Researchers cautioned that their study did not examine adenomas and CRC in elderly Caucasian patients, so study findings for minorities cannot be compared to the Caucasian population or their accompanying risk factors.

Prevalence of Colorectal Neoplasia in Asymptomatic Hispanics Undergoing Screening Colonoscopy (Abstract #S1558)
Although cancer rates among Hispanics are typically lower than those among non-Hispanic whites, the prevalence of colonic adenomas (benign tumors) and neoplasia (tumor formation) in Hispanics is similar to that of non-Hispanic whites, according to new research from the University of Puerto Rico Cancer Center.
Studying 647 patients ages 50 and older undergoing colorectal cancer (CRC) screening at a large private gastroenterology practice in Puerto Rico (PR Gastroenterology Institute), researchers found that males were two times more likely to have colorectal neoplasia than women, and were more likely to have multiple polyps compared to women. They also found that patients older than 60 had a 56 percent greater chance of having polyps than those under age 60.
Marcia Cruz-Correa, MD, PhD, associate professor of medicine and biochemistry at the University of Puerto Rico Cancer Center, and study co-author Fernando Ramos, MD, also found that the location of the polyps in Hispanics differed from where they are typically found in non-Hispanic Caucasians: of the patients who had polyps, 70 percent were on the proximal or right side of the colon. Dr. Cruz-Correa attributed the difference in location to underlying molecular differences in the two populations.
"Colorectal cancer screening rates among Hispanics are dangerously low," said Dr. Cruz-Correa. "Currently, only 40 p
