PURPOSE: Cardiovascular disease (CVD) is a major non-cancer cause of mortality among cancer survivors, and statin therapy is the mainstay of cardiovascular risk management. However, little is known about adherence to statin therapy relative to current guidelines for the management of cholesterol among cancer survivors. We investigated the prevalence of statin-eligible but untreated individuals among cancer survivors and factors associated with underuse of statins.
METHODS: We used US National Health and Nutrition Examination Survey data (2011-2016) and identified 706 cancer survivors and matched controls (1:2) by age and sex. We identified participants who met the American College of Cardiology/American Heart Association (2018) guidelines but were not currently in treatment. We estimated the proportion of patients who were statin-eligible but untreated and performed multivariable logistic regression analysis to identify the factors associated with underuse of statins.
RESULTS: The mean age of the total sample was 62.2 years (standard deviation, 9.1). Among the total participants, 37.5% of cancer survivors and 37.2% of controls were statin-eligible but untreated. The crude statin-eligible untreated proportion was 41.2% among cancer survivors who had received a cancer diagnosis within 3 years and 40.3% among long-term survivors of 10 years or more. In multivariate analysis, old age, male sex, lack of a usual source of care, current smoking, and low household income were significantly associated with statin-eligible untreated status.
CONCLUSIONS AND IMPLICATIONS FOR CANCER SURVIVORS: More than one-third of cancer survivors were statin-eligible but untreated under current guidelines. There is room for improvement to reduce the burden of non-cancer mortality by managing traditional cardiovascular risk factors.
