This was done in animals, not people. Most findings at this stage never become treatments.
This was only done in mice and in lab dishes.
The short version
Scientists built a large set of lab models to learn how 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 spreads in the brain.
What was studied. Researchers grew 65 cell cultures taken from the tumors of people with 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. They placed these cells into the brains of 449 mice and watched how each tumor grew and spread.
What they found. The tumors spread in two main ways. Some spread out widely through brain tissue, and others grew in tight clumps around blood vessels. The team also found 15 molecular patterns in the tumors, and two drugs, PIK-75 and buparlisib, slowed spreading in lab tests.
What this means, and what it doesn't
What it could mean: This gives researchers better tools to test new drugs for 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. It also points to two drugs that may be worth more study. It does not change care for anyone today.
What it doesn't mean: This is early lab work. The tests were done in mice, in dishes, and in slices of brain tissue. No person was treated in this study. The two drugs are not approved for brain tumors. This is not a cure, and it is not a promise of one. It is a long way from everyday care.
