Abstract

BACKGROUND: Posttranplant lymphoproliferative disorder (PTLD) is a fatal complication of organ transplantation and standard treatment is either ineffective or too toxic to tolerate. This study aims to evaluate the characteristics of PTLD patients retrospectively.
METHODS
We enrolled 2,630 kidney recipients who underwent transplantation from April 1979 to June 2007. And we retrospectively reviewed clinical manifestations of PTLD.
RESULTS
Among one hundred ninety post-transplant malignancies from 2,630 renal recipients, 11 PTLD were diagnosed during 195.3+/-11.5 months (0~388 months) of mean follow up duration. PTLD predominantly occurred in male (Male : Female=10 : 1) and mean age of PTLD patients at the time of PTLD diagnosis was 51+/-15 year (18~71 year). Mean time interval to PTLD diagnosis were 126.6+/-74.8 months (6~240 months). In aspect of WHO classification, there were no early lesion, 1 polymorphic PTLD (9.1%), 10 monomorphic PTLD (90.9%) and no other types. In aspect of involved organ, GI tract was involved in 1 case, lung in 2 cases, bone in 2 cases, spleen in 2 cases, neck node in 2 cases, liver in 1 case, and multiple organs in 1 case.
CONCLUSIONS
Our findings showed that the prevalence of PTLD was 0.46%, which was less than reports from Western countries. We also found that the late onset PTLD was more than early onset one, which was another difference from previous reports.
