Urine test may help predict prostate cancer risk

A new urine test might help doctors detect prostate cancer and better evaluate a patient’s treatment options, researchers say. The test looks for two genetic markers associated with prostate cancer. The first, called TMPRSS2:ERG, is caused by two genes changing places and fusing together; it is thought to cause prostate cancer. Since the gene fusion is only seen in about half of cancer patients, the test also looks for another marker, called PCA3.

For the study, published in the Aug. 3 issue of Science Translational Medicine, Tomlins’ team studied urine samples from 1,312 men who had high PSA levels and had had a prostate biopsy or surgery to remove the prostate. The researchers specifically looked for the two markers and used them to slot the men into high-, intermediate- or low-risk groups for prostate cancer. They then compared their results with the results from biopsies, which are done with a needle in a physician’s office for detection of any cancer cells. Read more…
