The study shows that lower normal PSA improves prostate cancer detection. The American Cancer Society's ongoing National Prostate Cancer Detection Project recommends further tests for patients with a PSA...
Prevalence of Prostate Cancer Among Men with Normal PSA LevelsProstate CancerNew England Journal of Medicine
6,7,8. Indeed, 21% of men with positive end of study biopsies enrolled in the Prostate Cancer Prevention Trial (PCPT) had serum PSA levels between 2.6 and 3.9 ng/mL and 15.4% of the tumors found in men with PSA levels < 2.5 ng/mL were high grade cancers9. The PSA test for ...
Serum prostate-specific antigen (PSA) is currently the most used biomarker in clinical practice for prostate cancer (PCa) detection. However, this biomarker has several drawbacks. In this work, an untargeted gas chromatography-mass spectrometry (GC-MS)-based metabolomic profiling of PCa cells was ...
aPSA is used clinically to track prostate cancer growth in humans, and in normal cancer progression, the rate of PSA increase tends to accelerate with time. PSA在人临床用于跟踪摄护腺癌成长,并且在正常癌症进步, PSA增量的率倾向于加速以时间。[translate]...
The clinical and pathological features of metastatic prostate cancer with normal level of serum prostate-specific antigen (PSA) were investigated. Four patients with metastatic prostate cancer had serum PSA within the normal range at the diagnosis. All tumors were poorly-differentiated adenocarcinoma. End...
A PSA level above 4.0 ng/mL in any age group must be investigated. However, PSA levels can spike in noncancerous conditions, such as benign prostate hypertrophy (BPH), urinary tract infections, prostatitis, consumption of testosterone supplements, recent catheterization, and injuries to the pelvic...
PSA Tests The prostate gland produces a protein called prostate specific antigen (PSA). Most of the PSA is removed from the body with semen, but some of it ends up in the bloodstream. Normally, this is a very small amount that is either free floating or bound to other substances. ...
