ACG: Racial Disparities Seen in Colorectal Cancer

WEDNESDAY, Oct. 28 (HealthDay News) -- Compared to other racial and ethnic groups, African-Americans have a significantly increased risk of developing colorectal cancer and receiving a diagnosis of late-stage disease, according to a paper presented at the American College of Gastroenterology Annual Scientific Meeting, held from Oct. 23 to 28 in San Diego.

Robert John Wong, M.D., of the California Pacific Medical Center in San Francisco, performed a retrospective cohort study of a large population-based cancer registry from 1973 to 2004.

Compared to Asian males, the author found that African-American males had a significantly higher incidence rate of proximal cancers per 100,000/year (25.2 versus 11.7). Compared to Asian females, he also found that African-American females had a significantly higher incidence rate (21.9 versus 11.4). Of all the groups studied, African-Americans had the highest incidence rates of advanced cancers. In both African-American males and females, the incidence rates were about double compared to those seen in Hispanic males and females.

"Significantly higher rates of advanced cancers among blacks and proximal cancers among females may represent disparities in health care access or sex-specific and race/ethnicity-specific variations in cancer biology," the author concludes. "Any future attempts to improve cancer prevention and screening programs should focus on interventions to address the disparities seen among these groups. Further research and programs to improve cancer screening would benefit from a targeted approach taking into account these sex-specific and race/ethnicity-specific cancer disparities."
