This was done on cells in a lab, not in people. It is a very early step.
This was only done on cells in a dish.
The short version
In lab dishes, a compound called arvanil killed the tumor cells that are hardest to treat.
What was studied. Researchers tested capsaicin and similar compounds on glioma: A tumor that starts in the glial cells. Those are the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4. The grade says how the tumor is expected to act. See the glossary stem cells. These are glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary cells that resist radiation and chemo and help the tumor come back.
What they found. One of the compounds, arvanil, killed glioma: A tumor that starts in the glial cells. Those are the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4. The grade says how the tumor is expected to act. See the glossary stem cells. It did this at doses that did not harm normal cells. The dying cells built up harmful forms of oxygen inside them, and blocking calcium stopped the killing.
What this means, and what it doesn't
What it could mean: It points to a possible weak spot in the cells that make glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary return. Scientists now have a target they can keep studying.
What it doesn't mean: This does not mean a new treatment exists. The work was done on cells in a dish, not in animals and not in people. Arvanil is not a drug you can get, and it is not a cure. Years of more testing would be needed before anyone knows if it helps patients.
