Why are anthracyclines considered a red flag in cancer care?

• A. They cause dose-dependent cardiotoxicity leading to irreversible cardiomyopathy
• B. They cause kidney failure
• C. They have no cardiovascular effects
• D. They cause only headaches

Answer: (A)

Anthracyclines pose a serious risk of dose-dependent cardiotoxicity that can progress to irreversible cardiomyopathy. This means the heart damage is related to the total amount given over a patient’s lifetime and may become permanent, leading to heart failure even after treatment ends. Because of this, these drugs are a red flag in cancer care: they can limit how much therapy a patient can safely receive, and they require careful cardiac monitoring (baseline and periodic imaging of heart function), dose planning to stay within safe cumulative limits, and strategies to protect the heart (such as alternative regimens or protective agents like dexrazoxane). While other side effects can occur, the most concerning and defining issue is the potential for lasting heart damage, not kidney failure or only mild cardiovascular effects like headaches.
