Long-term cardiovascular disease mortality among survivors of adolescent and young adult cancer

Our aim was to assess the risk of cardiovascular disease (CVD) mortality in US 5-year survivors of adolescent and young adult (AYA) cancer compared with those of the general population and contemporaneous 5-year survivors of childhood cancer.
Methods and results

A total of 160 834 5-year AYA cancer survivors (aged 15–39 years at diagnosis) were included, representing 2 239 390 person-years of follow-up. Overall, 2910 CVD deaths occurred, which was 1.4-fold [95% confidence interval (CI) 1.3–1.4] that expected in the general population, corresponding to 3.6 (95% CI 3.2–3.9) excess CVD deaths per 10 000 person-years. The highest risk of cardiac mortality was experienced after Hodgkin’s lymphoma (HL), and the highest risk of cerebrovascular mortality was observed with central nervous system (CNS) tumors. Even survivors in their 6th and 7th decades of life, the risk of CVD mortality remained markedly higher than that of the matched general population. Competing risk analysis showed that the cumulative mortality of CVD was elevated among AYA cancer survivors compared with childhood cancer survivors during the whole study period.

Conclusion

Long-term AYA cancer survivors have a greater risk of CVD mortality than the US general population and childhood cancer survivors. Vulnerable subgroups, especially survivors of HL and CNS tumors, require continued close follow-up care for cardiovascular conditions throughout survivorship.
