More Likely to Be Presented With Emergency Colorectal Cancer Diagnosis Are African-Americans And Economically Disadvantaged Populations

According to data, 29 percent of patients with colorectal cancer in a nationally representative sample were diagnosed after an emergency, such as an obstruction or perforation of the bowel. The data was presented at the 11th Annual AACR International Conference on Frontiers in Cancer Prevention Research, held here Oct. 16-19, 2012. In addition, African-Americans and those living in high-poverty areas were more likely to present with an emergency diagnosis.

"Overall, there are high rates of emergency presentation of colorectal cancer in the United States," said Sandi L. Pruitt, Ph.D., M.P.H., assistant professor in the department of clinical sciences at The University of Texas Southwestern Medical Center in Dallas. "Screening for colorectal cancer using tests including colonoscopy is recommended for all healthy, asymptomatic adults starting at age 50. But these high rates of emergencies indicate that there are multiple missed opportunities for screening. As a result, many patients are not diagnosed until they have an emergency, such as an obstruction or perforation of the bowel, which leads to more complications and a higher risk for death from cancer."

Pruitt and colleagues evaluated disparities in emergency colorectal cancer presentation using nationally representative Surveillance Epidemiology and End Results-Medicare data from 1992 to 2005 of U.S. adults aged 66 and older with invasive colorectal cancer.

They identified 88,859 patients with colorectal cancer, and of those, 29 percent presented as emergencies. Of these, 81.3 percent had an emergency admission, 31.6 percent were obstructions and 4.2 percent were perforations. In unadjusted analyses, African-American patients with colorectal cancer were 64 percent more likely to present as emergency cases, and those patients with colorectal cancer living in census tracts with the highest poverty rate (greater than or equal 20 percent versus less than 10 percent poverty) were 31 percent more likely to present as emergencies.

After researchers statistically controlled for multiple factors including cancer stage, patient health status and sociodemographic factors, African-Americans were 29 percent more likely to present with emergency cases, and those living in census tracts with the highest poverty rate were 10 percent more likely to present with emergency colorectal cancer.

"We already know that African-Americans and economically disadvantaged populations face an increased risk for death from colorectal cancer," Pruitt said. "In future research, we will attempt to understand how emergency presentation of colorectal cancer contributes to racial and economic disparities in death from colorectal cancer."

Funding sources for this study include the Cancer Prevention Research Institute of Texas, the National Cancer Institute and the National Center for Research Resources.
