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 ...

According to data from a recent analysis, PSA dynamics, specifically PSA velocity and doubling time, did not improve the predictability of patient outcomes among men undergoing radical prostatectomy.

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 ...

We need better ways to determine which prostate-specific antigen (PSA)-detected localized prostate cancers are most likely to progress. The rate at which the PSA level rises (i.e., PSA velocity) prior ...

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 ...

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 ...

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 of prostate cancer when the tumor is still ...

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" ...

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 ...

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 ...

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 ...

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" ...
