Minorities At Higher Risk for Gastric Cancer

Non-white are a disproportionately higher risk gastric cancer compared to non-Hispanic white Americans, and this was specially true among Asian Americans.

This population-based study demonstrated that non-white race and ethnic groups had a several-fold higher risk of developing compared to the non-Hispanic white population. The disproportionate odds were most pronounced among Korean Americans age 50 and older, who exhbited a 12-fold to 14.5-fold higher risk compared to non-Hispanic whites. This is the most common location for stomach cancer to develop. However, Asian Americans — with the exception of Japanese American men — had a lower risk than non-Hispanic whites of developing gastric cancer in the upper portion of the stomach where it joins the esophagus (cardia gastric cancer).

“We specifically chose to analyze individuals age 50 years and older since this is the age group for whom average-risk colorectal cancer screening and high-risk esophageal cancer screening is recommended,” said Shailja Shah, MD, MPH, assistant professor of Medicine, the study’s lead author and corresponding author in a press release.

 

“Unfortunately, even though certain ethnic groups have rates of gastric cancer that even exceed colorectal cancer, and even though gastric cancer is more common than esophageal cancer, screening for gastric cancer does not yet occur in the United States among high-risk groups. We are hopeful that the findings of this study will break the inertia surrounding gastric cancer screening”
