To predict prostate cancer outcomes, doctors currently rely on measures that suggest how far the tumour has spread and how abnormal the cancer cells appear under the microscope. Another common method is the use of blood tests to look for a marker called prostate specific antigen (PSA), although some men with prostate cancer do not have a raised PSA level and some men with a raised PSA do not have prostate cancer. And for every 100 men with a raised PSA, only about a third will have any cancer cells in their prostate.
Now, US researchers at the Fox Chase Cancer Center say there may be a better marker to indicate when a man has a more aggressive form of prostate cancer. Checking for a protein called MDM2 could improve current testing methods which are less than perfect.
