Purpose: Up to now, cardiotoxicity of epirubicin has been studied almost exclusively in adult cancer patients. The aim of this study was to investigate epirubicin in children and adolescents, in comparison with doxorubicin. Methods: About 172 soft tissue sarcoma patients (mean age at diagnosis: 8.3 years), treated with epirubicin (median cumulative dose: 450 mg/m2) or doxorubicin (median cumulative dose: 240 mg/m2) within the high-risk group of the CWS-96 study, were examined in a prospective multicentre study. Heart function was analysed by echocardiography, measuring left-ventricular fractional shortening (FS). The median follow up was 27.7 months. Results: Incidence of clinically manifest cardiomyopathy was 0% (0/60; 95% CI: 0-6.0%) in patients treated with epirubicin, and 0.9% (1/108; 95% CI: 0-5.1%) in patients treated with doxorubicin. A further three patients showed subclinical cardiomyopathy. There was no difference in FS between the two treatment arms. Conclusions: Cardiotoxicity was low in our study. For the short term, cardiotoxicity seems to be only a minor problem in patients treated with epirubicin as applied in this cohort.
