I asked that very question about my husband. I even asked why we don't just remove the whole pancreas and do a transplant there. The answer received was that pancreatic cancer is so aggressive that if there are mets to the liver, then there are likely mets to the lymph nodes and therefore there are likely more cancer cells in other parts of the body that have not shown up yet. It is not worthwhile to put the patient through the ordeal of a transplant (to say nothing of the risks to the donor) when the prognosis remains poor. It's a hard thing to hear, I know, but that's what we were told.
