Long-term cardiac follow-up of children treated with anthracycline doses of 300mg/m2 or less for acute lymphoblastic leukemia
Background The cardiotoxic effect of anthracyclines has been well described for moderate to high cumulative doses (>350mg/m2). However, the question of whether sub-clinical signs of cardiomyopathy may develop and progress over time in children receiving doses of

However, the question of whether sub-clinical signs of cardiomyopathy may develop and progress over time in children receiving doses of <350mg/m2 is controversial. The aim of the present study was to examine cardiac function with serial echocardiography from diagnosis to last follow-up, relapse, or death, and to investigate whether suspected risk factors (e.g., age at diagnosis, gender, cumulative dose, and length of follow-up) had a significant influence on cardiac function. Procedure An unselected cohort of 80 patients treated with multi-drug chemotherapy including anthracycline doses of 300mg/m2 or less for childhood acute lymphoblastic leukemia was followed with serial echocardiograms. The deviations of each echocardiogram from normal values for the same age and body-surface areas were calculated. The influences of risk factors were analyzed using univariate and multivariate regression. Lowess curves of time dependence were calculated. Results All echocardiographic parameters including ejection fraction (EF) deteriorated significantly over time. Male gender was significantly associated with systolic dilatation of the left ventricle and positively associated with left ventricular mass. Reduction of EF was significantly associated with age at diagnosis and male gender. Conclusions Anthracycline doses of <300mg/m2 may contribute to a decline in cardiac function over time. Although the deterioration in cardiac parameters was not associated with clinical symptoms, life-long cardiac surveillance for these patients is important to establish the impact of low-dose anthracycline therapy on long-term cardiac health.
