title: Tumors after renal transplantation.
abstract: The purpose of this retrospective study was to analyze the development of malignancies after renal transplantation. 633 renal graft recipients with an organ function longer than 1 year were followed up over a mean period of 67.6 +/- 48.7 months. Only 12 recipients received grafts from living-related donors. 38 recipients (6.0%) exhibited cancer of either the skin, the genitourinary system, the bronchial system, the female breast, or the colon. All tumors were de novo malignancies. The number of patients developing a tumor was significantly higher in the cyclosporine-treated group than in patients with conventional immunosuppression. 15 patients died within a mean survival time of 7.7 +/- 12.1 months. The frequency of disorders makes it necessary for organ transplant recipients to have routine examinations both before and at regular intervals after transplantation. This includes examination of the patient's skin, native kidneys and cervical smears for females.
