The PSA test is a serum lab test for prostate-specific antigen.If the test value is elevated,the patient is at risk for carcinoma of the prostate;a PSA value greater than 10 ng/ml is highly suggestive of prostatic carcinoma.Tissue from a transrectal prostate biopsy provides the cellular information to confirm the diagnosis.The American Urological Association (AUA)prostate cancer staging tool essentially provides what important information about the tissue specimen?

The American Urological Association (AUA)recommends that starting at age 40 the prostate-specific antigen (PSA)test and digital rectal examination (DRE)be offered to men at average risk.Clinical evaluation and an elevated PSA usually indicate the need for a transrectal ultrasound needle biopsy to confirm the diagnosis.When the results of the biopsy are positive for cancer,the AUA score measures the severity of the cancer:stage A = clinically unsuspected disease;stage B = tumor confined to the prostate gland;stage C = tumor localized to the periprostatic area;stage D = metastatic prostate cancer.
