Ok @LMK74 we need to define 'failed'. I'm with @primek This is a shit of a disease and there are absolutely no guarantees that any of the treatments will work as well as hoped but there is a chance, albeit slim, that you haven't completely wasted your time and that the chemo that didn't shrink your tumor may have helped check the progression of your cancer.
You know, I reckon one of the nice things about this site is everyone tries to be nice but sometimes someone needs to say it. Fuck, fuck, fuckity fuck. My apologies to anyone that may be offended. Margxxxx
