IMPORTANCE:

Aspirin use has been associated with reduced risk of cancer mortality, particularly of the colorectum. However, aspirin efficacy may be influenced by biological characteristics, such as obesity and age. With the increasing prevalence of obesity and conflicting data regarding the effect of aspirin in older adults, understanding the potential association of aspirin use with cancer mortality according to body mass index (BMI) and age is imperative.

OBJECTIVES:

To investigate the association of aspirin use with risk of all-cause, any cancer, gastrointestinal (GI) cancer, and colorectal cancer (CRC) mortality among older adults and to perform an exploratory analysis of the association of aspirin use with mortality stratified by BMI.

DESIGN, SETTING, PARTICIPANTS:

This cohort study evaluated aspirin use among participants aged 65 years and older in the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial at baseline (November 8, 1993, to July 2, 2001) and follow-up (2006-2008). Analysis began in late 2018 and was completed in September 2019.

MAIN OUTCOMES AND MEASURES:

All-cause, any cancer, GI cancer, or CRC mortality. Multivariable hazard ratios (HRs) and 95% CIs were calculated using time-varying Cox proportional hazards regression modeling, adjusting for additional factors.

RESULTS:

A total of 146 152 individuals (mean [SD] age at baseline, 66.3 [2.4] years; 74 742 [51.1%] women; 129 446 [88.6%] non-Hispanic white) were included in analysis. The median (interquartile range) follow-up time was 12.5 (8.7-16.4) years, encompassing 1 822 164 person-years. Compared with no use, aspirin use 1 to 3 times per month was associated with reduced risk of all-cause mortality (HR, 0.84; 95% CI, 0.80-0.88; P < .001) and cancer mortality (HR, 0.87; 95% CI, 0.81-0.94; P < .001). Aspirin use 3 or more times per week was associated with decreased risk of mortality of all causes (HR, 0.81; 95% CI, 0.80-0.83; P < .001), any cancer (HR, 0.85; 95% CI, 0.81-0.88; P < .001), GI cancer (HR, 0.75; 95% CI, 0.66-0.84; P < .001), and CRC (HR, 0.71; 95% CI, 0.61-0.84; P < .001). When stratified by BMI (calculated as weight in kilograms divided by height in meters squared), aspirin use 3 or more times per week among individuals with BMI 20 to 24.9 was associated with reduced risk of all-cause mortality (HR, 0.82; 95% CI, 0.78-0.85; P < .001) and any cancer mortality (HR, 0.86; 95% CI, 0.79-0.82; P < .001). Among individuals with BMI 25 to 29.9, aspirin use 3 or more times per week was associated with reduced risk of all-cause mortality (HR, 0.82; 95% CI, 0.79-0.85; P < .001), any cancer mortality (HR, 0.86; 95% CI, 0.81-0.91; P < .001), GI cancer mortality (HR, 0.72; 95% CI, 0.60-0.86; P < .001), and CRC mortality (HR, 0.66; 95% CI, 0.51-0.85; P = .001).

CONCLUSIONS AND RELEVANCE:

In this cohort study, aspirin use 3 or more times per week was associated with a reduction in all-cause, cancer, GI cancer and CRC mortality in older adults.

It looks like all women need to be assessed for risk of breast cancer so that high-risk women can be offered medications to reduce risk. James W. Mold, MD, MPH

IMPORTANCE:

Breast cancer is the most common nonskin cancer among women in the United States and the second leading cause of cancer death. The median age at diagnosis is 62 years, and an estimated 1 in 8 women will develop breast cancer at some point in their lifetime. African American women are more likely to die of breast cancer compared with women of other races.

OBJECTIVE:

To update the 2013 US Preventive Services Task Force (USPSTF) recommendation on medications for risk reduction of primary breast cancer.

EVIDENCE REVIEW:

The USPSTF reviewed evidence on the accuracy of risk assessment methods to identify women who could benefit from risk-reducing medications for breast cancer, as well as evidence on the effectiveness, adverse effects, and subgroup variations of these medications. The USPSTF reviewed evidence from randomized trials, observational studies, and diagnostic accuracy studies of risk stratification models in women without preexisting breast cancer or ductal carcinoma in situ.

FINDINGS:

The USPSTF found convincing evidence that risk assessment tools can predict the number of cases of breast cancer expected to develop in a population. However, these risk assessment tools perform modestly at best in discriminating between individual women who will or will not develop breast cancer. The USPSTF found convincing evidence that risk-reducing medications (tamoxifen, raloxifene, or aromatase inhibitors) provide at least a moderate benefit in reducing risk for invasive estrogen receptor-positive breast cancer in postmenopausal women at increased risk for breast cancer. The USPSTF found that the benefits of taking tamoxifen, raloxifene, and aromatase inhibitors to reduce risk for breast cancer are no greater than small in women not at increased risk for the disease. The USPSTF found convincing evidence that tamoxifen and raloxifene and adequate evidence that aromatase inhibitors are associated with small to moderate harms. Overall, the USPSTF determined that the net benefit of taking medications to reduce risk of breast cancer is larger in women who have a greater risk for developing breast cancer.

CONCLUSIONS AND RECOMMENDATION:

The USPSTF recommends that clinicians offer to prescribe risk-reducing medications, such as tamoxifen, raloxifene, or aromatase inhibitors, to women who are at increased risk for breast cancer and at low risk for adverse medication effects. (B recommendation) The USPSTF recommends against the routine use of risk-reducing medications, such as tamoxifen, raloxifene, or aromatase inhibitors, in women who are not at increased risk for breast cancer. (D recommendation) This recommendation applies to asymptomatic women 35 years and older, including women with previous benign breast lesions on biopsy (such as atypical ductal or lobular hyperplasia and lobular carcinoma in situ). This recommendation does not apply to women who have a current or previous diagnosis of breast cancer or ductal carcinoma in situ.

In patients with heart failure with reduced ejection fraction (<40%), guideline-directed medical therapy (GDMT) is recommended to reduce sudden cardiac death and all-cause mortality; GDMT includes β-blockers; mineralocorticoid receptor antagonists; and angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, or angiotensin receptor–neprilysin inhibitors (class I, level A recommendation).
In patients with left ventricular ejection fraction (LVEF) of 35% or less due to ischemic heart disease at least 40 days after myocardial infarction, at least 90 days after revascularization, and with New York Heart Association (NYHA) class II or III heart failure despite GDMT, an ICD is recommended if expected survival is greater than 1 year (class I, level A recommendation).
In patients with LVEF of 30% or less due to ischemic heart disease at least 40 days after myocardial infarction, at least 90 days after revascularization, and with NYHA class I heart failure symptoms despite GDMT, an ICD is recommended if expected survival is greater than 1 year (class I, level A recommendation).
In patients with nonischemic cardiomyopathy, NYHA class II to III symptoms, and LVEF of 35% or less despite GDMT, an ICD is recommended if expected survival is greater than 1 year (class I, level A recommendation).
