  • Methods for diagnosing benign prostatic diseases and prostatic adenocarcinoma using an algorithm
    Patent number: 6140065
    Abstract: The present invention relates to novel reflex methods for identifying a male human patient as suitable for diagnosis either benign prostatic diseases (BPD), (such as benign prostatic hyperplasia, prostatitis, or glandular atrophy), or prostatic adenocarcinoma (CAP) without requiring a biopsy. The method requires measuring two biochemical markers and knowing the patient age. The total prostate specific antigen (PSA) level in the blood or serum of the patient is measured. If the patient has a total PSA level of between 4.0 ng/mL and 20.0 ng/mL, then the free PSA level in the blood or serum of the patient is measured. The proportion of free PSA to total PSA is calculated. The patient's age is noted, rounding down to an integral numbers of years. The two measured values and the age are entered into a particular identifying algorithm which is derived from a logistic regression model. If a value of greater than about 0.
