Are there any specific risk factors for gastric cancer that are more prevalent in Hispanic communities compared to other ethnic groups?
Dr. Jun Gong:
So this is an interesting question in terms of risk factors and certain ethnic groups. We’ve realized that actually gastric cancer is highly prevalent in East Asia. And there, the risk factors seem to be more diet-related. But then when you look on the Western side of the world, it’s different risk factors that exist for stomach cancer. You always have familial risk. These are genetic, ancestral, or hereditary causes of stomach cancer, which are fairly rare. And this is independent of geography.
But here on the West, we tend to see more of risk factors related to the Western lifestyle. Here, gastritis or chronic gastritis, heartburn, longstanding inflammation is a risk factor. Heavy smoking, heavy alcohol use, and obesity are emerging risk factors for stomach cancer as well. And also, we have a very unique risk factor in a bacteria called H. pylori that is known globally to be a risk factor for gastric cancer.
And we’ve done research on this in that although the demographics in the U.S. is very diverse, we do see that Asians and Hispanics and African Americans compose higher risk groups for stomach cancer when compared to non-Hispanic whites. And in certain ethnic groups such as the Koreans, it can be as much as five times the risk for non-Hispanic whites. And we think it is due to these unique variations in H. pylori risk across the different races. We’ve done research at Cedars-Sinai where we’re looking at the Hispanic population and we’ve seen over time that actually, in addition to Hispanic populations being at higher risk for stomach cancer, it seems to be affecting a younger group and in particular younger females.
So we’re looking into this kind of new epidemiologic evidence as to why stomach cancer in Hispanics is becoming younger in onset and tends to have a predilection for females. And these patients however, if they are afforded the correct treatment and the timely treatment, their outcomes are just as good as the non-Hispanic counterparts. So this is an emerging topic and a very important topic in my opinion.
