MedPage Today -- ORLANDO, June 2 -- A set of six genes, measured in a blood test, can be used to tell whether a man has prostate cancer, a researcher said here. In a case-control study, the six-gene panel outperformed a standard test -- age-adjusted prostate specific antigen -- in distinguishing between men with cancer and those without, according to Robert Ross, M.D., of Dana-Farber Cancer Institute in Boston.
