A new blood test used in combination with a conventional prostate-specific antigen (PSA) screening sharply increases the accuracy of prostate cancer diagnosis, and could eliminate tens of thousands of unneeded, painful, and costly prostate biopsies annually, according to a study led by researchers at Dana-Farber Cancer Institute.
At the annual meeting of the American Society of Clinical Oncology in Orlando, Fla., William K. Oh, M.D., and Robert W. Ross, M.D., will report that the six-gene molecular diagnostic test, when combined with a PSA test, accurately detected prostate cancer more than 90 percent of the time. Earlier studies suggest that the conventional PSA test is 60-70 percent accurate in detecting cancer.
The findings will be discussed at a poster session on Sunday, May 31, 8-11 a.m., Level 2, W230A.
