Prostate-specific antigen 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. In the study group, the serum levels of all forms of PSA increased at 1 st hour after ejaculation and returned to baseline at 24 th hours. Ejaculation induced a more pronounced increase in tPSA (10.5%) than in fPSA (9.9%) and in cPSA (4.3%). These increases were statistically significant for tPSA and fPSA. Consequently, 781 men needed to be invited for screening to avert one prostate cancer death, and 48 men needed to be biopsied. [ 10] At 16 years of follow-up, the prostate cancer mortality rate ratio was 0.80 (95% CI, 0.72-0.89), and the prostate cancer incidence rate ratio was 1.41 (95% CI, 1.36-1.45). Therefore, 570 men needed to be In the blood, PSA levels can be either free or bound to other molecules. That's why one suitable measure is the free/total PSA ratio. Achten, R., & van Kerrebroeck, P. (2010). A new algorithm in patients with elevated and/or rising prostate-specific antigen level, minor lower urinary tract symptoms, and negative multisite prostate Include foods rich in omega-3 fatty acids (e.g., cold-water fatty fish, walnuts, algae) Avoid or significantly limit certain foods and supplements (see "Reduce or avoid foods that harm the prostate") Choose prostate cancer-killing foods and supplements, such as tomatoes, green tea, and vitamin D. Stay well hydrated with pure water. Higher total PSA levels and lower percentages of free PSA are associated with higher risks of prostate cancer. Total prostate-specific antigen (PSA) and free PSA are performed and reported on every specimen. If the initial total PSA concentration is between 4.0 and 10.0 ng/mL, then the percent free PSA result will be calculated and reported .
