This is a new way to treat brain tumors. The patient drinks a dye - they did not say which one but it sounds like Gleolan - which binds to the tumor. Gleolan is fda approved to be used during surgery to help the surgeon tell the difference between tumor and normal brain. They then use focused ultrasound to treat the brain, and kills the tumor cells which have taken up the dye. Sounds like a good plan! They will have the first in human trial starting soon! I wish them luck. Kudos to the National Brain Tumor Foundation and American Cancer Society for funding it!
