What was measured
* Cardiac dysfunction for this outcome measure is defined as moderate cancer therapy related cardiac dysfunction (CTRCD) by 2D Echocardiogram Modified Simpson's Biplane Method of LVEF. Moderate CTRCD is defined as \>10% ejection fraction drop to \<50%. * Patients were assessed for early evidence of dysfunction by strain defined as a relative drop in global longitudinal strain (GLS) by 15% and GLS \> -17%.
Analysis population: Participants were not included in this outcome measure if they did not have GLS.
Groups in this outcome
Arm 1: Doxorubicin and Upfront Dexrazoxane
* Dexrazoxane will be given intravenously on an outpatient basis over 15 minutes on each day that doxorubicin is given. * Dexrazoxane should be given no more than 30 minutes prior to administration of doxorubicin, which is typically given on Day 1 of a 21-day cycle. * Dosing is a 10:1 ratio of dexrazoxane to doxorubicin; doxorubicin is typically given at 75 mg/m2, so dexrazoxane dosing would be 750 mg/m2. * In the event of a national shortage of dexrazoxane, 72-hour infusional doxorubicin can be used instead of dexrazoxane and bolus doxorubicin.
Arm 2: Control (Doxorubicin and Standard of Care Dexrazoxane)
* Doxorubicin is given as standard of care. Doxorubicin is typically given at 75 mg/m2 on Day 1 of a 21-day cycle. * Starting with cycle 5, standard of care dexrazoxane (75 mg/m2) will be given for 4 cycles. * The last 10 patients enrolled after completion of enrollment to Arm 1 will be enrolled to Arm 2.
