Trends in surgical treatment of early-stage breast cancer reveal decreasing mastectomy use between 2003 and 2016 by age, race, and rurality.
The authors sought to examine trends in the surgical treatment of breast cancer by age, rurality, and among Black women in a populous, racially diverse, state in the Southeastern United States of America. Using data from the North Carolina Central Cancer Registry, they found declining mastectomy rates in the early 2000s in a Southern US state with a racially and geographically diverse population. These decreasing trends were consistent among key subgroups affected by cancer inequities, including Black and White rural women.

Evaluating travel distance to radiation facilities among rural and urban breast cancer patients in the Medicare population.
This study characterizes the actual distance older breast cancer patients traveled to radiation treatment and the minimum distance necessary to reach radiation care, and examines whether any patient demographic or clinical factors are associated with greater travel distance. Findings showed that patients living in rural areas traveled on average nearly 3 times as far as those from urban areas, and their nearest facility was more than 4 times farther away. Older age, being single or widowed, and lower household income were significantly associated with shorter actual travel distance, while increasing rurality was significantly associated with greater actual and minimum travel distance to radiation treatment.

Effects of program scale-up on time to resolution for patients with abnormal screening mammography results.
Effects of geographic program expansion to rural areas on mammogram screening program outcomes are understudied. The authors of this study sought to determine whether time-to-resolution (TTR) varied significantly by service delivery time period, location, and participant characteristics across 19 North Texas counties.

Differences in Medicare expenditures between Appalachian and nationally representative cohorts of elderly women with breast cancer: an application of decomposition technique.
The objective of this study was to determine Medicare expenditures during the initial phase of care among women in West Virginia (WV) who were Medicare beneficiaries with BC and compare them with national estimates. It found that the difference in average Medicare expenditures between the elderly beneficiaries with BC from a rural state (WV) and their national counterparts narrowed but remained significantly lower after multivariate adjustment.

Assessing local capacity to expand rural breast cancer screening and patient navigation: an iterative mixed-method tool.
To expand rural breast cancer screening , the researchers proposed a regional hub-and-spoke model, partnering with local providers to expand access across North Texas. Their capacity assessment tool enabled the hub to establish partnerships with county organizations by tailoring support to local capacity and needs.
