Late Effects of Treatment for Childhood Cancer (PDQ®): Treatment - Patient Information [NCI] - Cardiovascular System
Heart and blood vessel late effects are more likely to occur after treatment for certain childhood cancers.
Treatment for these and other childhood cancers may cause heart and blood vessel late effects:
Radiation to the chest and certain chemotherapy drugs increase the risk of heart and blood vessel late effects.
The risk of health problems involving the heart and blood vessels increases after treatment with the following:
- Radiation to the chest or spine: The risk of problems depends on the part of the heart that was exposed to radiation, the amount of radiation given, and whether the radiation was given in small or large doses.
- Radiation to the brain or neck: The risk of problems depends on the part of the brain or neck that was treated with radiation and the amount of radiation given.
- Chemotherapy: Chemotherapy with anthracyclines such as doxorubicin, daunorubicin, idarubicin, epirubicin, and mitoxantrone. The risk of problems depends on the total dose of anthracycline given. It also depends on whether a drug called dexrazoxane was given during treatment with anthracyclines to lessen heart and blood vessel damage.
- Stem cell transplant.
- Biologic therapy.
Childhood cancer survivors who were treated with radiation to the chest or chemotherapy using anthracyclines are at greatest risk. New treatments that decrease the amount of radiation given and use lower doses of chemotherapy may decrease the risk of heart and blood vessel late effects.
The following may also increase the risk of heart and blood vessel late effects:
Late effects that affect the heart and blood vessels may cause certain health problems.
