This was tested in people. That is the most reliable kind of research we share.
This study looked back at records from real patients. It did not test a new treatment.
The short version
People with glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary who lived in rural areas got key treatments less often.
What was studied. Researchers looked at records for 10,041 people with glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary in a large US cancer database. They compared people who lived in rural areas with people who lived in cities.
What they found. Rural patients were less likely to get surgery, radiation, or chemotherapy. After the two groups were matched for other differences, rural patients had a higher risk of dying from their cancer. The gap was smaller for people diagnosed from 2010 to 2019 than for people diagnosed from 2000 to 2009.
What this means, and what it doesn't
What it could mean: Where a person lives may shape the care they are offered. If you live far from a cancer center, it can help to ask your team about surgery, radiation, and chemotherapy. Ask what is possible for you and what help is out there to reach it.
What it doesn't mean: This does not mean that living in a rural area causes a worse outcome. The study only looked back at records that were already collected. It cannot prove what caused the difference. It did not test any new treatment, so this is not a cure or a new option to ask for. Many people in rural areas do get full treatment. A second group of patients at one hospital showed a similar trend, but the result was not clear enough to be sure.
