By Leslie Harris O’Hanlon This last year has seen a surge of activ-ity in researching and developing tests to help clinicians better diagnose and treat prostate cancer. Better tests are needed, many say, to more accurately detect prostate cancer and to help men and their physicians decide what to do about it. A few such tests have become commercially available recently or are poised to do so. But researchers warn that the tests need to pass muster before being adopted for use in the clinic.“They need to be proven,” said Scott A. Tomlins, MD, Ph. D., assistant professor of pathology and urology at the University of Michigan at Ann Arbor.“This is an important consideration for clinicians to have: How much does this test improve their clinical decision making, and what will they do with the results of the test?”
