Risk of Cardiovascular Disease in Cancer Survivors after Systemic Treatment

  Figure 1. Flow Chart Among 471,569 cancer patients identified between 2004 and 2019, 206,452 received systemic cancer treatment within 12 months of diagnosis. Of these, 91,407 were alive 3 years later (the index date) and had no evidence of recent cancer treatment or relapse. At index date, each survivor was matched to 5 cancer-free individuals from the general population and followed for up to 5 years for study outcomes or censoring. ∗For breast and prostate cancer, systemic treatment included (anti)hormonal agents.

  Figure 2. Outcomes in Cancer Survivors and Comparison Individuals, by Cancer Type Cardiovascular outcomes in cancer survivors and their matched cancer-free comparators during 5-year follow-up. Risks are shown as cumulative incidences and adjusted HRs with 95% CIs. Outcomes are stratified by cancer type at first cancer diagnosis. Results indicate that cardiovascular risk is increased in cancer survivors, with variations across cancer types. These include ischemic heart disease, heart failure, atrial fibrillation/flutter, peri-/endo-/ myocarditis, valvular heart disease, and other cardiac arrhythmias, as well as aortic aneurysm and dissection, stroke, venous thromboembolism, kidney failure, and hypertension.

  Figure 3. Outcomes in Cancer Survivors and Comparison Individuals, by Treatment Group Cardiovascular outcomes in cancer survivors and their matched cancer-free comparators during 5-year follow-up. Risks are shown as cumulative incidences and adjusted HRs with 95% CIs. Outcomes are stratified by cancer treatment received within the first 12 months after initial diagnosis. Results indicate that cardiovascular risk is increased in cancer survivors and varies by treatment type. (A) includes ischemic heart disease, heart failure, atrial fibrillation/flutter, and peri-/endo-/myocarditis. (B) includes stroke, venous thromboembolism, kidney failure, and hypertension. (C) includes valvular heart disease, other cardiac arrhythmias, aortic aneurysm/dissection. ∗Hormonal treatment was evaluated only in survivors of breast and prostate cancer. HER2 = human epidermal growth factor receptor 2.

  Figure 4. Cumulative Incidence Curves for Selected Cancer Types Cumulative incidence curves for cardiovascular outcomes in cancer survivors and their matched cancer-free comparators during 5-year follow-up, stratified by 4 cancer types: breast cancer, colorectal cancer, hematological malignancies, and lung cancer. Results indicate that cardiovascular risk is increased in cancer survivors and varies by cancer types. These include ischemic heart disease, heart failure, atrial fibrillation/flutter, peri-/endo-/myocarditis, valvular heart disease, and other cardiac arrhythmias, as well as aortic aneurysm and dissection, stroke, venous thromboembolism, kidney failure, and hypertension.

  Figure 5. Cumulative Incidence Curves for Selected Treatment Groups Cumulative incidence curves for cardiovascular outcomes in cancer survivors and their matched cancer-free comparators during 5-year follow-up, stratified by treatment groups: chemotherapy, targeted therapy, and hormonal therapy. These include ischemic heart disease, heart failure, atrial fibrillation/flutter, peri-/endo-/myocarditis, valvular heart disease, and other cardiac arrhythmias, as well as aortic aneurysm/dissection, stroke, venous thromboembolism, kidney failure, and hypertension. ∗Hormonal treatment was evaluated only in survivors of breast and prostate cancer.

  Central Illustration. Cardiovascular Risk in Cancer Survivors A total of 91,407 cancer survivors with no signs of active disease were matched to 457,035 cancer-free individuals from the general population. During the 5-year of follow-up, cancer survivors had increased risk of several cardiovascular diseases, with substantial variation by cancer type and prior cancer treatment.
