Dan,
I am so sorry for your loss-my heart goes out to you. I lost my father this past Saturday, April 26th to GBM. It was a terrible experience and I can't get the images of him dying right in front of me out of my mind. He was diagnosed in 2003, had surgery, radiation, and countless rounds of chemo....we were on a roller coaster ride for almost 5 years. He got pneumonia and pulmonary emboli last fall and never really recovered after that. He started Avastin, which caused major brain damage to his healthy brain, while shrinking his tumor (ironically). He declined so fast overnight that we were all shocked and thought it was tumor regrowth for sure. His entire brain was inflammed with many dead areas from the Avastin. This is the risk you take to treat this horrible disease. It was absolutely dreadful to watch my father lose not only his body, but his great mind. He literally withered up, became incontinent, couldn't walk, etc. overnight. It is hard remembering him like that. I do believe he knew we were all at his side while he passed, which gives me some comfort. My prayers are with you.
