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 ...

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 ...

We conducted a systematic review of studies published before March 2007 in which a PSA dynamic (velocity or doubling time) was calculated in patients before definitive treatment, a subsequent event ...

Serum PSA values >4.0 ng/ml are routinely used to select patients for prostate biopsy, although this approach misses some early-stage cancers. Some researchers advocate dropping the PSA threshold to 2 ...

Arnhem, November 2009 – The November issue of European Urology, the official journal of the European Association of Urology, features an article focussing on prostate specific antigen (PSA) velocity ...

Elevated serum prostate-specific antigen (PSA) levels can indicate the presence of prostate cancer, although PSA levels are also elevated in some nonmalignant conditions, which affects the reliability ...

PSA blood test Compared with absolute PSA, PSA velocity associated more with increased likelihood of progression among men on active surveillance for prostate cancer. PSA velocity (PSAV) is associated ...

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 ...

Cancer organizations commonly recommend prostate biopsies for men who have experienced a rapid rise in PSA levels. But according to findings from a San Antonio study published Feb. 24 in the Journal ...

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

Prostate cancer is much more likely to kill if a man’s PSA level rises rapidly before the cancer is even diagnosed, according to a study that suggests a new and far more meaningful way of looking at ...
