Echocardiographic evaluation of patients undergoing cancer therapy.

As advances in oncology therapies lead to significant improvement in life expectancy of many cancer entities, short-, and long-term cardiac side effects of oncology treatments gain increasing importance. In search of new screening modalities, echocardiography currently presents the best established and clinically easily feasible tool to detect cardiotoxicity in patients undergoing cancer therapy. This review focusses on the most commonly used oncology therapies and aims to give a practical approach to guide clinicians caring for this growing number of patients.

EPR studies on the oxidation of hydroxyurea to paramagnetic compounds by oxyhemoglobin.
