Abstract

Background: Individuals' communities impact cancer disparities and are intimately related to social determinants of health. Studies show that personal factors affect treatment refusals for a potentially curable cancer, but few studies have investigated whether community-based characteristics affect the receipt of surgery.

Methods: We used Surveillance Epidemiology and End Results Program registries from 2010 to 2015 to examine differences in rates of surgery refusal among non-Hispanic White, non-Hispanic Black, and Hispanic women diagnosed with nonmetastatic breast cancer. The community factor measures were based on county-level factors. Sociodemographic and community differences were analyzed using Pearson's χ2 tests and analysis of variance. Multivariate logistic regression of predictors of surgery refusal and the Cox proportional hazard model of disease-specific mortality were performed.

Results: Surgery refusers among non-Hispanic Black and Hispanic all races lived in counties with lower rates of educational attainment, median family and household income, and higher rates of poverty, unemployment, foreign-born, language isolation, urban population, and women more than 40 years old having mammography in last 2 years. Multivariate analysis shows surgery refusal rates increased in counties having a high percentage of urban population and declined in counties with an increased percentage of less than high school level education, unemployment, and median household income. Breast cancer-specific mortality increased significantly with surgery refusal.

Conclusion: Residence in counties with the lowest socioeconomic status and disproportionately populated by racial and ethnic minorities is associated with surgery refusal. Given the high mortality associated with refusing surgery, culturally sensitive education on the benefits of care may be appropriate.
