De Novo Visceral Malignancies in Renal Transplant Recipients: A Single Center Experience of 2054 Recipients for More Than 30 Years.

We report the incidence and pattern of malignancies in renal transplant recipients from our department.Between March 1983 and August 2013, the records of 2054 renal transplant recipients from our department were retrospectively reviewed with regard to type of neoplasm, age, gender, interval between the transplant and the diagnosis of malignancy, immunosuppressive regimens, graft functional status, and rejection episodes.Among the 2054 renal transplant recipients, visceral malignancies developed in 74 patients (3.6%). The mean age at transplant was 43.9 years, and the mean age at death was 61.9 years. Sixty-eight patients (91.9%) died with a functioning graft. Fifty-four (73%) died during follow-up. The mean time from transplant to malignancy was 96.4 months, and from malignancy to death was 27.5 months. No difference regarding the type of immunosuppression, the type of donor, or the interval between transplant and malignancy was detected when we compared cancers.Malignancies after a renal transplant display aggressive behavior and occur more frequently several years after the transplant, but they also may occur earlier. The type of immunosuppression, the type of donor, or the interval between transplant and malignancy do not differ significantly among cancers.
