New Urine Test Detects Prostate Cancer Better Than Other Methods, Study Suggests. An experimental biomarker test developed by researchers at the University of Michigan more accurately detects prostate cancer than any other screening method currently in use, according to a study published in the February 1 issue of Cancer Research, a journal of the American Association for Cancer Research.
The researchers say a simple urine test that screens for the presence of four different RNA molecules accurately identified 80 percent of patients in a study who were later found to have prostate cancer, and was 61 percent effective in ruling out disease in other study participants. This is far more accurate than the PSA blood test currently in use worldwide, which can accurately detect prostate cancer in men with the disease but which also identifies many men with enlarged prostate glands who do not develop cancer, researchers say.
Chinnaiyan believes that any tests that are developed and widely tested would first be used to supplement a PSA blood screen. Genes Increase Prostate Cancer Risk. Prostate cancer may not be at the top of your list of topics for dinner conversation with Dad. But you might reconsider: About 10% of prostate cancer cases are linked with family history, and evidence for the disease's genetic roots is growing. Researchers have recently identified a series of gene markers that, when present with family history of the disease, increase a patient's risk of prostate cancer more than nine times. Those markers, say researchers, can be detected in a simple saliva or blood sample — good news for a condition whose prognosis is improved by early detection.
In a study published online today by the New England Journal of Medicine (NEJM), a team of American and Swedish researchers reported the results of a DNA analysis of over 4,700 Swedish men. The study found that patients whose genes contained four of the five common variants, found to be associated with prostate cancer in 2006 and 2007, had a 400% to 500% increased risk of developing the disease.
