title: [Pro and anti-neoplastic effects of immunosuppressive drug in renal transplantation].
abstract: The increased efficiency of immunosuppressive drugs obtained in the last few years has significantly reduced the incidence of acute rejection, prolonging transplant survival rates. The inevitable trade-off was however an increased rate of post-transplant infections and malignancies. Furthermore, this problem might get more and more serious in the next future due to the increasing incidence of cancer in immunosuppressed transplant recipients; the introduction of new immunosuppressive strategies is expected to extend significantly allograft survival. The inclusion of older recipients in transplant programs will also likely increase this problem. Thus, cancer may represent a serious cause of morbidity and mortality in patients otherwise successfully treated by organ transplantation. Nevertheless, effective approaches to deal with malignancies in immunosuppressed patients are still far from the clinical arena. Therefore, once cancer occurs in a transplant recipient, clinicians only have two options: to reduce or withdraw the immunosuppression eventually causing acute or chronic allograft rejection, or to continue the standard immunosuppressive therapy while beginning specific therapy for the malignancy. Several clinical studies suggest that the use of immunosuppressive drugs may result in increased cancer incidence, in transplant as well as autoimmune disease patients. This clinical observation is supported by experimental data showing that these drugs enhance cancer cell growth characteristics and inhibit DNA repair mechanisms, clearly suggesting that the increased incidence of neoplastic disease in patients treated with several immunosuppressive drugs is at least partially independent of their immunosuppressive action. In this scenario it is of particular interest the fact that some immunosuppressive drugs have both an anti-rejection and anti-neoplastic activity. In this review we focus our attention on this potential dual role of immunosuppressive therapy in the development of neoplasia in transplanted patients.
