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 lab dish, not in people.
The short version
Some chemicals from plants killed brain tumor cells in a lab dish, while doing much less harm to normal skin cells.
What was studied. Researchers tested plant chemicals called terpenoids. They were alpha-pinene, farnesene, carvone, and terpinolene. Each one was put on human glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary cells growing in a dish. They were also put on normal human skin cells, to see if the effect was picky about which cells it harmed.
What they found. The terpenoids killed more tumor cells as the dose went up. They were much less toxic to the normal skin cells. At 30 micrograms per milliliter, all of them raised a sign that the tumor cells were shutting themselves down. They also shifted the balance of oxidants in the tumor cells, raising the protective side and lowering the damaging side.
What this means, and what it doesn't
What it could mean: This points to a few plant chemicals that may be worth more study for glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary. It does not change any care you or your doctor can give today. The authors say the next step is more lab work to learn how these chemicals act.
What it doesn't mean: This does not mean a new treatment is coming. The work was done on cells in a dish. It was not done in people, and it was not even done in animals. No patient was treated and no patient got better. This is not a cure and it is not a promise of one. Many things that kill tumor cells in a dish never help people.
