As you learn about liver cancer treatment, embolization and resection usually come up first, but at a certain point a transplant enters the conversation. Rather than cutting away part of the liver, it removes the entire diseased liver and replaces it with a new one. What sets it apart is that it does not just eliminate the tumor; it overturns the very ground the tumor grew in, the damaged liver itself.
The classic situation for considering a transplant is when liver cancer develops in someone whose liver function is already badly reduced by severe cirrhosis. With such a liver, removing part of it would leave too little behind to keep working. A transplant, on the other hand, solves the tumor and the failing liver at the same time, so it can actually open a path for patients whose poor liver function made surgery difficult.
Even so, it is not recommended for everyone. Because a limited number of livers must be allocated, eligibility is set by the range within which a transplant can be expected to give good results. The commonly used Milan criteria look for a single tumor of 5 cm or less, or up to three tumors each 3 cm or less, with no blood vessel invasion and no spread to other organs. Only those who fall within this range are evaluated as transplant candidates.
A liver comes from one of two sources. One is receiving the liver of a brain-dead donor; the other is living-donor liver transplantation, in which a family member or another living person gives part of their own liver. In countries where deceased donation is scarce, living-donor transplants make up a large share. Since the donor also undergoes surgery, tests are carried out alongside to weigh the donor's safety and suitability.
The waiting period is the part that frays the nerves most. If you are waiting for a deceased donor, there is no telling when your turn will come, and if the tumor grows beyond the criteria in the meantime, you can be pushed off the candidate list. So during the wait, treatments such as embolization are sometimes used as a bridge to keep the tumor from growing further. A living-donor transplant has an advantage here, since the timing can be set once a suitable donor is found.
A liver transplant is clearly a treatment that takes a major decision, but when it fits well, it can clear both the cancer and the cirrhosis in one stroke and lead to a long, stable life. Whether your liver and tumor fall within the criteria, and whether a living or deceased donor is the realistic option, is something to weigh thoroughly with a transplant team first.
