of life on a scale of 100 to 0) of greater than or equal to
- •Patients must have an expected life expectancy of greater than 6 months.
Exclusion Criteria
- •Patients with a history of major medical illness or psychiatric impairment which, in the investigator's opinion, will prevent administration of the protocol.
- •Patients who have had prior external beam irradiation to the brain or head/neck area that will lead to overlap of the radiation field.
- •Patients should have no contraindications to having a contrast enhanced Magnetic Resonance Imaging (MRI) scan.
- •Prisoners are excluded.
- •Pregnant women are excluded.
Outcomes
Primary Outcomes
Change in Magnetic Resonance Imagining (MRI) with different radiation dose at different timepoints.
Time Frame: Baseline, at 3 weeks on radiation therapy (RT) (partial brain irradiation only), last week of RT, 6 weeks post RT, 4 months post RT (whole brain irradiation only), 6 months post RT, 18 months post RT (partial brain irradiation only)
Linear mixed models will be used to relate Magnetic Resonance Imagining (MRI) changes and radiation dose.
Secondary Outcomes
- Associate changes in Magnetic Resonance Imagining (MRI) assessments with changes in neurocognitive function and clinical symptoms, from baseline, and at different timepoints.(Baseline, 6 weeks post radiation therapy (RT), 4 months post RT (whole brain irradiation only), 6 months post RT, 18 months post RT (partial brain irradiation only))
