- Percent Free Prostate-Specific Antigen: Entering a New Era in . . .
The introduction of prostate-specific antigen (PSA) testing into clinical medicine in 1986 revolutionized the management of patients with prostate cancer The major limitation of this tumor marker stems from its inability to provide a clear distinction between benign prostate disease and prostate cancer, especially in patients with upper limit of normal or slightly increased PSA values Recent
- Free total PSA ratio is a powerful predictor of future . . .
Men with PSA levels of 4 1 to 10 ng mL who are not suspected of having prostate cancer by whatever means should undergo %fPSA measurement and be carefully monitored at short intervals over the long-term if they have lower %fPSA levels
- Normal PSA Levels (PSA Level 4,5,6,7,8,9) Explained
Is an indicator of prostate cancer (25% chance, according to the ACS), or other benign condition in the elderly such as benign prostate hyperplasia (BPH), or just inflammation of the prostate Free PSA blood test is required for confirmation whether it’s a cancer or not

- Prostate-specific antigen screening for prostate cancer . . .
Prostate specific antigen (PSA) has transformed the diagnosis and treatment of prostate cancer by enabling early detection at global scale Due to expression in both benign and malignant cells, PSA-based prostate cancer screening using single cut-points yields imperfect diagnostic performance and has led to the detection and over-treatment of low-grade prostate cancer
- Interpreting the PSA - the key to adequate prostate cancer . . .
Although it is not yet known why there is a smaller fraction of free PSA in the serum of prostatecancer patients, Dr Catalona and others believe that measuring free PSA can reduce unnecessary biopsies by 25 to 35 percent or more, depending on the size of the gland, and still detect 90 percent of cancers
