Overweight and obese men have lower PSA values, even before they get prostate cancer
Date:2/19/2008

DURHAM, N.C. -- Men who are overweight or obese have lower concentrations of prostate-specific antigen (PSA) in their blood than their normal-weight counterparts, according to a new study led by Duke University Medical Center researchers.

The finding echoes earlier results on PSA concentrations found in obese and overweight men with prostate cancer and highlights the need to reconsider PSA threshold values for heavier patients, and to encourage those patients to get serious about losing weight.

A study released last year from our group showed that obese and overweight men with prostate cancer had deceptively low PSA scores compared to normal-weight men with prostate cancer, but we now have extended our findings to show that this trend holds true in the general screening population, said Marva Price, R.N., a family nurse practitioner and researcher in Dukes School of Nursing, the Duke Comprehensive Cancer Center and the Duke Prostate Center..

We found that mildly obese mens PSA scores were fourteen percent lower than normal-weight men, and moderately and severely obese men had 29 percent lower PSA values, Price said.

Doctors have proposed that overweight and obese men have lower PSA scores because their bodies have a greater volume of blood. Larger blood volumes dilute the amount of PSA in the bloodstream, making the concentration of PSA -- which is what is measured to screen for prostate cancer -- lower.

The latest results appear online in the Feb. 9, 2008 issue of the journal Urology. The study was funded by the United States Department of Defense.

PSA is considered the gold standard for detecting prostate cancer; it is a protein released into the blood by the prostate gland, and is elevated in the presence of cancer.

For this study, researchers looked at PSA scores among 535 men who took part in a free prostate cancer screening program. Seventy-three percent of the group was overweight or obese.
