I was diagnosed with GBM in April 2017 and given a 2 year life expectancy. I had a crainiotomy and the standard of care - radiation and temodar and now on the maintenance temodar of 5 days every 28 days. I have just completed month 15 of that plan. I will be on it for 2 years. My main complaint is the headaches. I have them 24/7 with some days being more severe than others. MRI every 3 months with no sign of reoccurence.
