HI there, I am new to this site, my husband has a GMB 4 also, after his operation on july 12 last year, his was the size of a closed fist, we were told treatment wouldn't help, but we had the 6 weeks chemo/radiation, then triple dose chemo tablets for 5 months, first scan in dec was good, scan in feb showed 4 tumors, they have sent us home, no more treatment, he is 57, but i suppose that the size of the first one was the problem. he is doing well, minus one set back a couple of weeks ago, minor stroke which caused a mayor seizure, but in true form has bounced back just great, go figure, take care everyone, hope you all make it.
