URO TODAY: The benefits of prostate-cancer screening compare favourably to other cancer screening programmes (breast, cervical), say Swedish researchers who have studied 20,000 men over 14 years. READ MORE>

This study (of PSA testing) shows that prostate cancer mortality was reduced almost by half over 14 years.

However, the risk of over-diagnosis is substantial and the number needed to treat is at least as high as in breast-cancer screening programmes.

NEW PROSTATE CANCER INFOLINK: The PSA test is far from accurate as a screening tool for large numbers of otherwise healthy men at no specific risk for prostate cancer, according to a new study by Swedish researchers. READ MORE>

“…it would seem clear to us that PSA testing is (as Stamey suggested some years ago) no longer as useful as it may initially have been in predicting risk for clinically significant prostate cancer.

Even though the specificity of the PSA test for prostate cancer still seems to be reasonably high at PSA levels between 3 and 5 ng/ml, the sensitivity of the test is poor, and PSA values below 1.0 ng/ml “virtually ruled out a prostate cancer diagnosis during the follow-up.”

This group of authors state very clearly that, “Additional biomarkers for early detection of prostate cancer are needed before population based screening for prostate cancer should be introduced.”

This does not mean that we should not continue to use the PSA tests until we have better biomarkers, but it does suggest that as a screening tool for large numbers of otherwise healthy men at no specific risk for prostate cancer, the PSA test is far from accurate.
