Nick there are a lot of new treatments. If you are doing chemo I high suggest looking into ADAPT which is basically adding Celebrex to the chemo. It has shown some positive early results and is now going through trials. If anything it could buy yourself some serious time. The Celebrex seems to make the chemo a lot more affective.
I definitely would be taking at least Celebrex, if you don't have a contraindication for that (like heart problems, or tendency to strokes), during the next year. It's usually prescribed for arthritis and joint pain, so if you insist you have that, maybe...
