Liver transplant for the septuagenarians: Importance of patient selection

With the increasing success of liver transplantation (OLT), more patients above 70 years of age are being considered for OLT. There is not enough data about the predictors for survival in this patient population. We retrospectively analyzed the medical records of 33 patients at least 70 years of age who received 34 OLT from July 1995 to July 2002. There were 16 women and 17 men of mean age 73.7 years. Etiologies of end-stage liver disease (ESLD) were: HCV (17/33, 52%), cryptogenic cirrhosis (8/33, 24%), PBC (3/33, 9%), Laennec's cirrhosis (2/33, 6%), and others (3/33, 9%). According to the UNOS classification, 15/34 (44%) were status 3, 16/34 (47%) status 2, and 3/34 (9%) status 1. Among 13/33 patients who died (39%), 1-year and 3-year survival rates were 78.79% and 71.43%, respectively. Based on UNOS criteria, 4/15 (26%) were status 3; 6/16 (37%), status 2; and 3/3 (100%), status 1 (P value = .04 for status 1 patients). There was no statistical differences between the scores using the Model for End-Stage Liver Disease (MELD) among those who died (MELD (19) versus MELD (17.35) respectively (P = .50). There was a statistically significant difference in cold ischemia time (CIT) and warm ischemia time (WIT) between those who died (P = .024 and .010, respectively). These results suggest that in this group of patients UNOS status classification, CIT and WIT correlate with survival. The sample size was too small to derive a conclusion about the association with the MELD score.
