Abstract

Anthracycline-induced cardiotoxicity is a frequent complication that can occur at any stage of treatment, even in survivors. To determine maximum aerobic power, quality of life, and left ventricular ejection fraction in childhood cancer survivors treated with anthracyclines. Cross-sectional, observational study. The left ventricular ejection fraction was obtained from the transthoracic echocardiogram report in the medical records. Each patient underwent a 6-minute walk test, assessment of maximum aerobic power on a cycle ergometer, and evaluation of perceived exertion using the EPInfant scale, and finally, their quality of life was evaluated using the pediatric quality of life inventory model. A total of 12 patients were studied, with an average of 16.2years of age. All patients exhibited a left ventricular ejection fraction >60%, the mean distance covered in the 6-minute walk test was 516.7m, and the mean of the maximum aerobic power was 70W. Low quality of life scores were obtained in the physical and psychosocial aspects. In the Pearson test, a weak correlation without statistical significance was found between all the variables studied. Simultaneously with the detection of cardiotoxicity in childhood cancer survivors, it is pertinent to perform physical evaluations as physical condition and cardiotoxicity seem to be issues that are not necessarily dependent.
