What is the real gain after liver transplantation?

1. For most liver allograft recipients, both the quality and length of life are greatly improved after transplantation. However, neither the quality of life nor the length of life in the survivors returns to that seen in age-matched and sex-matched normal subjects. 2. The gain in survival after transplantation can be estimated by a comparison of the actual outcome after transplantation and the predicted survival in the absence of transplantation. 3. The reduction in graft and patient survival, in comparison with a normal age-matched and sex-matched population, is determined by several factors: short-term survival is affected by the patient's condition pre-transplant and the quality of the graft, and for longer term survival, recurrent disease accounts for most of the differences seen between different indications. Some of the causes of premature death (such as infection, de novo malignancy, and cardiovascular and cerebrovascular disease) that are increased in the liver allograft recipient may be reduced by improved management with more aggressive surveillance and treatment. 4. The aims of selection and allocation vary in different health care systems: transparency, objectivity, equity of access, justice, mortality awaiting transplantation, utility, and transplant benefit are all important but often competing demands. Understanding the associated increase in survival will allow for a rational approach to this complex area. (c) 2009 AASLD.
