Are anthracyclines cardiotoxic?
Anthracyclines remain an important class of drugs in the treatment of cancer, but also remains a problematic chemotherapeutic agent given their cardiotoxic effects.
Is anthracycline-induced heart failure reversible?
A previous and more dated classification identified three distinct types of anthracycline-induced cardiotoxicity (Table 2): acute, occurring after a single dose, or a single course, with the onset of symptoms within 14 days from the end of treatment, which is usually reversible; early-onset chronic, occurring within 1 …
Why does cyclophosphamide cause cardiotoxicity?
The precise mechanism of cyclophosphamide-induced cardiac toxicity has not been established. Cyclophosphamide metabolites are believed to cause oxidative stress and direct endothelial capillary damage with resultant extravasation of proteins, erythrocytes, and toxic metabolites (Figure 2).
How long does cardiotoxicity last for?
The median time elapsed between the end of chemotherapy and cardiotoxicity development was 3.5 (quartile 1 to quartile 3, 3–6) months. In 98% of cases (n=221), cardiotoxicity occurred within the first year. Twenty-five (11%) patients had full recovery, and 160 (71%) patients had partial recovery.
Which chemotherapy drugs are the most toxic?
Direct pairwise meta-analysis results also revealed that the gemcitabine + carboplatin chemotherapy regimen was the most toxic regimen in hematologic for AOC patients among 8 chemotherapy regimens.
What is the main long term side effect for the chemotherapy drug type anthracycline?
One of the main concerns with anthracyclines is cardiotoxicity — damage to the heart muscle. The risk of a complication such as heart failure can be particularly high when anthracyclines are used to treat a type of cancer known as acute myeloid leukemia, which on its own raises the risk of heart infections.
