This was done on cells in a lab, not in people. It is a very early step.
This was only done on cells and tissue slices in a lab, not in people.
The short version
Scientists made a drug that, when hit with light, killed glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary cells in lab tissue.
What was studied. Researchers built and tested a group of new light sensitive drugs. They tried them on glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary cells from patients, on mouse brain slices, and on tissue from people with brain cancer.
What they found. One drug, called Gal-SeNBD-oleamide, was taken up well by glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary cells from patients. It went into the cancer cells more than into immune cells. When the mouse brain slices were lit up, the cancer cells died and nearby areas had little damage.
What this means, and what it doesn't
What it could mean: Light based therapy may someday help clear tumor cells left behind after surgery. This work is an early step toward testing that idea.
What it doesn't mean: This is not a treatment you can get now. The work was done on cells and on slices of brain tissue in a lab. No patient was treated with it. It does not show that people live longer or feel better. It is not a cure.
