Health Effects After Anthracycline and Radiation Therapy (HEART): Dexrazoxane and Prevention of Anthracycline-related Cardiomyopathy
What is the purpose of this trial?
We will determine echocardiographic and serum biomarkers of cardiac injury in a study of long-term pediatric T-cell leukemia and Hodgkin lymphoma survivors enrolled on 3 front-line Children's Oncology Group (COG) clinical trials (POG 9404, 9425, 9426) between 1996-2001 with certain features. Our primary aim will be to determine whether patients randomized to the experimental dexrazoxane (DRZ) arms have decreased markers of myocardial injury compared with patients treated without dexrazoxane (DRZ). This will include a one-time measurement of an echocardiographic index of pathologic left ventricular (LV) remodeling (wall thickness-dimension ratio), complemented by serum biomarkers and a physical examination for signs and symptoms of cardiomyopathy/heart failure (CHF). We will also evaluate whether DRZ's cardioprotective effect is modified by anthracycline dose, chest radiation, and selected demographic factors (age at cancer diagnosis, current age, sex).
