[Quantitative changes of testosterone and prostate-specific antigen at low and high densities of PSA in men with prostate cancer].

In 61 patients with prostate cancer quantitative changes of testosterone and prostate-specific antigen (PSA) in blood serum at low and high densities of PSA have been investigated. It was shown that a high coefficient of correlation has been established in patients with prostate cancer and low density of PSA, but weak correlation was documented for the patients with prostate cancer and high density of PSA.
