If you haven't already, I would seek a second opinion at a top hospital if you are in the US. You can find them at

In July of '04, I was told I had 18 months to live with treatment, but that I could die at any moment. I went to the U of Minnesota and got a lot better odds. I have been NED since September '05.
I know of two other people who finally got other opinions at good hospitals and now have been told they can be cured. StageIVartist is one.
Good luck.
