However, these survivors are also at substantially increased long‐term risk of morbidity and mortality, especially from treatment‐related cardiotoxicity. Preventing these risks is now a priority when treating children and adolescents with cancer. Dexrazoxane reduces the risk of anthracycline‐induced cardiotoxicity among adults and children with cancer without reducing its antineoplastic effects or event‐free survival. Thus, it should be strongly considered as a part of therapy for children and adolescents treated with anthracyclines.
