Abstract

Post-transplant lymphoproliferative disorder (PTLD) has been associated with high mortality, but recent anecdotal survival appeared better. From 1988 to 2010, the NAPRTCS registry had 235 registered PTLD cases. We sent a special 25-point questionnaire study to the NAPRTCS centers with the most recent 150 cases to obtain additional follow-up data not collected in the master registry, our objective being to determine the recent outcomes after PTLD and determine prognostic factors. We received 92 completed responses, in which only 12 (13%) deaths were reported, 2 from nonmedical causes, 10 with a functioning graft. Kaplan-Meier-calculated patient survival was 90.6% at 1 year and 87.4% at 3, 4 and 5 years post-PTLD. Graft survival post-PTLD was 81.8% at 1 year, 68.0% at 3 years and 65.0% at 5 years. Seven patients received a retransplant after PTLD, with no PTLD recurrence reported. Using all 235 PTLD cases, the covariates associated with better patient survival were more recent year of PTLD diagnosis (adjusted hazard ratio AHR 0.86, p < 0.001), and with worse survival were late PTLD (AHR 1.98, p = 0.0176) and patient age above 13 at PTLD (AHR 3.43, p value 0.022). In children with kidney transplants, patient survival has improved with more recent PTLDs.
