- PSA Velocity and Doubling Time in Diagnosis and Prognosis of . . .
Conversely, there is good evidence that PSA velocity has no role for men with an untreated prostate; PSA velocity should not be used to recommend biopsy, determine eligibility for active surveillance versus curative treatment, or give prognosis as to the risk of post-treatment failure
- PSA Velocity and Clinical Progression in Low-Risk Prostate Cancer
Prostate-specific antigen testing is noninvasive, low risk, and readily obtained However, the clinical utility of PSA—in particular, PSA velocity (PSAV)—and its association with disease progression remain a focus of debate 1-5 Prostate-specific antigen velocity is the rate of PSA change over time Although some studies have demonstrated
- PSA Test: Purpose, Process, and What Elevated Levels Mean
A PSA velocity test measures how quickly PSA levels in the blood increase over time Elevated PSA velocity may warrant further evaluation for prostate cancer Your doctor may recommend a PSA velocity screening if you've been diagnosed with prostate cancer The test can help: Determine the effectiveness of a cancer treatment
- PSA Velocity: What It Reveals About Prostate Health
Studies have shown that a PSA velocity exceeding 0 75 ng mL per year is associated with a higher likelihood of prostate cancer, particularly aggressive forms requiring early intervention (Carter et al , 1992, JAMA) Cellular proliferation within the prostate plays a key role in PSA velocity
- PSA Velocity Does Not Improve Prostate Cancer Detection
In addition to receiving regular PSA tests and a prostate biopsy recommendation for PSA levels of 4 0 ng ml or higher, the majority of these men also underwent end-of-study biopsies irrespective of PSA levels As a result, the study authors wrote, “the PCPT provides a perfect test case for PSA velocity” throughout the entire range of PSA
- Understanding PSA Velocity and Why It’s Important for . . .
PSA velocity is calculated by measuring the change in PSA levels over multiple tests taken months apart For example, a man whose PSA levels rise steadily over the years may have a different risk profile than a man whose PSA levels suddenly spike quickly
- The utility of PSA velocity in prediction of prostate cancer . . .
Background: Prostate specific antigen kinetics (PSAK) including prostate specific antigen velocity (PSAV) and PSA doubling time (PSADT) are used as predictors of prostate cancer (PCa) therapeutic outcome, disease prognosis, and cancer-specific mortality However controversy persists regarding use of these parameters in cancer detection
- Prostate-specific antigen velocity in diagnosis and prognosis . . .
