A new study by the University of Kentucky’s Markey Cancer Center highlights the need for increased access and education to reduce disparities in colorectal cancer screening in Black communities.

According to the Qualitative research published in Journal of Cancer Educationpeople in Kentucky’s Black community may not be aware of all colorectal diseases cancer Screening options are available to them, especially stool-based tests.

Black communities are disproportionately affected by colorectal cancer In Kentucky, blacks with colorectal cancer are more likely to die from the disease than whites.

As about half of the mortality from black and white colorectal cancer can be explained by the disparity in screening rateEducating Black communities about screening options can save lives, says researcher Aaron Kruse-Diehr, Ph.D., the study’s principal investigator.

Kruse-Diehr, who says: “In the world of colorectal cancer screening, we like to say that ‘the best test is the one the patient completes’—and giving people more choices has been shown in previous studies to increase their likelihood of completing screening”. is an associate professor at the University of Medicine. “To reduce colorectal cancer mortality among blacks and whites, we need to ensure that screen-age Blacks are provided with all available options.”

Regular screenings starting at age 45 are key to colorectal cancer prevention and early detection. There are two types of tests recommended by the U.S. Preventive Services Task Force: visual examination (primarily endoscopy) and stool-based testing to examine stool for signs of cancer. Stool-based tests are less invasive and, for many people, more accessible because they can be done at home.

“At-home testing can reduce some of the individual and structural barriers that often exist for many people to completing a colonoscopy, such as the need to take time off work, finding an individual to get the person to/from the procedure, and the distance traveled to a provider who can perform the endoscopy,” says Kruse-Diehr.

The team partnered with five Black churches in Louisville, an area of ​​Kentucky with high black-and-white screening disparities, to conduct focus groups exploring screening barriers and advocates for cancer outreach and education.

Although most focus group participants recognized the importance of updating screening information, nearly all of them reported that they had never heard of stool-based tests or already health care provider offer them as an option for colorectal cancer screening.

To address this knowledge gap, participants emphasized community-based outreach and communication from trusted individuals, such as Black health providers in local and colorectal cancer survivors.

Kruse-Diehr led the study with Elizabeth Holtsclaw, director of strategic partnerships in support of cancer at the American Cancer Society. Two of the study’s co-authors, Carlee Combs and Rose Wood, students at the College of Public Health, helped analyze the data and write the results as part of an undergraduate independent research course. have their advisor.

The team is currently planning to pilot a church-based screening program with one of the partner churches, with the hope of eventually expanding the program across Kentucky.

“These research results are informative outreach efforts which we hope will make a big dent in mortality due to colorectal cancer among black Kentuckians,” Kruse-Diehr said.
