Abstract
Background. Posttransplantation lymphoproliferative diseases (PTLD) are mainly Epstein-Barr virus (EBV)-associated disorders of B-cell origin. Due to the rarity of monomorphic T-cell PTLD (T-PTLD), knowledge about pathogenesis, risk factors, therapy, and prognosis relies predominantly on case reports and small series. Therefore, we aimed to provide an overview and a retrospective analysis of this rare PTLD subtype. Methods. We analyzed all available articles on T-PTLD in the PubMed database as well as in our own databases (Institute of Pathology/Department of Paediatric Haematology and Oncology, Hannover Medical School) from 1988 to 2010. Reevaluated parameters were gender, age, transplanted organ, immunosuppressant regimen, time between transplantation and T-PTLD manifestation, T-PTLD subtype, virus positivity, localization, therapy, and follow-up. Results. A total of 163 cases were evaluated. We found that hematopoietic stem cell transplantation was associated with early-onset T-PTLD, whereas late onset occurred after immunosuppression with steroids and azathioprine without administration of calcineurin inhibitors. The major independent favorable prognostic factors were T-PTLD of the large granular lymphocytic leukemia subtype, young age, and a combination of radiotherapy/radiochemotherapy and reduced immunosuppression, whereas the hepatosplenic T-cell lymphoma subtype and cases with involvement of bone marrow, the central nervous system, or graft had an adverse prognosis. Conclusion. T-PTLD is a heterogeneous group of different aberrant T-cell proliferations and represents a significant complication following transplantation, showing a uniformly poor prognosis.
