Risk factors predicting survival of liver transplantation.

ABSTRACT

Prognostic models were developed for analyzing graft survival in a single-center study consisting of all 388 adult liver transplantations performed during 20 years. Proportional hazard models and generalized linear models were used to assess which risk factors, related to donor and recipient characteristics as well as graft preservation and operation, had an effect on graft survival. The prognostic modeling evidenced favorable trends in graft survival time during the successive quinquennials 1982-1987, 1988-1992, and 1993-1997, in comparison to the referent time period 1998-2002. Significant predictors of graft survival time were donor's age, recipient-donor gender compatibility, recipient's blood group, intraoperative blood transfusion, size of the transplanted organ, and indication for transplantation. Conventional histocompatibility matching did not correlate with graft outcome.
