Liver Living Donation for Cancer Patients: Benefits, Risks, Justification.

Abstract

LDLT covers all standard indications for liver transplantation, and the results are similar or even better than for standard DDLT. Due to the donor shortage and long waiting time, LDLT has become a relevant option for patients with liver tumors, provided the expected five-year survival rate is comparable to that of patients receiving a DDLT. Nowadays, LDLT offers the possibility to extend the standard morphometric selection by considering the biological parameters. In the setting of LDLT, we are not only faced with surgical morbidity in the donor, but long-term non-medical problems like psychological complications and financial burden also have to be considered. On the other hand, the benefits to the donor are mainly social and psychological. In LDLT, the donor's altruism is the fundamental ethical principle and it is based on the principles of (1) beneficence (doing good), (2) non-maleficence (avoiding harm), (3) respect for autonomy, and (4) respect for justice (promoting fairness). On top of that, the concept of double equipoise of living organ donation evaluates the relationship between the recipient's need, the donor's risk, and the recipient's outcome. It considers each donor-recipient pair as a unit, analyzing whether the specific recipient's benefit justifies the specific donor's risk in particular oncologic indications. In this light, it is essential to seek adequate informed consent focused on risk, benefits and outcome benefits of both donor and recipient supported by an independent living donor advocate. Finally, the transplant team must protect donors from donation if harm does not justify the expected benefit to the recipient.
