My wife ws diagnosed with GBM IV in August of 2004. Radiation and Temodar were not effective. She tried several therapies which did not work or worked for a short time. Duke started her on Avastin and CPT 11 in June 2005. It also worked for about 3 months.
She passed away in October of 2005, 15 months after the diagnosis. Everyone's experience is different.
I wish you and your father well.
