Still, screening research continues, in the hopes that some lifesaving benefits may be found. Now the latest study once again casts doubt on PSA screening as an effective public health tool. British scientists divided more than 400,000 men between the ages of 50 and 69 into two groups: one was screened for prostate cancer with a single PSA test Introduction. Serum prostate-specific antigen (PSA) was deemed a viable tumor marker for the detection of prostate cancer (PCa) allowing clinicians to track patient response to cancer treatment. 1 However, initial investigations into PCa usually involve a combination of digital rectal examination (DRE) and measurement of PSA levels. Based on these measurements a referral for Transrectal Sensitivity analysis of studies at lower risk of bias (n=1) also demonstrates that screening seems to have no effect on all-cause mortality (IRR 1.0, 0.98 to 1.02; moderate certainty) the recent Cluster Randomised Trial of PSA Testing for Prostate Cancer (CAP),10 which randomised over 419 357 men at 573 primary care practices in Prostate-specific antigen (PSA), also known as gamma-seminoprotein or kallikrein-3 (KLK3), P-30 antigen, is a glycoprotein enzyme encoded in humans by the KLK3 gene.PSA is a member of the kallikrein-related peptidase family and is secreted by the epithelial cells of the prostate gland in men and the paraurethral glands in women.. PSA is produced for the ejaculate, where it liquefies semen in We compared the placebo and finasteride groups for sensitivity and AUC of PSA for the detection of all prostate cancer, of Gleason grade 7 or higher prostate cancer, and of Gleason grade 8 or higher prostate cancer. All statistical tests were two-sided. Results: Of 5112 men in the placebo group, prostate cancer was detected in 1111. Gleason Background. For men without a diagnosis or symptoms of prostate cancer who, after being informed of the benefits and harms of testing, wish to undergo regular PSA testing, the following strategy is recommended because it is associated with reduced risk of death from prostate cancer: offer PSA testing every 2-4 years from age 50 to age 69, and offer further investigation if the PSA is greater Setting the sensitivity at 8095%, PHI had greater specificity for distinguishing prostate cancer on biopsy compared with PSA or percentage free PSA . The blood level of PSA is often elevated in men with prostate cancer, and the PSA test was originally approved by the US Food and Drug Administration in 1986 to monitor the progression of An elevated level of PSA may indicate a problem with the prostate. The PSA test uses a blood sample to measure your PSA level. In some patients, the PSA test may be used for prostate cancer screening. The PSA test also helps diagnose prostate cancer and noncancerous prostate disease and monitor if you have been diagnosed with these conditions.
