Intervention / Treatment
Detailed Description
An initial 15 patients will be enrolled in the first treatment scheme (5 daily fractions of 2 Gy) and will be followed for 12 months after completion of treatment to assess safety and any toxicity/adverse events associated with treatment. In Arm 1 the 15 study participants will be enrolled in total at Botsford Radiation Oncology Center and William Beaumont Hospital (Royal Oak Campus). Once a total combined 15 patients are entered this Arm will be closed.
The second treatment arm will not be used until the last patient in the first dose arm has completed all follow up. At that point patients #16-30 will be enrolled in the second dose arm (10 daily fractions of 2 Gy). In Arm 2 the 15 study participants will be enrolled in total at both Botsford Hospital Radiation Oncology Center and William Beaumont Hospital (Royal Oak Campus). Once a total combined 15 patients are entered this Arm will be closed.
A total of 30 patients will be enrolled and each will be followed for 12 months to assess safety and toxicity/adverse events.

Florbetaben F 18 Injection (AMYVID) Positron Emission Tomography (PET) Scan: Change From Baseline to 4 Months in Standardized Uptake Value Ratio (SUVr) for Frontal Region of the Brain Compared to Cerebellum
Time Frame: Baseline to 4 months post-treatment
|
SUVr is a measure of the amount of radiotracer activity bound to beta amyloid plaque in an individual region of brain tissue compared to radiotracer activity in the cerebellum, which is rarely involved by neuritic plaques.
An elevated ratio >1.10 indicates a strong likelihood of significant underlying neuritic plaque burden.
The percent change from baseline to 4-month scans in the frontal region is reported (percent change is calculated by subtracting baseline value from 4-month value; the result is then divided by the baseline value and multiplied by 100 to give a percentage).
A positive number (percentage) indicates an increase in SUVr and more plaque burden in the frontal region, while a negative number (percentage) indicates a decrease in SUVr and a reduction in plaque burden in the frontal region.
