Mayo clinic researching on colon cancer prevention strategies

Mayo clinic researching on colon cancer prevention strategiesMayo Clinic is participating in a study that is testing a new treatment that may stop polyps from returning.

The study is part of a five-year, $21.6 million colon cancer prevention program grant to the cancer center from the National Cancer Institute, the largest single program grant in the history of the Tucson-based center. Other institutions participating in the three-part program are Baylor University, University of Colorado, MD Anderson Cancer Center in Houston and the Translational Genomics Research Institute (TGen) in Phoenix. Other studies are looking at the epidemiological and lifestyle factors involved in colon cancer.

Mayo's part in the study springs from the preventive advantages of colon screenings.

"Colorectal cancer screenings are different," said Dr. Russell Heigh, the Mayo gastroenterologist in charge of Mayo's participation.

Mammograms and prostate screenings detect existing cancers. But finding a potential cancer before it strikes creates research opportunities in the area of prevention, Heigh said.

Heigh's research will focus on selenium as a possible cancer deterrent.

Other researchers are similarly examining the polyp-preventing traits of aspirin, folic acid and calcium, but the Arizona Cancer Center study is the only one in the country researching selenium.

Selenium is a dietary trace mineral that helps prevent cell damage by the oxidants that cause cancer. It is present in meats such as kidney and liver and in some grains and seeds.
