The latest news: New Trial: Phase I/II Trial of Repeated Superselective Intraarterial Cerebral Infusion of Bevacizumab (Avastin) for Treatment of Newly Diagnosed Glioblastoma Multiforme This is one of my favorite neurosurgeons.. when I first heard about him using Avastin in the way, I thought it was crazy, but after having him explain the thinking behind it, it makes a lot of sense. I videotaped his explanation - go to www.virtualtrials.com/video2012.cfm for the video. This might be a better way to use Avastin.
