I am sorry to hear this but want you to know there is hope with treatment!
I see that others have given you links where you can find more information. Just wanted to share one of YHR's fosters with you. Little Roriee came to us in terrible shape from GME and is a little miracle now after having undergone chemotherapy. You can see her story at:
Adoptable Pups
We also have a thread about her on YT at:

So, there are successful stories out there! Keep positive thoughts!
You and Carson will be in my thoughts and prayers.
