PURPOSE: To describe the high-risk profile group, susceptible to develop anthracycline-induced cardiomyopathy in children with acute leukemia. METHODS: The study involved 35 pediatric patients diagnosed with acute lymphoblastic (ALL) or acute myeloblastic leukemia (AML), from March 2014 to December 2016. Serologic markers used for the analysis of cardiac dysfunction were troponin T, NT-proBNP and PCRhs. Also, the patients have had echocardiographic evaluation at the beginning of treatment to determine LVEF, SF and A, E, E' Doppler waves. RESULTS: Positive linear correlation was shown between NT-proBNP and leukocyte values, NT-proBNP and blast cells value, and NT-proBNP and LDH. Significant linear negative correlations between LVEF with leukocyte values, blast cells values, LDH, SF and leukocyte values, LVEF and NT-proBNP values and LVEF and troponin T values were also identified. A weak negative correlation between E/E' ratio and blast cells values has been observed. All of these correlations were statistically significant (p<0.05). CONCLUSIONS: Leukocyte value, as well as the other serological markers assessed (NT-proBNP, Troponin T), are useful tools to evaluate the risk of anthracycline-induced cardiotoxicity. The variation of the biological markers at the beginning of the cytotoxic treatment confirms the presence of an early myocardial dysfunction, emphasizing the importance of systematic evaluation of this particular group of patients.
