what I know

a few glioma patients (adult) I know of responded well to avastin with good result - extended survival, but majority did not. I don't know about pediatric cases. 9x15x22 is a big tumor and glioma tend to grow quick, my guess his best hope is radiation at this point if no effective systemic therapy is found. You can qqh or p.m. me (636 686 0275 text only) if you want to discuss more experimental therapies in GBM. I've lost 2 friends to this disease in the last couple of year.
