The anthracyclines (ATC) have been used in the treatment of many pediatric patients with malignancies. Their use, however, has been limited by a serious and potentially irreversible cardiotoxicity. The medical records of pediatric patients with malignancies who received ATC at the Department of Pediatrics, Kyushu University, from January 1985 to December 1994 were reviewed. Among the 120 children with malignancies who received ATC, six patients (5%) developed congestive heart failure, 33 (28%) had subclinical cardiac dysfunction, whereas 81 (66%) showed no evidence of cardiac dysfunction. The incidence of ATC cardiotoxicity increased at higher cumulative doses. The earliest cardiotoxicity, however, was observed in a patient who received 180 mg/m 2 unassociated with other risk factors, showing the marked individual variations in its development. Children younger than 4 years had a higher incidence of cardiotoxicity compared with those older than 4 years ( P < 0.01) and are therefore more vulnerable to ATC cardiotoxicity. Because serial myocardial biopsies and stress testing are not practical in younger children, and radionuclide angiogram is rather costly and not appropriate for frequent evaluation, non‐invasive tests such as echocardiography and electrocardiography (ECG) still play the main role for serial cardiac monitoring in these age groups. Radionuclide angiogram should be added as the confirmatory test modality.
