Abstract

Abstract Acute lymphoblastic leukemia is the most common hematological malignancy at pediatric age. Cardiotoxicity holds the first place among the causes of morbidity and mortality in these patients. Anthracyclines are cytostatic drugs frequently associated with cardiotoxicity. Early diagnosis of cardiac impairment during the treatment of pediatric patients is extremely important, both for modulating future chemotherapy and for administering cardioprotective agents. Long term monitoring after chemotherapy helps to identify the risk of late cardiotoxicity among cancer survivors. There are several biomarkers, already in use or still under study, which may represent an operator-independent alternative for echocardiography in the diagnosis of cardiotoxicity. In case of cardiac damage, the clinician has options for treating or limiting the progression, either with the use of already approved agents, such as Dexrazoxane, or by administrating other cardioprotective drugs. International experts are still attempting to establish the best algorithm for early detection of cardiotoxicity, as well as the most efficient treatment plan in case of already existing myocardial damage in these patients. We present a review on treatment-related cardiotoxicity, including mechanisms of development, useful biomarkers and treatment options, after carefully analyzing specialty literature.
