mTOR inhibition and its effect on cancer in transplantation

Abstract

A considerable amount of data indicates that transplanted patients are at increased risk for de novo and recurrent cancer. Treatment of this population is difficult. It remains unclear if the immunosuppressive therapy should be continued, tapered or even stopped or if immunosuppressive drugs with antiproliferative properties have beneficial effects in this situation. In various models, mTOR-inhibitors were shown to have immunosuppressive and anti-tumor effects. Here, we have reviewed the current literature trying to clarify if mTOR-inhibition brings advantages for the transplanted patients suffering from tumors.
