UCLA discovery will aid in treatment of patients with a deadly brain cancer

... those lethal forms of cancer. "In a biologically aggressive disease like glioblastoma, it's vital to be able to stratify patients up front so we can treat them with drugs that they are more likely to respond to," Mischel said. "This will help prevent patients from having therapies that are much more toxic and...
