Researchers have identified immune genes that may affect how long people live after diagnosis with a common type of brain cancer.
If confirmed in other studies, the researchers say their findings could lead to improved treatment in the future.
The type of brain cancer in the study is glioblastoma multiforme, a fast-growing tumor. People with this type of cancer survive an average of less than two years, even after treatment with surgery, radiation and chemotherapy, the study authors said.
