Cardiac Effects of Cancer Therapy
Summary of Key Points
Incidence
Cardiomyopathy/Chronic Heart Failure
• Anthracyclines: cardiomyopathy/chronic heart failure occurs in 5% to 20% of patients receiving cumulative doxorubicin (more than 450 mg/m2); the incidence is higher in children
• Other antineoplastics (e.g., mitoxantrone and cyclophosphamide): the incidence of cardiomyopathy/chronic heart failure is less than 2%
• Trastuzumab (not common as a single agent; increased risk with anthracycline)
• Radiation therapy: cardiomyopathy/chronic heart failure is common 5 to 20 years after use of a single anteroposterior port
