Hi Debralynn.
It seems that most medical professionals recommend the radiation and Temodar as the first line of treatment. I believe that is because it does work for some patients and it is more easily tolerated by the patient. No need to go on the really aggressive, heavy duty stuff if the Temodar works well.
Radiation and Temodar did nothing for my husband and in fact, the post radiation MRI showed tumor progression. They abandoned the plan to put him on the higher dose Temodar and switched to Avastin / CPT-11. So far, so good. We're at 1 year and 17 days after diagnosis.
I haven't read Dr. Arenson's website but I'll bet Lorre G can tell you why he chooses to use a more aggressive treatment and she should also be able to tell us all if it seems to work better than the less heavy duty approach.
Best wishes,
Barb
