    Abstract:
    UNLABELLED: Posttransplant lymphoproliferative disorders (PTLD) are a heterogeneous group of lymphoid diseases that occur after solid organ and bone marrow transplantation. We performed a retrospective study to assess the incidence, response to treatment, and patient and graft survival after PTLD. PATIENTS: Between January 1980 and December 2002, 1.96% (n=10) of 509 renal transplant recipients developed PTLD. Seventy percent were men. Mean age was 40 years (range 21-65). They were classified into four groups based upon the type of PTLD: group I, early lesion (n=1); group II, polymorphic PTLD (n=1); group III, monomorphic PTLD (n=7) including five non-Hodgkin lymphoma [NHL] and two Burkitt (BL); and group IV, Hodgkin lymphoma (HL) (n=1). The mean time from transplantation to diagnosis was 77 months (range 4-138). Although only 20% of cases were early presentation, Epstein-Barr virus (EBV) was found in the tumor cells of seven cases. Treatment was individualized according to PTLD type: for group I, immunosuppression reduction (IR); group II, IR plus acyclovir; group III, withdrawal or IR plus chemotherapy and/or surgery in all but one patient who was also treated with anti-CD20 monoclonal antibody and radiotherapy. Interferon was also used in one patient. For group IV, treatment was IR plus radiotherapy. RESULTS: A complete response was achieved in nine cases (90%) with one recurrence. Three patients returned to dialysis. One patient with BL died. CONCLUSIONS: The incidence of PTLD in our center was 1.96%. Patient survival after PTLD was 90%, with 60% maintaining allograft function. Individualized treatment according to extension, histology, and location is mandatory to obtain a high survival rate.
