passages.text: Two children with Wilms tumor of the left kidney experienced severe anthracycline cardiomyopathy after irradiation to the tumor bed and conventional dosage of doxorubicin. The cardiomyopathy is attributed 1) to the fact that radiation fields for left Wilms tumor include the lower portion of the heart and 2) to the interaction of doxorubicin and irradiation on cardiac muscle. It is recommended that doxorubicin dosage be sharply restricted in children with Wilms tumor of the left kidney who receive postoperative irradiation.
