This was done on cells in a lab, not in people. It is a very early step.
This was only done with cells in a dish, not in people.
The short version
In a lab test, an electric field killed glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary cells but left normal cells alone.
What was studied. Scientists tested an electric field therapy called ECCT on cells in a dish. They used two kinds of human glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary cells and one kind of normal cell.
What they found. Fewer glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary cells stayed alive after the electric field, set at 100 kHz and 20 V. One kind, U87-MG, dropped at every exposure time. The other kind, T98-G, dropped clearly only after 24 hours, and the normal cells kept their shape and stayed alive.
What this means, and what it doesn't
What it could mean: This is an early hint that electric fields may harm tumor cells. It may also leave healthy cells alone. No one can get this as a treatment today.
What it doesn't mean: This was done only with cells in a dish. It was not tested in people, or even in animals. It does not show that anyone lived longer or felt better. It is not a cure, and it is a long way from the care you get now. Much more testing has to come first.
