Ivanhoe, 10/21/09
A team of Northwestern University researchers has detected previously undetectable levels of prostate–specific antigen in patients who have undergone a radical prostatectomy. Thanks to the power of the nanoparticle–based bio–barcode assay, the researchers found measureable PSA in each post–operative patient in the study. The technology is 300 times more sensitive than commercially available PSA tests. After the removal of the prostate gland, patients typically have PSA levels that are undetectable when measured using conventional tools. This new tool may enable doctors to diagnose men with prostate cancer recurrence years earlier than is currently possible.
