My brother was diagnosed w/GBM on 1/18/00. He has just been told that the tumor has grown significantly even though he has finished 34 stereotactic radiation & 5 of 6 chemo following. He and his wife told us they will not continue further treatment. What can I expect this disease to do to him in the following months? Is there some treatment that will convince him to return to his drs? He has been treated by CINN in Chgo. As family & friends we felt that was the best. Now we are very frustrated but truly trying to understand. Any information, links to GBM sites, etc. would be appreciated. Thank you. Pat Meekma
