MULTISTATE MODELING OF LIVER-TRANSPLANTATION DATA

This paper concerns the survival analysis of liver transplant patients when patients with a potentially fatal rejection of the transplanted organ may receive a retransplant, A multistate model, analysing the states 'alive with first graft' and 'alive with second graft' separately, is suggested. Proportional hazards models and logistic regression models are used to evaluate which risk factors related to donor, preservation and recipient, influence the transition intensities. The complete model is used to predict overall survival of a patient and to study the influence of the risk factors on total survival.
