Abstract: | Purpose: Disparities in health outcomes due to a diagnosis of colorectal cancer (CRC) have been reported for a number of demographic groups. This study was conducted to examine the outcomes of late‐stage diagnosis, treatment, and cancer‐related death according to race and geographic residency status (rural vs urban). Methods: This study utilized cross‐sectional and follow‐up data from the Surveillance, Epidemiology, and End Results (SEER) Program for all incident colon and rectal tumors diagnosed for the Atlanta and Rural Georgia Cancer Registries for the years 1992‐2007. Findings: Compared to whites, African Americans had a 40% increased odds (OR, 1.40; 95% CI, 1.30‐1.51) of late‐stage diagnosis, a 50% decreased odds (OR, 0.50; 95% CI, 0.37‐0.68) of having surgery for colon cancer, and a 67% decreased odds (OR, 0.33; 95% CI, 0.25‐0.44) of receiving surgery for rectal cancer. Rural residence was not associated with late stage at diagnosis or receipt of treatment. African Americans had a slightly increased risk of death from colon cancer (HR, 1.11; 95% CI, 1.00‐1.24) and a larger increased risk of death due to rectal cancer (HR, 1.24; 95% CI, 1.14‐1.35). Rural residents experienced a 15% increased risk of death (HR, 1.15; 95% CI, 1.01‐1.32) due to colon cancer. Conclusions: Further investigations should target African Americans and rural residents to gain insight into the etiologic mechanisms responsible for the poorer CRC outcomes experienced by these 2 segments of the population. |
