USC scientists help identify genetic markers for prostate cancer in global DNA download
Share

An international team of researchers including USC scientists has found scores of new genetic markers in DNA code that increase prostate cancer risk — powerful knowledge likely to prove useful to detect and prevent the disease.

Focusing on DNA of more than 140,000 men worldwide, researchers were able to identify 63 new genetic markers associated with prostate cancer risk. That greatly increases the number of genetic risk regions, bringing the total to more than 170 and moving scientists closer to using genetic information for clinical treatment.

The results will help bridge the gap between cancer research diagnosis and treatment, equipping physicians with tools to screen at-risk patients. The study, based at USC with collaborators worldwide, including the London-based Institute of Cancer Research, was published today in Nature Genetics.

“This is not a cure, but the information can help to identify men at high risk of developing prostate cancer who may benefit from enhanced screening and future targeted prevention,” said Christopher A. Haiman, professor of preventive medicine at the Keck School of Medicine of USC and a principal investigator for the project.

Prostate cancer is the second-most common cancer in American men, with one in nine men being diagnosed in
