Bilaterality is uncommon in Wilms' tumor, being present in 4% to 8% of the cases. We report the combined experience of two children's hospitals in one city over a 20-year period. We encountered nine cases of synchronous bilateral nephroblastoma (National Wilms' Tumor Study 3, stage V). Age at diagnosis ranged from 9 to 41 months (mean 23 months). There were five girls and four boys. Associated findings include nephroblastomatosis in three cases (33%), one of which also had a familial history; undescended testis in two cases; and minor anomalies in two other cases. Surgical treatment consisted of unilateral nephrectomy with contralateral partial nephrectomy or tumorectomy in six cases, nephrectomy with contralateral biopsy only in two cases, and the other patient had bilateral biopsies initially, followed at a later date by partial nephrectomy on one side. All patients received chemotherapy; actinomycin D (AMD) only was used in the oldest case, vincristine and AMD in five cases, to which was added cyclophosphamide in one case and adriamycin in two. Seven patients received radiation therapy. Seven out of the nine patients survived more than 2 years (77%); five are well, off chemotherapy, with no evidence of disease from 4 to 11 years after diagnosis. Two patients suffered from chronic renal failure and one died from complications after renal transplantation more than 19 years after diagnosis. The two patients who died from their disease presented with more advanced tumor. Therefore, the agressiveness of multimodal therapy can be tailored according to stage and histology, and effective chemotherapy allows maximal preservation of renal parenchyma in patients with stage I and II tumors.
