Comparative access to and use of digital breast tomosynthesis screening by women's race/ethnicity and socioeconomic status.
This study looked at access to digital breast tomography (DBT) versus regular mammography and whether women of minority race/ethnicity and lower socioeconomic status experienced lower DBT access during the early adoption period and persistently lower DBT use over time. This cross-sectional study included 92 geographically diverse imaging facilities across 5 US states, with over 2.3 million screening examinations performed among women aged 40 to 89 years from January 1, 2011, to December 31, 2017. Data were analyzed from June 2019, to August 2020. Women who used DBT increased for all women from 3.3% in 2011 to 82.6% in 2017. In 2012, Black, Hispanic, Asian American, and women with less than a high school education had lower DBT access compared to White women attending the same facility and also college graduates. Lower DBT access continued over time regardless of the number of years after facility-level DBT adoption.

National distribution of cancer genetic testing in the United States: evidence for a gender disparity in hereditary breast and ovarian cancer.
Identifying mutation carriers is critical for treatment decisions, cancer prevention, and early detection. This study analyzed the 2015 US National Health Interview Survey (NHIS), a cross-sectional in-person interview gathering self-reported health data for the US population. The study found that while cancer genetic testing seems to reach a broad geographic and sociodemographic population in the national survey, there remain underrepresented groups, including Hispanics, the uninsured, noncitizens, and those with less education.

Association between out-of-pocket costs, race/ethnicity, and adjuvant endocrine therapy adherence among Medicare patients with breast cancer.
This study aimed to determine whether there are racial/ethnic differences in 1-year adherence to adjuvant endocrine therapy (AET) and whether out-of-pocket costs explain the racial/ethnic disparities in adherence. It concluded that racial/ethnic disparities in AET adherence were largely explained by women's differences in socioeconomic status and out-of-pocket medication costs.

Risks of developing breast and colorectal cancer in association with incomes and geographic locations in Texas: a retrospective cohort study.
This study aimed to determine whether median household income was associated with the risk of developing breast and colorectal cancer in Texas and to identify higher cancer risks by race/ethnicity and geographic areas. It demonstrated that higher income was associated with an increased risk of breast cancer and a decreased risk of colorectal cancer in Texas.

Cost-effectiveness of chemotherapy for breast cancer and age effect in older women.
The researchers assessed the cost-effectiveness of chemotherapy regimens by age and disease stage under "real-world" conditions for patients with breast cancer. They found that anthracycline-based chemotherapy was found cost-effective for elderly patients with early stage (stage I, II, IIIa) breast cancer considering the US threshold of $100,000 per QALY.

Racial/Ethnic and socioeconomic disparities in endocrine therapy adherence in breast cancer: a systematic review.
The authors sought to understand factors that influence endocrine therapy (ET) adherence among racial/ethnic and socioeconomic subpopulations of breast cancer patients. They found significant underuse of ET among minority and low-income women. They further noted that both race/ethnicity and socioeconomic status are associated with ET use in most settings.

Socio-demographic and geographic variations in the utilization of hormone therapy in older women with breast cancer after Medicare Part-D coverage.
The researchers assessed socio-demographic, geographic, and other variations in the receipt of hormone therapy among patients with hormone receptor-positive breast cancer as well as adherence to hormone therapy within 1-year follow-up. They found that found that increasing age was significantly associated with a decreased receipt of hormone therapy and aromatase inhibitors in all hormone receptor-positive breast cancer patients after adjusting for other factors regardless of whether chemotherapy was received.

CMF-regimen preferred as first-course chemotherapy for older and sicker women with breast cancer: findings from a SEER-Medicare-based population study.
This study aimed to determine the utilization of Cyclophosphamide, Methotrexate, and 5-Fluorouracil (CMF) as first-course chemotherapy in recent years, and identify the sociodemographic and clinical characteristics associated with its prescription. It found that older and sicker women, living in census tracts with lower average education, and diagnosed with advanced stage, hormone receptor-negative tumors have a higher probability of CMF administration.
