Prediction of Lifetime and 10-Year Risk of Cancer in Individual Patients With Established Cardiovascular Disease.

ABSTRACT:

Background

Cardiovascular disease (CVD) and cancer share many common risk factors; patients with CVD also may be at risk of developing cancer.

Objectives

The aim of this study was to derive and externally validate prediction models for the estimation of lifetime and 10-year risk for total, colorectal, and lung cancer in patients with established CVD.

Methods

Data from patients with established CVD from the UCC-SMART cohort (N = 7,280) were used for model development, and from the CANTOS trial (N = 9,322) for model validation. Predictors were selected based on previously published cancer risk scores, clinical availability, and presence in the derivation dataset. Fine and Gray competing risk-adjusted lifetime models were developed for the outcomes total, colorectal, and lung cancer.

Results

Selected predictors were age, sex, smoking, weight, height, alcohol use, antiplatelet use, diabetes, and C-reactive protein. External calibration for the 4-year risk of lung, colorectal, and total cancer was reasonable in our models, as was discrimination with C-statistics of 0.74, 0.64, and 0.63, respectively. Median predicted lifetime and 10-year risks in CANTOS were 26% (range 1% to 52%) and 13% (range 1% to 31%) for total cancer; 4% (range 0% to 13%) and 2% (range 0% to 6%) for colorectal cancer; and 5% (range 0% to 37%) and 2% (range 0% to 24%) for lung cancer.

Conclusions

Lifetime and 10-year risk of total, colorectal, and lung cancer can be estimated reasonably well in patients with established CVD with readily available clinical predictors. With additional study, these tools could be used in clinical practice to further aid in the emphasis of healthy lifestyle changes and to guide thresholds for targeted diagnostics and screening.

Project description:IntroductionCardiovascular disease is a leading cause of mortality in the U.S. Although the risk of cardiovascular disease can be mitigated substantially by following a healthy lifestyle, adhering to a healthy diet and other healthy behaviors are limited by reduced food security. This study aims to determine the association between food security and cardiovascular disease risk.MethodsThree samples from the 2007-2014 National Health and Nutrition Examination Survey were examined: (1) 7,340 non-fasting adults (aged 40-79 years); (2) 13,518 non-fasting adults (aged 20-64 years); and (3) 6,494 fasting adults (aged 20-64 years). Food security was assessed using the U.S. Household Food Security Survey Module, with households categorized as having full, marginal, low, or very low food security. Regressions were conducted in 2018 to test the associations between food security status and odds of ≥20% 10-year cardiovascular disease risk among middle-aged to older adults (OR, 95% CI) and cardiovascular disease risk factors among all adults (β, 95% CI).ResultsCompared with adults with full food security, those with very low food security had higher odds of ≥20% 10-year cardiovascular disease risk (OR=2.36, 95% CI=1.25, 4.46), whereas those with marginal food security had higher systolic blood pressure (β=0.94 mmHg, 95% CI=0.09, 1.80). Compared with adults with full food security, adults with different levels of food security had higher BMIs (marginal: 0.76, 95% CI=0.26, 1.26; low: 0.97, 95% CI=0.34, 1.60; and very low: 1.03, 95% CI=0.44, 1.63) and higher odds of current smoking (marginal: OR=1.43, 95% CI=1.17, 1.75; low: OR=1.47, 95% CI=1.22, 1.77; and very low: OR=1.95, 95% CI=1.60, 2.37).ConclusionsAdults with food insecurity have elevated cardiovascular disease risk factors and excess predicted 10-year cardiovascular disease risk. Substantially improving food security may be an important public health intervention to reduce future cardiovascular disease in the U.S.Population
