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 ...

Measurement of PSA velocity (PSAV) is often used in preference to PSA for the early detection of prostate cancer, but how much additional predictive information PSAV provides is unclear. Yu et al.

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" ...

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 ...

If you need further proof that medicine is just as much art as science, a new study shows that some common sense needs to prevail before rushing into possibly unnecessary prostate biopsies if there is ...

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" ...
