Abstract
Post-transplant lymphoproliferative disorder (PTLD) is a well-known complication of hematopoietic stem cell transplant and solid organ transplant. While reduction in immunosuppression (RIS) is the first-line treatment for PTLD, outcomes of allograft function as a result of RIS remain understudied. In this retrospective study, we examine rates of allograft rejection and graft failure after RIS in 141 patients diagnosed with PTLD at the University of Florida. Compared to prior literature demonstrating around 32–40% rate of allograft rejection as result of RIS, our institutional analysis revealed a much lower treatment-related allograft rejection rate of 18.4%. Out of the patients who experienced acute allograft rejection, 23.1% ultimately progressed to allograft failure. Interestingly, acute allograft rejection episodes during PTLD treatment were not statistically found to impact overall survival. RIS remains an overall beneficial treatment modality of PTLD due to its low allograft rejection rate relative to treatment rate. [ABSTRACT FROM AUTHOR]
