BACKGROUND: Although anthracycline-related cardiomyopathy is a life-threatening complication during intensive treatment for hematological malignancies, clinical features and outcomes of this type of cardiomyopathy have been unclear because of limited reports in the literature.
METHODS: We analyzed three cases of anthracycline-related cardiomyopathy among 996 patients with either acute myelogenous leukemia (285), acute lymphoblastic leukemia (37), or malignant lymphoma (674) at our hospital during the period from 2006 to 2016.
RESULTS: All patients showed accumulation of anthracycline within a proper range (< 500 mg/sqm). Two patients (Hodgkin lymphoma and acute lymphoblastic leukemia) showed acute heart failure (AHF) with ejection fraction (EF) of 30 and 40% after 4.5 and 5 years after diagnosis, respectively. For AHF, diuretics and carperitide were administered to control in-out balance. The remaining patient (follicular lymphoma) showed ventricular fibrillation (VF)/ventricular tachycardia (VT) with EF of 40% at 5 years after diagnosis. In this patient, immediate cardioversion made VF/VT to normal sinus rhythm, and then, amiodarone was given. Furthermore, implantable cardioverter defibrillator was set up for VF/VT. In all patients, β blocker and/or angiotensin-converting enzyme inhibitor (ACE-I) were administrated to prevent recurrence of anthracycline-related cardiomyopathy. Consequently, two of three patients showed mild improvement of cardiac function.
CONCLUSION: Our study indicates that late-onset (4 to 5 years) anthracycline-related cardiomyopathy can develop, though range of anthracycline accumulation is in proper range. Thus, a cautious follow-up by ECG and UCG is required. Furthermore, the early treatment after the onset of anthracycline-related cardiomyopathy should be also needed to improve the poor outcome.
