ACS Seeks 500,000 for Long-term Cancer Study

Posted: April 30, 2007
The American Cancer Society this week launched a major new cancer research effort that aims to enroll 500,000 people.

According to the society, the study may be the "last best chance" to do large-scale research in the United States on genetic, lifestyle and environmental factors that cause and prevent cancer.

The Cancer Prevention Study 3 (CPS-3) will seek a geographically and ethnically diverse group of women and men, aged 30 to 65, who have never been diagnosed with cancer. The participants will be tracked for 20 or more years.

"There are no U.S. studies on the horizon positioned to take advantage of rapidly developing new knowledge and technologies over the coming decades, except CPS-3," study leader Eugenia E. Calle, managing director of analytic epidemiology at the American Cancer Society, said in a prepared statement.

"This type of study involves hundreds of thousands of people, with diverse backgrounds, followed for many years, with collection of biological specimens and assessments of dietary, lifestyle and environmental exposures. It also requires active follow-up to discover if and when study participants develop cancer," Calle said.
