Cardiotoxicity of oncological treatment in children.

The incidence of complications after antineoplastic therapy is increasing in relation to the incidence of cancer and prolonged survival rate. Cardiotoxicity is one of the major complications, and it may occur during the therapy or many years after its termination, often leading to heart failure. Cardiotoxicity has been attributed particularly to cytostatics from the group of anthracycline antibiotics and radiotherapy, which are widely used in oncological treatment.
