Researchers closing in on possible cancer vaccine

    And not like the HPV vaccine, either.<blockquote>A cancer vaccine with a twist is making headway in clinical trials at the University of Pittsburgh School of Medicine. Rather than targeting a cancer-related virus--the way Gardasil targets human papillomavirus to prevent some cervical cancers--the new vaccine triggers the immune system to attack a faulty protein that's often abundant in colorectal cancer tissue and precancerous tissue.

    The Pitt investigators say that if the vaccine is successful, it could potentially obviate the need for repeated colonoscopies in patients at high risk for developing colorectal cancer. These patients have had multiple precancerous polyps, called advanced adenomas, in their intestines, and they are routinely screened by colonoscopy for signs of recurrence.

    The vaccine has already proven safe in patients with advanced pancreatic cancer. It is now in clinical trials to gauge the immune response it elicits in patients with a history of advanced adenomas. It works by spurring the body to manufacture antibodies against the abnormal version of a mucous protein called MUC1. While moderate amounts of the protein are found in the lining of normal intestines, high levels of a defective form of MUC1 are present in about half of advanced adenomas and the majority of colorectal cancers.

    The vaccine primes the immune system to monitor the gut for emerging cancers by teaching it to recognize abnormal MUC1. If an adenoma develops and begins to produce the faulty version of MUC1, the immune system will raise antibodies to attack and destroy the precancerous tissue. . . .

    Using this kind of immunotherapy to combat cancer isn't new--a number of cancer vaccines are currently being tested in clinical trials. But so far the technique has been used only to attack existing tumors. The new vaccine represents the first attempt to use immunotherapy to keep cancer from forming in the first place.</blockquote>http://www.technologyreview.com/biomedicine/23067/

    Even though this isn't a magic bullet, this is still pretty freakin' amazing.

    This would be pretty good news if it pans out. As someone who has lost many loved ones to cancer, I live for the day when we can kick this despicable disease to the curb once and for all.

    I hereby humbly propose that anyone who has profited from decrying science and/or technology be forbidden from receiving this vaccine, by Constitutional amendment if necessary.

    I'm down for anything that would prevent me from having a colonoscopy sometime in my life.
