Abstract

Background: Childhood cancer survivors are at increased risk of cardiovascular disease (CVD), which may be associated with traditional CVD risk factors. We used CVD risk aggregation instruments to describe survivor cardiometabolic health and compared their results with sibling controls. Methods: Traditional CVD risk factors measured in 110 survivors and 31 sibling controls between 15 and 39 years old were aggregated using Pathobiological Determinants of Atherosclerosis in Youth (PDAY) scores and the Framingham Risk Calculator (FRC) and expressed as ratios. The PDAY odds ratio represents the increased odds of currently having an advanced coronary artery lesion, and the FRC risk ratio represents the increased risk of having a myocardial infarction, stroke, or coronary death in the next 30 years. Ratios are relative to an individual of similar age and sex without CVD risk factors. Results: The median PDAY odds ratio for survivors was 2.2 (interquartile range 1.3-3.3), with 17% >4. The median FRC risk ratio was 1.7 (interquartile range 1.0-2.0), with 12% >4. Survivors and siblings had similar mean PDAY odds ratios (2.33 vs 2.29, P =.86) and FRC risk ratios (1.72 vs 1.53, P =.24). Cancer type and treatments were not associated with cardiometabolic health. There was a suggested association for physical inactivity with PDAY odds ratios (r = 0.17, P =.10) and FRC risk ratios (r = 0.19, P =.12). Conclusions: Cardiometabolic health is poor in childhood cancer survivors but not different than that of their siblings, highlighting the importance of managing traditional CVD risk factors and considering novel exposures in survivors.
