Comparative survival of elderly renal transplant recipients with a living donor versus a deceased donor: A retrospective single center observational study.

Abstract

SummaryIncreasing numbers of elderly (≥65 years) patients are listed for kidney transplantation. This study compares the survival outcome between living (LDK), regularly allocated (ETKAS), and Eurotransplant Senior Program (ESP) donor kidneys in elderly recipients. This is a single‐center retrospective cohort study of elderly kidney transplant recipients transplanted between 2005 and 2017. Primary outcome measures were nondeath‐censored graft, death‐censored graft, and patient survival. In total, 348 patients were transplanted, 109 recipients (31.3%) received an LDK, 100 (28.7%) an ETKAS, and 139 (40%) an ESP kidney. 62.5% were male, and median age was 68 years. LDK recipients had significantly better 5‐year nondeath‐censored graft survival compared with ETKAS and ESP (resp. 71.0% vs. 66.1% vs. 55.6%, P = 0.047). Death‐censored graft survival after 1 year was significantly better in LDK recipients (99.1%) (ETKAS 90.8%; ESP 87.7%, P < 0.001). After 5 years, the difference remained significant (P < 0.001) with little additional graft loss (97.7% vs. 88.1% vs. 85.6). There was no significant difference in patient survival after 5 years (71.7% vs. 67.4% vs 61.9%, P = 0.480). In elderly recipients, the patient survival benefits of an LDK are limited, but there is decreased death‐censored graft loss for LDK recipients. Nevertheless, graft survival in ETKAS and ESP remains satisfactory.
