Abstract
Post-Transplant Lymphoproliferative Disorders (PTLD) are heterogenous lymphoproliferative disorders that develop as a consequence of immunosuppression in transplant recipients. We performed a retrospective review of PTLD occurring in pediatric heart transplant recipients. A total of 558 children and infants underwent cardiac transplantation at our institution between 1985 and 2019 were followed until March 2021. Forty-nine of 558 patients developed PTLD (8.8%). As compared to older children (>1 year of age), infant recipients (<3 months of age) were less likely to develop PTLD. Monomorphic PTLDs (M-PTLD, 61%) was the most common subtype at initial diagnosis, followed by non-destructive (21%), polymorphic (14%), and classic Hodgkin lymphoma (cHL, 4%). Patients who underwent transplantation at a young age (<3 months) had significantly lower rates of M-PTLD or cHL, and longer time from transplant to PTLD diagnosis as compared to children older than 1 year at transplant (p=0.04). Tthose patients with a shorter time to PTLD diagnosis showed a trend toward a higher rate of M-PTLD or cHL. As expected, the overall survival (OS) of patients with M-PTLD or cHL was significantly lower than patients with non-destructive or polymorphic PTLD.
