Poliovirus treatment for glioblastoma posts 'encouraging' survival data, but work remains

Duke University's poliovirus-based glioblastoma treatment burst on the scene in 2015, thanks to the CBS show "60 Minutes." At the time, only a few patients had received the treatment, and it was unclear if a virus would even work against brain tumors. Now, the scientists behind it are reporting an "encouraging" long-term survival rate in patients with recurrent glioblastoma.
