I want to offer a differing opinion. It's not me who has the cancer - it's Sailorman (Will) and I've said the same thing to him too and he didn't like it either. So most of you are probably not going to like this. I think, if you have a pretty good idea that the cancer is bad and you're not going to live very long, you should concentrate on enjoying your life and not torture yourself with further chemo treatments. I know chemo is very difficult. I've seen it with two people - my father and a friend - and if they had foregone the chemo towards the end, they would have been able to enjoy more (and possibly even live longer). There's also an old book, "The Cancer Ward," written by Aleksandr Solzhenitsyn (Russian), which is autobiographical. In it he undergoes all sorts of treatments that are so horrible he eventually walks out of the hospital, abandoning his treatment. In real life, he moved to the U.S. where he lived out the rest of his long live in Vermont. He walked out and the cancer didn't come back.
Out tendency is to do whatever the doctor says and to keep trying things that may work. That would be fine if the treatments were painless, but they're not. They're hard and they destroy your quality of life. That's my 2 cents, for what its worth. Live and have fun.
