The influence of posttransplant lymphoproliferative disease (PTLD) on long-term survival after heart transplantation (HTx) in adult recipients needs better characterization.MethodsThe United Network for Organ Sharing database was queried from 2006 to 2015 to compare survival between adult HTx recipients with and without PTLD. Cox proportional hazards models were used to analyze the primary outcome of survival, and competing-risks regression was used to analyze the outcome of PTLD development.ResultsA total of 14,487 HTx recipients who had data on PTLD were included in univariate Cox analysis and Kaplan–Meier survival function, while 10,422 were included in multivariable Cox analysis and 162 selected for a matched-pairs sample after matching on the propensity of developing PTLD. The cohort included 120 patients who were diagnosed with PTLD. Onset of PTLD, treated as a time-varying covariate, was adversely associated with survival in univariate (HR = 4.953; 95% CI: 3.768, 6.511; p < 0.001) and multivariable (HR = 3.849; 95% CI: 2.669, 5.552; p < 0.001) Cox proportional hazards models. Cox regression stratified on matched pairs of PTLD cases and non-PTLD controls confirmed the risk for death associated with PTLD onset (HR = 2.667; 95% CI: 1.043, 6.815; p = 0.040).ConclusionsPTLD onset negatively influenced survival in adult HTx recipients, whereas no characteristics predisposing patients to PTLD development were identified in multivariate analysis.
