Abstract
|
|
|
We measured the concentration of serum PSA and prostatic acid phosphatase for studying the usefulness of PSA in 145 cases with BPH and 24 cases with prostate cancer. PSA was more sensitive and same specific as PAP in diagnosis of prostate cancer
(n≤20
ng/ml). The diagnostic accuracy and positive predictive predictive rate of PSA were higher than PAP, positive predictive rate was highest in PSA(n≤10 ng/ml) with abnormal digital rectal examination. PSA was a simple and useful method for
detection
of
prostate cancer. But, by strict statistical criteria alone, PSA by itself didn't qualify as an effective screening tool. By combination with digital rectal examination and transrectal ultrasonography, it may be useful in early detection of
prostate
cancer.
