Abstract
BACKGROUND
Post-transplant lymphoproliferative disorders (PTLD) are a complication of chronic immunosuppressive therapy in solid organ transplantation with a high mortality rate. Alternative treatments such as rapamycin have been explored.
METHODS
A detailed retrospective analysis was performed according to data collected from 13 patients with PTLD. At the time of PTLD diagnosis, immunosuppressive therapy was decreased and rapamycin administered. Overall survival, disease-free survival of patients and graft survival were determined.
RESULTS
Among 590 kidney transplant recipients, 13 adult patients with PTLD were included in this study. The mean age of the patients was 42.15 (range: 25-58) years at the time of PTLD diagnosis, and 9 patients were male. Histology was distributed in 9 diffuse large B cell, 1 Malt lymphoma, 1 Burkitt lymphoma, 2 Hodgkin-like PTLD. The response rate to rapamycin alone was 30.8%. The mean overall survival period was 23.38 months and 11 patients are still alive. In total, 10 patients (76.9%) achieved a complete remission with functioning graft in 11 (84.6%) patients.
CONCLUSION
Despite the retrospective focus and limited number of patients, this study provides promising results regarding the effectiveness of stopping calcineurin inhibitors and switching to rapamycin for patients with PTLD.
