Cardiotoxicity of epirubicin and doxorubicin: a double-blind randomized study.

24 patients with non-Hodgkin lymphoma were randomized into two multidrug regimens including either epirubicin (N = 12) or doxorubicin (N = 12) to establish the cardiotoxicity of each treatment modality. At cumulative doses of 400-500 mg/m2 left ventricular ejection fraction (LVEF) at rest determined by radionuclide angiocardiography decreased significantly more in the doxorubicin (-15 +/- 11%) than in the epirubicin group (0 +/- 13%, p less than 0.005). During epirubicin therapy no clinically significant cardiotoxicity developed, but a decrease larger than 10% in LVEF was seen in 4 of 12 patients at a mean cumulative level of 450 mg/m2. During doxorubicin therapy 1 patient developed a heart failure at a cumulative level of 200 mg/m2 and, altogether, in 7 patients LVEF decreased more than 10%. The monitoring of cardiac toxicity is imperative in patients treated with doxorubicin and is advisable if the patient is expected to receive epirubicin at more than 450 mg/m2.
