Cancer is a well known complication about long term transplantation. Cancer outcomes are due to the immunosuppressive treatment that prevents transplanted people from rejection. By lowering the effectiveness of the immune system, immune cells are no longer able to seek and destroy cancer cells.
The goal here is to study immunes cells population of people that were transplanted 10 years ago and are now treated either by a corticosteroid - azathioprine association, or only by cyclosporine A.
