40% in US skip life-saving colon screenings

U. PITTSBURGH (US) — A new study offers the strongest evidence to date that screening reduces colorectal cancer deaths and prevents people from getting the disease.

Published online in the New England Journal of Medicine, the study indicates that colorectal cancer screening is effective at preventing cancer from developing in the left and right colon, and also prevents death.

“Colorectal cancer screening is effective because we’re not just searching for cancer. We’re identifying the precursors of cancer, colorectal polyps, and removing them. By doing so we are preventing cancer from developing,” says Robert Schoen, professor of medicine and epidemiology at the University of Pittsburgh and lead author of the study. “It’s the ultimate public health success story.”

Results from the study also were presented at the Digestive Disease Week 2012 conference.

Colorectal cancer is the second-leading cause of cancer death in the United States, with more than 50,000 people dying from the disease each year. Progress has been made in reducing incidence and death rates from the disease, thanks in part to screening, but there is potential for an even greater reduction.

For the study, which began in 1993, 154,900 men and women from the ages of 55 to 74 were randomly assigned to screening with flexible sigmoidoscopy with a repeat screening at three or five years, or to “usual care,” which means whatever screening they might receive in routine medical care with their physician.

Over 86 percent of the subjects underwent a screening exam. Most subjects with abnormal sigmoidoscopy screening results then had a full colonoscopy. Overall, the screening resulted in a 21 percent reduction in cancer incidence and 26 percent decline in colorectal cancer deaths. There was a 50 percent reduction in death due to distal colon cancer, the portion of the colon that can be directly examined by the flexible sigmoidoscopy exam.

“There is still room for improvement. Our biggest obstacle is the underutilization of screening,” Schoen says. “Right now, 40 percent of the US population is not getting screened, and we know screening works. We need to encourage everyone to undergo screening to save themselves from this potentially deadly disease, and to reduce the unnecessary public health burden and expense of colorectal cancer.”

This study was funded by the National Institutes of Health’s National Cancer Institute.

    In regards to underutilization of screening: the cure should not be worse than the cancer.
    First, the prep – cleansing the colon for two days with sugar/artificial sweetener water is very unhealthy for the colon and the person. So the health care professionals need to come up with a better way to do that.
    Secondly, they should focus on finding out how to prevent polyps in the first place so this distasteful procedure won’t be necessary.

    My husband and I at age fifty decided together to get colonoscopy screening, it seemed like the responsible thing to do. We made an appointment and then got a call. Our insurance wouldn’t cover it, and the cost would be 3,000.00. Each.
    It wasn’t hard to talk us out of an unpleasant procedure, that we had no symptoms for, that cost 6,000.00.

    My mom aged 82, healthy all her life, is now dying of rectal cancer because she never had the screening colonoscopy despite being encouraged, indeed begged, by her daughter, a nurse. It is important for the public to know that the treatment of the cancer,which is preventable, involves colostomy, or an opening of the bowel higher on the abdomen, which requires careful and regular care. This is the key to getting people to get the screening. If you knew what was involved with the treatment of this disease(radiation, chemo, surgery, more chemo, more surgery and life altering daily care), two days of bowel prep and a painless procedure is a no-brainer.

    THINK AGAIN ABOUT THE CONSEQUENCES OF BEING IN THE 40%!
