New PSA test could improve the way we detect prostate cancer

CINCINNATI (WKRC) - A new test in the works could help better identify men who are at high risk of prostate cancer.

Local 12 talked to the the cancer team at St. Elizabeth Healthcare to find out more about this new test. It's called an IsoPSA, and it has the potential to reduce the number of unnecessary biopsies performed.

The traditional PSA is based on a concentration in the blood. It can be high due to everything from an enlarged prostate to an infection. The IsoPSA, however, is structural-based, which means if it's used in addition to the traditional test and other discussions of family history, medical professionals hope they can better identify patients at risk of prostate cancer.

The IsoPSA test was the subject of a recent report by the Cleveland Clinic. Since many men get biopsies where no cancer is discovered, they were looking at the IsoPSA and a better-directed biopsy -- an MRI instead of an ultrasound-guided biopsy.

Dr. Pratish Shah says with those two parameters, they found they are more successful in identifying high-risk prostate cancer patients.

He points out this test is still in research and development and it is not available for individual patients, but he said it would add one more potential tool to allow patients to get the proper diagnosis and future treatment.

This information is based on a study in the journal Urology. There's no word on how soon the new IsoPSA might be on the market.
