Novocure Announces the Publication of New Survival Data for Recurrent Glioblastoma Patients Treated with NovoTTF™ Therapy This is pretty impressive. According to the press release, this is the best reported results of any "non-experimental" treatment for recurrent glioblastomas. This reports on 457 patients, which is a very large number. The only experimental treatments that reported better results were in very small trials of about 10-20 patients and so far those results have never held up in larger trials.
