Race, Income, and Survival in Stage III Colon Cancer: CALGB 89803 (Alliance).

ABSTRACT:

Background

Disparities in colon cancer outcomes have been reported across race and socioeconomic status, which may reflect, in part, access to care. We sought to assess the influences of race and median household income (MHI) on outcomes among colon cancer patients with similar access to care.

Race was self-reported by 1116 White and 90 Black patients at study enrollment; MHI was determined by matching 973 patients' home zip codes with publicly available US Census 2000 data. Multivariate analyses were adjusted for baseline sociodemographic, clinical, dietary, and lifestyle factors. All statistical tests were 2-sid
