Is post-transplant lymphoproliferative disorder curable?

Is post-transplant lymphoproliferative disorder curable?

Treatment of PTLD PTLD treatment can be challenging. The goal is to cure PTLD while preserving the function of the transplanted organ. The first line of treatment is a reduction of the immunosuppressive medications the patient is taking.

What is post-transplant lymphoproliferative disorder?

The post-transplant lymphoproliferative disorders (PTLD) are a group of potentially life-threatening conditions that affect patients who have had an organ or bone marrow transplant. PTLD occurs because the immune system of these patients is weakened to allow them to accept the newly transplanted organ or bone marrow.

Is post-transplant lymphoproliferative disorder life-threatening?

Post-transplant lymphoproliferative disorder (PTLD) is a well-known, life-threatening complication of organ transplantation, predominantly occurring after solid organ transplantation (SOT) and hematopoietic stem cell transplantation (HSCT).

What can trigger post-transplant lymphoproliferative disease PTLD?

Your chances of getting PTLD are greatest during the first few months after your kidney transplant, when you are on the highest dose of immunosuppressive drugs. It can also happen later, even several years after your transplant.

What is the survival rate of PTLD?

We reviewed 141 patients diagnosed with PTLD over last 22 years with median follow-up of 2.4 years. The estimated median overall survival of the entire group was 15.0 years. Sub group analysis showed that 5-year overall survival rates of pediatric population were 88% (median not reached).

How long after transplant can you get PTLD?

Most cases occur within the first 6 months after transplant. People who have a stem cell transplant from a partially-matched donor or using stem cells from umbilical cord blood have a higher risk of developing PTLD than people who have a stem cell transplant from a well-matched donor.

Is PTLD a non Hodgkin lymphoma?

Many cases of polymorphic cases are Epstein-Barr virus positive. Monomorphic PTLD is the most common form and is characterized by the development of malignant lymphoma, usually diffuse large B-cell lymphoma (this is the most common type of non-Hodgkin lymphoma in the United States).

How does EBV cause PTLD?

The EBV-specific cytotoxic T cells are mostly directed against lymphoblasts expressing the growth program. Decrease in number and function of T cells due to immunosuppressive drugs might lead to uninhibited growth of these cells and eventually to PTLD.

How is EBV PTLD treated?

Rituximab monotherapy is the treatment of choice for EBV-PTLD (Table 8) with positive outcome reported in almost 70% of patients. Rituximab is usually administered once weekly for up to 4 doses while monitoring EBV viral load.

Is PTLD NHL?

With PTLD, the body makes too many lymphocytes (a type of white blood cell) or the lymphocytes don’t act normally. PTLD behaves like a fast-growing (aggressive) type of non-Hodgkin lymphoma (NHL). Most PTLDs are B-cell lymphomas (less than 15% are T-cell lymphomas).
