Polyp Prevention Trials

Colorado collaborates with other cancer centers in the conduct of trials to test the effects of various nutrients and medications on reduction of risk for colorectal cancer. We have conducted several such trials in past years, testing effects of aspirin, calcium, and folic acid. Studies are now underway to test the effects of daily selenium supplements on polyp formation. (PI Dennis Ahnen, funded by NCI)

The Selenium and Vitamin E Clinical Trial is an ongoing large trial across the country, in which daily supplements of selenium and/or vitamin E are being tested to reduce the risk of prostate cancer. Colorado is one of the largest of the clinical centers for this trial. (PI David Crawford, funded by NCI)
