Genitourinary Neoplasia after Kidney Transplantation

The incidence of cancers in kidney transplants has steadily increased following a dramatic rise in the number of renal transplantations, use of potent immunosuppressive drugs and longer survival for transplant recipients (1). Consequently, neoplastic disorders are an important cause of the late morbidity and mortality in renal transplant recipients (RTRs). Although tendency to develop skin cancer (2) and lymphoproliferative disorders (3) is clearly increased after renal transplantation, the association between this setting and genitourinary tumor is not clearly known. There have been a few reports on the incidence of malignancy from transplant registries. It is difficult to precisely compare the incidence with that in the general population using data from small, single-center studies (1).
