ACG Updates Colorectal Cancer Screening Guidelines

In their new colorectal screening guidelines, the American College of Gastroenterology, says that colonoscopy, beginning at age 50 and performed every 10 years, is the “preferred” screening test for colorectal cancer.  They recommend that physicians first offer this test alone rather than a menu of options. However, if patients are not willing to have a colonoscopy, they support offering: Preferably. a cancer prevention test: Either flexible sigmoidoscopy every 5 to 10 years  or CT colonography every 5 years. A test primarily for cancer detection: Preferred test is fecal immunohistochemical test for blood (FIT). They further recommend that African Americans begin testing at 45 rather than 50.

What's the Risk of Cancer after Polyps are Removed?

Five years after a colonoscopy found and removed polyps, one in ten patients will have a new advanced polyp and six in every thousand will be diagnosed with colorectal cancer. Pooling studies that followed up nearly 10,000 men and women who had a polyp removed during a colonoscopy (polypectomy), researchers found 1,082 with a later advanced adenoma and 58 with colorectal cancer.  Median follow-up time was 47 months.

North Carolina Gastroenterologists Offer Free Colonoscopies

Digestive Health Specialists, located in Winston-Salem NC, will provide free screening colonoscopies to 50 people impacted by the economic turndown.  Patients who are over 50, have not been screened, and  have lost jobs and health insurance are eligible to apply. Colonoscopies will be performed in Digestive Health Specialist facilities in Winstom-Salem, Kernersville, and Thomasville on March 14, 2009.  The program is part of March Colorectal Cancer Awareness Month.

Quality Standards Key for Colonoscopies Says AGA

It’s important to have standards for quality colonoscopy and to be sure that quality measures are included in doctors’ reports after each procedure. In light of the recently published study showing colonoscopy impact on deaths from colorectal cancer, the American Gastroenterological Association (AGA) points out the value of documenting and reporting key indicators for a quality colonoscopy after every procedure.

Colonoscopies Not Perfect in Stopping Colorectal Cancer Deaths

The percentage of colorectal cancer deaths prevented by colonoscopy may be overestimated. While still very effective in preventing colorectal cancer and deaths from the disease, limits of the test may be larger than previously thought.  Patients need to know that having colonoscopy does not guarantee that they won’t get colorectal cancer. Experts now say that screening colonoscopy may reduce death from colorectal cancer by 60 to 70 percent and may not keep patients from dying from cancers on the right side of their colons at all. A new Canadian study found that some people who died of colorectal cancer had a colonoscopy in the years before their cancer diagnosis.  A

Finding Polyps Missed During Colonoscopies for Lynch Syndrome

Lynch syndrome (also known as hereditary nonpolyposis colon cancer) greatly increases the risk for colon and rectal cancer. People with the gene have about an 8 in 10 chance of getting colon cancer during their lives. Because Lynch cancers develop quickly and grow rapidly, it’s important to monitor people who carry the genes closely with colonoscopy every year or two. When doctors in four research centers immediately followed up Lynch syndrome patients after a regular colonoscopy with more intense colonoscopy scrutiny, they discovered they had missed more polyps than they found.  During the first exam, their miss rate for adenomas, polyps with the greatest risk of developing into cancer, was

Positive FOBT Should Trigger Colonoscopy

Even if a patient had a previous clear colonoscopy or all polyps seen on that exam were removed, a new positive fecal occult blood test (FOBT) calls for a repeat colonoscopy. After 21,600 clear colonoscopies done at the Veterans Administration Medical Center in Phoenix, 57 patients needed a second colonoscopy after they had a positive FOBT for blood in their stool. Of those one-third (19) had a newly discovered adenomatous polyp and 3 had colon or rectal cancer.  One in four of the new adenomas were advanced.

Improved Colonoscope Finds More Polyps

Doctors using a new optical device mounted on the end of their scopes, found significantly more polyps in the colon during routine colonoscopies.  Called the Third Eye Retroscope™, it lets gastroenterologists see both forward and backward as the scope moves through the colon. Although colonoscopy is extremely sensitive and will discover most colon polyps during an exam, some are missed.  They may be hidden in the back side of folds in the colon wall or not seen because they are outside of the half circle view of the standard colonoscope.   The wider view allowed doctors to find 13 percent more polyps and 10 percent more adenomatous polyps, the ones more
