Hello Everyone, I am an older sister of a 25yr old brother who was diagnosed with GBM in March,2012. He had lost most of his site due to where the tumor was and has done all 3 treatments (Surgery x 2, radiation and chemo). Last week he found out the tumor has come back in a different part of the brain and it's to deep to operate on. He cannot do radiation again due to the risk of damage to the brain. Our options are clinical trial with a new drug called LY2157299,chemo or Avastin. I also read something about a DCA drug that was shown to reduce tumor in mice. Has anyone heard or tried this drug? We are undecided about what treatment to do but need to make a decision quickly. Thank you ... View more
