I have to say I'm very, very wondered about these outcomes! We've discussed this with surgeons but they said it was a no go. Main reasons being that the cancer is likely to spread to other organs and because of the transplant the immune system has to be surpressed so the liver won't be rejected (or something like that..) so the disease can also return in the new liver.
There is a shortage of donors, but living donors can also be used. If I can give my father a couple extra years I'd be happy to have a part of my liver transplanted. I know however it's not that simple.
Here is also something worth reading about it (all recent reports, some related to each other):
