BackgroundIn an effort to expand the donor pool for lung transplants, numerous studies have examined the use of advanced age donors with mixed results, including decreased survival among younger recipients. We evaluated the impact of the use of advanced age donors and single versus double lung transplantation on posttransplant survival.MethodsThe United Network for Organ Sharing database was retrospectively queried between January 2005 and June 2014 to identify lung transplant patients aged at least 18 years. Patients were stratified by recipient age 50 years or less, donor age 60 years or more, and single versus double lung transplantation. Overall survival was assessed using the Kaplan-Meier method. Multivariable survival analysis was performed using a Cox proportional hazards model.ResultsIn all, 14,222 lung transplants were performed during the study period. With univariate analysis, donor lungs aged 60 years or more were associated with slightly worse 5-year survival (44% versus 52%; p < 0.001). Among recipients aged more than 50 years, this trend was not present in the multivariate model (hazard ratio 1.23, p = 0.055). Among recipients aged 50 years or more, receiving older donor lungs showed worse survival with the use of single lung transplant (5-year survival 15% versus 50%, p = 0.01). No significant difference in survival between young and old donors was seen when double lung transplant was performed (p = 0.491). Cox proportional hazards model showed a trend toward interaction between single lung transplantation and older donors (hazard ratio 2.36, p = 0.057).ConclusionsReasonable posttransplant outcomes can be achieved with use of advanced age donors in all recipient groups. Double lung transplantation should be performed when older donors (age more than 60) are used in young recipients (age 50 or less).Copyright © 2018 The Society of Thoracic Surgeons.
