Living with Post-transplant lymphoproliferative disease

A complication of organ or stem cell transplant in which immune cells (lymphocytes) grow out of control.

Understanding Post-transplant lymphoproliferative disease

Post-transplant lymphoproliferative disease (PTLD) is a complication of transplantation in which lymphocytes grow without control.

It occurs in people whose immune systems are intentionally suppressed after a solid organ or stem cell transplant. It can range from a mild, noncancerous overgrowth of tissue to a cancerous lymphoma. The digestive tract, nervous system or the transplanted organ are often involved.

Signs & symptoms

Symptoms are often vague and depend on the body parts involved. GARD lists these among the most common:

  • Feeling unwell (malaise)
  • Fever
  • Weight loss
  • Night sweats
  • Tiredness (fatigue)
  • Swollen lymph nodes

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include blood and bone marrow specialists and cancer specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
What symptoms should prompt me to call my transplant team?
How is PTLD confirmed, for example with a biopsy?
Can my immune-suppressing medicines be adjusted?

Quick facts

Symptoms usually startany time in life

PTLD is often caused by the Epstein-Barr virus (EBV), which infects B-cells. A weakened immune system can let EBV reactivate and make these cells grow out of control. It can also happen if a person first catches EBV after the transplant. Why it happens without EBV is not clear.
