Prostate Specific Antigen (PSA)

Prostate-Specific Antigen (PSA) Test

• Prostate-specific antigen (PSA) is a protein produced by cells of the prostate gland. The PSA test measures the level of PSA in the blood (see Question 1). • The U.S. Food and Drug Administration (FDA) has approved the use of the PSA test along with a digital rectal exam to help detect prostate cancer in men age 50 and older. The FDA has also approved the PSA test to monitor patients with a h...

Clinical Use of Prostate Specific Antigen ( PSA )

Like other countries, Japan is recording a rapid increase in the incidence of prostate cancer. The use of serum PSA (prostate specific antigen) measurement as a blood marker for prostate cancer has become widespread. Higher levels of PSA are associated with a higher probability of a diagnosis of prostate cancer. Needle biopsies detect prostate cancer in 20–30% of cases with PSA levels of 4.1–10...

PRODUCTIO N OF PROSTATE-SPECIFIC ANTIGEN (PSA) BY A BREAST CANCER CELL LINE, SK-Br-3

PSA is a 33-KDa serine protease that is produced predominantly by prostate epithelium. However, it has been shown that about 30-40% of female breast tumors produce PSA and its production is associated with the presence of estrogen and progesterone receptors. We have now developed a new tissue culture system to study PSA production in breast cancer and its association with prognostic factors...
