[Recurrence of Wilm's tumor following a 9-year disease-free interval].

We report the case of a 25-year old female patient, who presented with intrapulmonary metastases of a Wilms' tumor nine and a half year after initial therapy of a stage I tumor with surgery, local radiation and combined chemotherapy. In general, relapses of Wilms' tumor occur within two year after nephrectomy. Recurrences after more than 7 years are very rare. A relapse of a Wilms' tumor in an adult patient after more than 9 years is not yet published. We treated our patient according to the therapeutic procedure, which is recommended by the National Wilms' Tumor Study as curative treatment of relapses in childhood: complete resection of pulmonary metastases, irradiation of the whole lunge and repeatingly combined chemotherapy with actinomycin D and vincristin. The patient is doing well without evidence of tumor 13 months after thoractomy. A short review of the literature is given.
