February 24, 2011 — A change in the level of prostate-specific antigen (PSA) — known as PSA velocity — is not a good predictor of prostate cancer. In fact, in the absence of other indications, such as ...

Using absolute prostate-specific antigen (PSA) thresholds to make decisions about diagnostic testing and biopsies remains controversial (Journal Watch Top Story Dec 31 2004), but PSA velocity (the ...

Some studies have suggested that the rate of change of prostate-specific antigen levels may correspond with prostate cancer survival. But this does not necessarily mean that PSA velocity will be ...

Preoperative PSA velocity is more useful than PSA doubling time for predicting outcomes after radical prostatectomy for prostate cancer, according to researchers. William J. Catalona, MD, of the ...

Getting your Trinity Audio player ready... Washington – How fast a man’s PSA level is rising – even before it’s high enough to trigger a doctor’s alarm – may signal that he has a life-threatening form ...

Unequivocal randomized trial data show that PSA velocity does not benefit decision making in localized prostate cancer. A recent paper suggests that the literature is wrong and that PSA velocity does ...

Prostate biopsies based on PSA changes are largely unnecessary, researchers say. Feb. 25, 2010— -- If prostate biopsies were based only on the rate of change in PSA level over time, the number of ...

Guidelines of several cancer organizations have recommended that men with a rapid rise in PSA have a biopsy for prostate cancer, even if there is no other indication and the PSA is within the "normal" ...

The most significant single predictor of aggressive prostate cancer is an elevated rate of increase in prostate specific antigen (PSA) levels, according to a new study. Published in the July 1, 2007 ...

To determine whether men at risk of death from prostate cancer, despite radical prostatectomy, can be identified at diagnosis on the basis of PSA velocity. Pretreatment and follow-up data on ...

NEW YORK, Nov. 10 (UPI) -- New York researchers suggest a rapidly rising prostate specific antigen may not indicate a greater risk of diagnosis of prostate cancer. A.J. Vickers of the Memorial ...

Guidelines of several cancer organizations have recommended that men with a rapid rise in PSA have a biopsy for prostate cancer, even if there is no other indication and the PSA is within the "normal" ...
