July 18, 2016 — U.S. government agencies and their colorectal cancer prevention have set a goal that at least 80 percent of adults ages 50-75 will be screened for colorectal cancer. A recently published study conducted by researchers at the Centers for Disease Control and Prevention (CDC) shows that the U.S. healthcare system has the capacity to make this goal a reality.
To determine if the U.S. could expand its screening capacity, CDC researchers used mathematical modeling to estimate the number of colonoscopies or fecal immunochemical tests (FIT) that would be necessary every year to screen for colorectal cancer for 80 percent of adults in the recommended age group. They found that 5.1 million to 13 million colonoscopies would need to be conducted per year, depending on which screening test was first used.
The analysis also used survey data from facilities that perform colonoscopies to determine the number of colonoscopies that are performed in the U.S. every year — and to calculate how many more they could do. This survey showed that 15 million colonoscopies were performed in the U.S. in 2012, and that another 10.5 million colonoscopies could be performed every year.
“Colorectal cancer is the second leading cancer killer for men and women in the U.S., but it doesn’t have to be,” said Djenaba Joseph, M.D., MPH, medical director of the colorectal cancer control program at CDC and lead author of the paper. “Screening saves lives. The good news is that our modeling shows that the U.S. healthcare system has the potential to meet our national goal of screening 80 percent of adults ages 50-75. Ask your doctor about screening — there are several options now.”
Of the cancers affecting both men and women, colorectal cancer (cancer of the colon or rectum) is the second-leading cancer killer in the U.S., according to the CDC. Screening can find precancerous polyps — abnormal growths in the colon or rectum — so they can be removed before turning into cancer. Screening also helps find colorectal cancer at an early stage, when it is easier to treat.
The U.S. Preventive Services Task Force (USPSTF) recently reinforced its recommendations that adults ages 50-75 be screened for colorectal cancer. This recommendation continues to receive USPSTF’s highest rating — an “A” grade, indicating that the evidence is convincing that screening for colorectal cancer has substantial benefits. But only a little more than half of the target population is up-to-date with screening.
The new study, “Colorectal Cancer Screening: Estimated Future Colonoscopy Need and Current Volume and Capacity,” is published online in the journal Cancer.
