    New blood test could lead to the end of colonoscopies

    It can be a lifesaving test, yet more than a third of patients recommended for it fail to follow up. But the test called a colonoscopy may become history thanks to research by Alabama scientists.

    Researchers at Huntsville's HudsonAlpha Institute for Biotechnology announced today they've found measurable indicators in blood plasma that could identify patients with colon polyps. Left unremoved, polyps can develop into colon cancer, one of most common and potentially deadliest forms of cancer.

    Today, the accepted test for polyps is a colonoscopy, an expensive procedure where a specialist examines the colon with a camera. Cleaning out the bowels at home the night before the procedure is also one of the lesser pleasures of modern medicine. But colonoscopies that lead to removed polyps do save lives.

    Alabama doctor opens up about cancer and colonoscopy

    Dr. Herbert Chen, the head of surgery at UAB, turned 50 and became the public face of the hospital's campaign to screen for colon cancer.

    "A blood test that fulfills the role currently played by colonoscopies would have major positive impacts," Brian Roberts, a senior scientist in the Myers Lab at HudsonAlpha and lead study author, said today. "A lot of people joke about how they'd love to avoid the discomfort of colonoscopies," he said, "but there's a serious issue with people not actually getting screened."

    According to the American Cancer Society, only about 65 percent of adults 50 or older get colonoscopies when recommended by their doctors.

    The study that found the polyps indicator was published online last week in Clinical Cancer Research, a publication of the American Association for Cancer Research.

    HudsonAlpha researchers teamed with the University of Alabama in Birmingham School of Medicine to study a diverse group of men and women mostly over 50 years old. About 30 percent were African American, indicating the test works as well for men and women of African and European descent.

    In the test, the researchers studied blood plasma collected at UAB. The team focused on RNA found in the plasma and found that differences in some RNA molecules identified patients with colon polyps that could turn cancerous.

    'More work to do'

    "There's a lot more work to do before patients might see a test like this at the clinic, but we're optimistic that with more research and after clinical trials, eventually, we will see blood-based screening for colon polyps and colon cancer itself offered routinely to patients," Dr. Rick Myers said. Myers is president and science director at HudsonAlpha as well as a researcher.

    In addition to Roberts and Myers, HudsonAlpha researchers who worked on the study include Andrew Hardigan, Dianna Moore, Ryne Ramaker, Angela Jones, and Dr. Greg Cooper.

    The researchers collaborated with Dr. Robert Kimberly and Meredith Fitz-Gerald at the Center for Clinical and Translational Science at UAB; and Dr. C. Mel Wilcox, director of the Gastroenterology and Hepatology Division in the Department of Medicine at UAB.

    The research was funded by the State of Alabama, the Center for Clinical and Translational Science NIH grant at UAB, and an anonymous private donor.

    The thing that always bugged me about colonoscopies and insurance was, if they found nothing, you're covered, if they have to remove a polyp, you have to pay

    Huh? I thought the whole point was to find the little buggers before they did harm

    ???? I've been going for an annual colonoscopy and polyp snip and stitch for a decade or so because I'm great at growing polyps. My insurance (BCBS IL PPO) has always covered everything done in lower G.I. including removal of the polyps and lab studies thereof.

    Mine (done on the 10 year plan) has always been 100% covered as well. Various insurance companies. Never had a polyp yet.

    Is your deductible always met? My insurance pays 100% as long as it's "screening" but if a polyp is found it becomes "diagnoses" and it switches to where they pay IF deductible is met and then whatever your ins pays i.e. 80-20, 50-50, 100 , whatever.

    I think my insurance just charges one rate (80/20 after deductible) for all procedures, be they diagnostic or screening. That said, lucky me, I've had polyps with every single colonoscopy I've hadand I'm still too "young" for standard screening protocol, so maybe there is some 100% covered version that I don't know about. I went in the first time due to bleeding and go back when a year passes or bleeding reoccurs, whichever happens first.
