Analysis of survival after liver transplantation in Galicia, Spain

Transplantation is the treatment of choice for many patients with end-stage liver disease. We evaluated the results of liver transplantation in Galicia, an autonomous community in Northwest Spain.

We analyzed 452 patients and 490 grafts from 1996 to 2000 for causes of loss with respect to recipient and donor variables using the actuarial method, Kaplan-Meier curves, log-rank test, and Cox proportional risks model.

The overall graft survival was 77% and 64% at 1 and 5 years, respectively; while that of the patients was 83% and 69%. The risk factors for graft loss were donation in heart failure (HR = 4.91, CI:2.51-9.61); donor age (HR = 1.70, CI:1.01-2.85 between 40 and 60 years; HR = 2.37, CI:1.37-4.10 in those over 60 years, as compared to patients under 40); urgent transplant (HR = 3.95, CI:2.07-7.54); and transplant due to acute liver failure (HR = 3.53, CI:1.72-7.25) as compared to alcoholic cirrhosis. For patient death the risk factors were age of recipient over 60 years, compared to those under 40 (HR = 2.42, CI:1.11-5.28); foreign place of origin (HR = 2.02, CI:1.14-3.59); transplant due to viral cirrhosis (HR = 1.76, CI:1.03-3.02) and transplant due to acute liver failure (HR = 4.62, CI:2.12-10.06), as compared to alcoholic cirrhosis; urgent transplant (HR = 2.65, CI:1.48-4.72), and age of donor over 60 years, as compared to those under 40 (HR = 2.65, CI:1.48-4.72). Infections were the principal cause of death (45%), mostly in the first month (72%); while after the first year, 74% were due to recurrence of the primary disease and de novo malignancy.

Graft and patient survivals were comparable to international registries. The donor characteristics had a greater influence on graft survival than on patient survival.
