PSA doubling time in this group of patients does not play a primary role. Q. Are you suggesting that the standard definition most people use, based on two or three data points, is probably not reliable?
Conduct a transrectal ultrasound to find the prostate volume by measuring the length, width and height of the prostate. Multiply these numbers together and multiply the result by 0.52 to find the prostate volume. Divide the PSA test number by the size of the prostate gland found during the transrectal ultrasound to find the PSA density. For instance, if a patient has a PSA test of 6.0 ng/ml and a prostate volume of 40 ml, divide 6.0 by 40. 6.0/40 = 0.15. Evaluate the results of the PSA density for numbers of 0.15 or higher, lessening the likelihood that the elevated PSA test came from a benign growth, according to Cookson.
