Doctors can now detect hard-to-diagnose prostate cancer
Date:8/8/2012

NEW YORK (August 9, 2012) -- Researchers have successfully developed and tested a new prostate cancer screening method that uses the combined power of a novel drug therapy and changes in PSA levels over time to identify men with a high PSA who are more likely to have aggressive prostate cancer despite negative biopsies.

The new study by researchers at NewYork-Presbyterian Hospital/Weill Cornell Medical Center, published in the Journal of Urology, shows that PSA can be a much more effective marker for prostate cancer when an additional drug therapy is used than it can as a stand-alone test, which is how it is currently used by physicians.

"At a time when the value of PSA is being increasingly debated, we have shown that when used in a specific way, it can be of great value in identifying men with previously undetected prostate cancer," says the study's lead investigator, Dr. Steven A. Kaplan, the E. Darracott Vaughan Jr., Professor of Urology at Weill Cornell Medical College and director of the Iris Cantor Men's Health Center at NewYork-Presbyterian/Weill Cornell.

"We have shown that using PSA with these drugs can help us differentiate prostate cancer from benign prostate disease in patients who are difficult to diagnose," says Dr. Kaplan, who is also chief of the Institute for Bladder and Prostate Health at NewYork-Presbyterian/Weill Cornell. "It also demonstrates a better way to use both the PSA test and these powerful drugs."

Dr. Kaplan created the combination screening method as a way to understand cancer risk in men who have consistently abnormal PSA readings despite one or more negative biopsies. This patient population offers physicians a "diagnostic dilemma" he says -- "despite the fact that biopsies are becoming more and more effective at detecting cancer in the prostate, a significant number of patients with prostate cancer continue to have negative biopsies." He adds that the PSA (prostate specific antig
