TL;DR: Serum prostate specific antigen levels do not reflect tumor burden and pathological stage accurately in individual patients for 2 reasons: 1) the unpredictable contribution from the benign prostatic hyperplasia component of the gland and 2) the decreasing production of prostatespecific antigen by higher grade lesions as tumor volume increases.

TL;DR: Serum prostate specific antigen measurements may be helpful in stage A1 cancer patients with levels of 1 ng/ml. or less, or greater than 10 ng./ml.
