Shawn,
As a survivor, recurrence is our biggest and most feared nemesis. I can't even begin to imagine what it's like to hear the word "terminal". I do agree with the previous post in gathering your information and seeking a second opinion. Perhaps there's a trial that would fit your situation. I know of warriors that are doing well and prolonging their lives with excellent quality of living so it's certainly worth a look see.
In the mean time, my thoughts and prayers are with you. You're a brave soul and warrior. Continue the battle!
