Overview
Brief Summary
Solid organ transplantation is an important therapeutic option for children with a variety of end stage diseases. However, the same immunosuppressive medications that are required to prevent the child's immune system from attacking and rejecting the transplanted organ can predispose these individuals to developing a very serious cancer that is linked to Epstein-Barr virus (EBV).
Detailed Description
EBV-associated post-transplant lymphoproliferative disease (PTLD) is the most common malignancy in children after transplant. Diagnosis and effective treatment of the EBV-associated cancer is hampered by our inability to determine which children are at risk of developing these cancers and to detect the cancer at an early stage. In this study, we plan to test new "biomarkers" in the blood of children that will tell us very early on if the child is at risk of developing the EBV-associated cancer or if the cancer is present. These studies provide new opportunities for detection, diagnosis, and treatment of children with EBV-associated, post-transplant cancer.
