Bilateral Wilms' tumor and secondary malignancies.
A series of six patients with bilateral Wilms' tumor (nephroblastoma) is presented. Multimodal therapy yielded a survival rate of 83% at 2 yr of follow-up. However, at the end of a later follow-up period only two patients (33%) were alive. of the 4 patients who died. Only 1 died of Wilms' tumor. One died of complications of aggressive chemotherapy and two patients died after 12 and 16 yr following treatment of secondary malignant tumors arising in the irradiated region. Patients with bilateral tumor should be followed at regular intervals for the duration of life for the occurrence of secondary malignant tumors.
