Ben is an old friend of mine - he is an 18 year survivor of a gbm, and he wrote an excellent book about his thoughts on how to beat a GBM, called "Surviving Terminal Cancer: Clinical Trials, Drug Cocktails, and Other Treatments Your Oncologist Won't Tell You About". He writes a yearly update so that it is always fresh. This is the 2014 update, free for everyone. You can read it without reading the book, but the book is also valuable for the concepts.
