Improving outcomes in breast cancer: where should we target our efforts?

Abstract

Rural-urban differences in health outcomes, including breast cancer, in the US have been studied for decades, but often with inconsistent findings. Possible reasons include methodological differences, lack of prospective investigations, small number of studies overall, and the tendency to measure rurality as a simple patient-level predictor variable. Studies have tended to assume that the same racial/ethnic cancer disparities found in the general population exist in rural regions, but this conclusion may not always be warranted. Needed are better definitions of rurality; the capability to define important predictor variables such as race, ethnicity, education, and income with greater precision than at present; and data revealing the patient’s own perspective regarding care decisions. Future studies should examine whether the impact of rurality status on outcomes varies with geographic location by including the appropriate interaction terms in the outcome prediction models, as well as patient-reported reasons that might explain the outcomes observed.
