I have a friend who was diagnosed with an astrocytoma grade 2, in late April. They are treating her with chemo. She has had about 4 rounds of it. It has not grown which we know is good, but it has not shrunk after her MD has tripled her dose the last round. The pet scan shows no change. Her MD states her tumor is diffuse throughout her brain and is inoperable. The plan is to do 2 more rounds of chemo, then another pet scan> She is going to UAB hospital for RX. I know each case is very unique, but I was wondering is this somewhat typical of this type of brain tumor? Thank you for your answering my question & it is strictly confidential.
