Description:Background:
Limited population-based studies have focused on breast cancer survivors in rural populations. We sought to evaluate the risk of adverse health outcomes among rural and urban breast cancer survivors and to evaluate potential predictors for the highest risk outcomes.
Methods:
A population-based cohort of rural and urban breast cancer survivors diagnosed between 1997 and 2017 was identified in the Utah Cancer Registry (UCR). Rural breast cancer survivors were matched on year (±1 year) and age at cancer diagnosis (±1 year) with up to 5 urban breast cancer survivors (2,359 rural breast cancer survivors; 11,748 urban breast cancer survivors). Cox proportional hazards models were used to calculate hazard ratios (HRs) with 99% confidence intervals (CI) for adverse health outcomes overall, within 5 years, and >5 years after cancer diagnosis.
Results:
Compared to urban breast cancer survivors, rural breast cancer survivors had a 39% (HR = 1.39, 95%CI 1.02, 1.65) higher risk of heart failure (HF) within the 5 years of follow-up. Overall, there was no increase in the risk of other adverse health outcomes. A higher baseline body mass index and Charlson Comorbidity Index, family history of cardiovascular diseases, family history of breast cancer, and advanced cancer stage were risk factors for HF for rural and urban breast cancer survivors, with similar levels of HF risk.
Conclusions:
Rural residence was associated with an increased risk of HF among breast cancer survivors.
Impact:
Our study highlights the need for primary preventive strategies for rural cancer survivors at risk of heart failure.
