The risk of cardiac related mortality in cancer survivors is linked to the age at which the diagnosis of cancer is made.
Highlights
- Age of diagnosis of cancer survivors determines their risk of death from heart disease.
- Cancer survivors diagnosed at ages 15 to 19 years had 4.2 times higher risk of death from heart disease.
- Survivors who were 35 to 39 years old at cancer diagnosis had 1.2 times higher risk of death from heart disease
Researchers examined data from these survivors and found:
- Six percent of deaths were caused by heart disease.
- Cancer survivors diagnosed at ages 15 to 19 years had 4.2 times higher risk of death from heart disease compared to the general population of similar age and gender.
- Survivors who were 35 to 39 years old at cancer diagnosis had 1.2 times higher risk of death from heart disease compared to the general population of similar age and gender.
"It is important for survivors because it empowers them by providing them with their long-term chances of a specific side effect of cancer treatment." he added.
The significance of age at diagnosis was most apparent for survivors of Hodgkin lymphoma - cancer of the lymphatic system.
6.9% of survivors who were diagnosed with Hodgkin lymphoma at ages 15-19 years had died of heart disease by age 55 years, while 2% of those diagnosed at ages 35-39 years.
Survivors of Hodgkin lymphoma experienced 3.8 times the risk of death from heart disease than expected from members of the general population of similar age and gender.
Survivors of other types of cancer also had a higher than expected risk of death from heart disease including: leukemia, genitourinary cancer, lung cancer, breast cancer, and others.
Researchers noted the study lacks detailed information on exposure to cancer treatments: radiotherapy and chemotherapy.
This new research provides insight into the cardiotoxicity of cancer treatments given in the past to teenagers and young adults .
