Hello Gstaton
My dad was diagnosed with GBM on 5/1/2011 in his speech center on the left side (worst place for GBM). 55% resection, 6 weeks radiation, and 5 cycles of temodar. Was tapering down dexamethazone and was at 2mg daily as of four days ago.
We found that if you want him to have every month on earth you can then go for radiation. In our opinion though we wish we wouldn't have because we would rather shoot for long term survival. Radiation necrosis has caused all sorts of problems for Dad since his treatment.
We had some scary MRIs in the months following initial treatment. Since starting a restricted calorie ketogenic diet 15 months ago every MRI has been stable and sometimes it even gets a bit smaller.
We find the ketogenic diet works great for our family and we've adapted our family meals to work with it. It is a BIG commitment. Usually, if a cure sounds too good to be true, it is. This maintenance regimen is tough, but the only sure fire bet to prevent brain tumor growth IMO based on research I've done from multiple continents. Dad has been thriving on it- despite wishing to recover from the deficits caused by radiation and surgery (speech and balance).
We've talked with countless doctors, considered dozens of immuno therapy treatments, but this has been working for us.
That said, we were trying to get off steroids completely and just had a scare this week and are waiting for MRI results. This has happened before when we tried to get off them. The MRI indicated necrosis based on a profusion study, and I’d guess that's what it will be, but wanted to tell you of the scares as well so you get the full picture. This diet MAY be working as a maintenance plan, or we might just be lucky. The research suggests it must work.
My word of caution is that you should be careful what treatment you do now because it will affect your long term quality of life. Fortunately his tumor is in a MUCH better spot that should cause much less neurological deficits.
