Post Transplant Lymphoproliferative Disorders (PTLD)

Post Transplant Lymphoproliferative Disorders (PTLD). PTLD. PTLD is a group of lymphoproliferative disorders that range from hyperplasias to aggressive non-Hodgkin’s lymphoma PTLD is seen after both solid organ and stem cell transplant 90% of PTLDs are Ebstein-Barr Virus (EBV) positive.

  1. Post Transplant Lymphoproliferative Disorders(PTLD)

  2. PTLD • PTLD is a group of lymphoproliferative disorders that range from hyperplasias to aggressive non-Hodgkin’s lymphoma • PTLD is seen after both solid organ and stem cell transplant • 90% of PTLDs are Ebstein-Barr Virus (EBV) positive

  3. Incidence • PTLD occurs in 1% to 25% of solid organ transplant patients • PTLD occurs in < 2% of stem cell transplant patients • Incidence is 4 times higher in pediatric transplant patients versus adults

  4. Incidence by Type of Organ Transplanted • Intestinal transplant 18% • Lung 8% • Heart 3% • Liver 3% • Renal <1%

  5. Clinical Presentation • Some patients are asymptomatic • Others may have non specific symptoms • Fever • Malaise • Weight loss • May resemble infectious mononucleosis • Enlarged tonsils • Lymphadenopathy • Intestinal Perforation

  6. Systems Potentially Involved in PTLD • Central Nervous System • Bone Marrow • Kidneys • Liver • Lungs • Small intestines • Spleen

  7. Characterization • Early PTLD presents within one year following transplantation • 60% develop within one year • Late PTLD occurs more than one year post transplant • 30% develop within 1 to 5 years • 10% develop after 5 years

  8. Risk Factors • EBV seronegative recipient • Type of Organ transplanted • Type of immunosuppression • Simultaneous cytomegalovirus disease • Younger Age • Male

  9. Prevention/Monitoring • EBV Surveillance • Monitor EBV-DNA load • EBV vaccine • Not standard treatment • Anti-viral agents • Questionable value • Agents used include Acyclovir & Ganciclovir

  10. Treatment of PTLD • Reduction of Immunosuppression therapy • Anti-viral agents and IVIG are of limited value • Interferon alpha • Rituximab • CHOP • Doxorubicin, Cyclophosphamide, Vincristine and Prednisone

  11. Conclusion • Prognosis is poor • 5 year survival rates • 25 to 60% • High mortality rate • Lack of standard treatment
