RT Journal Article SR Electronic T1 Chemoprevention of colorectal cancer: Slow, steady progress JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 346 OP 350 VO 70 IS 4 A1 Burke, Carol A. A1 Bauer, William M. A1 Lashner, Bret YR 2003 UL http://www.ccjm.org/content/70/4/346.abstract AB In population-based observational studies, people had lower rates of colorectal cancer if they were taking various agents, including nonsteroidal anti-inflammatory drugs, calcium, and folate. In placebo-controlled trials in patients with familial adenomatous polyposis and in patients with sporadic colon adenomas, nonsteroidal anti-inflammatory drugs reduced the rates of adenomas, and there is a biologic rationale that they would be effective in reducing colorectal cancer as well. Randomized trials of chemopreventive agents are underway in the general population.
