title: Kidney transplantation in patients with Wilms' tumor.
abstract: We report our experience of renal transplantation in three patients treated for Wilms' tumor (with lung metastasis in two of them), and review 26 previously reported cases in order to define the current indications of transplantation in this setting. Our patients, aged 5-12 years, were transplanted 13-95 months after completion of Wilms' tumor treatment. All three are alive and tumor-free, two with a functioning graft 20 and 97 months after transplantation. Two findings emerge from the review of the literature. First, posttransplant mortality is influenced by the delay between completion of tumor treatment and transplantation. Mortality reaches 79% when that delay is less than one year but falls to 27% when that delay exceeds one year. Second, the prognostic value of pretransplant metastasis depends on its location. All four patients with pretransplant abdominal metastasis died with active metastatic disease. By contrast, of three patients treated before transplantation for metastasis confined to the lung, two are alive and tumor free. We conclude that renal transplantation should be offered to patients successfully treated for Wilms' tumor for at least one year, even if the disease has been complicated by pulmonary metastasis. Several long-term survivors attest that the disease can be cured even under maintenance immunosuppression.
