This was done on cells in a lab, not in people. It is a very early step.
This was only done with cells grown in the lab, not in people.
The short version
In the lab, tumor cells that clumped together in certain ways were the more aggressive ones, and blocking the glue between them made chemotherapy work better.
What was studied. Researchers grew human neuroblastoma cells and 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 taken from patients in small rounded wells in the lab. They watched what shapes the cells formed and which sticky proteins they used to hold on to each other.
What they found. The shapes matched how aggressive the cells were. Gentler cells spread out in flat layers, malignant cells formed tight balls, and the most invasive, stem-like cells formed uneven clumps. The aggressive cells had high levels of a sticky protein called N-cadherin. A drug called ADH-1 blocks that protein, and it broke the clumps apart. When ADH-1 was given with the chemotherapy drug DOX, the two together killed more of the aggressive cells than either did on its own.
What this means, and what it doesn't
What it could mean: This gives researchers a simple way to grow tumor cells in the lab and see how aggressive they are. It also points to the glue between tumor cells as something future treatments might target. In time, this kind of test might help doctors pick drugs for one person's tumor.
What it doesn't mean: This does not mean there is a new treatment. All of this was done with cells in a dish, not in people. Nobody was treated and nobody got better. Cells in a dish often behave differently than a tumor in a person. This is early lab work, and it is not a cure or a promise of one. It is many years and many studies away from anything your doctor could offer you.
