In the past, research staff have received Progression Letters or contacted the STAMPEDE trial team to obtain this value. Laura J. Martin

Rather, it is the change in PSA levels over time. 04/10/2008 PSA .05 It is used as a tool to help determine a man's risk of having a positive biopsy for prostate cancer if he has a “normal” value.

A PSA level greater than that expected for the patient’s age does not necessarily mean carcinoma – but certainly warrants further evaluation by an urologist.

PSA Velocity - Shiny App. If you are a patient, print the PSA Doubling Time Worksheet and bring it with you to your next appointment.

Users of the prediction tools should not rely on information provided by the prediction tools for their own health problems.

Basically, PSA velocity is the rate at which your PSA level increases from year to year.

In the past, research staff have received Progression Letters or contacted the STAMPEDE trial team to obtain this value. It will now take values generated by the ultra sensitive PSA tests.

Privacy Policy. Subcategory of 'Diagnosis' designed to be very sensitive Rule Out. PSA velocity is a measurement that takes into account annual changes in PSA values, which rise more rapidly in men with prostate cancer than in men without prostate cancer.

The prostate-specific antigen (PSA) velocity is not a separate test.

Use of the prediction tools does not create an express or implied physician-patient relationship. From: What does it mean when the doubling time comes up negative? This PSA density calculator is an easy tool which enables you to evaluate your PSA density - an important indicator of prostate cancer in patients with a mildly elevated PSA. With PSA velocity, what matters is a significant change over time, and for this to be accurate, you need to have multiple PSA measurements taken in the same laboratory, because PSA measurements can vary slightly from lab to lab.

Reviewed Even when the total PSA value isn't higher than 4, a high PSA velocity (an increase greater than 0.75 ng/mL in one year) suggests that cancer may be present and a biopsy should be considered.

Memorial Sloan Kettering Hospital publishes, on the web, a prostate cancer calculator that among other things can calculate PSA doubling time and PSA velocity. When else is the prostate-specific antigen test used? While a change in PSA over time is often considered to be of greater concern than the absolute level of PSA, the role of this test in screening for prostate cancer is still uncertain. Read more.

MRC Clinical Trials Unit at UCL90 High Holborn2nd FloorLondonWC1V 6LJ, Independent Data Monitoring Committee (IDMC), For the purposes of the STAMPEDE trial, a unique threshold PSA value for biochemical failure is calculated for each patient, referred to as the PSA progression value. Let's say you have the following PSA values over time: January 2008: 1.4 ng/ml January 2009: 1.9 ng/ml January 2010: 1.9 ng/ml January 2011: 3.1 ng/ml April 2011: 3.6 ng/ml Then what is your PSA… We're committed to providing you with the very best cancer care, and your safety continues to be a top priority. Natural history of progression after PSA elevation following radical prostatectomy. If patients have already started ADT prior to randomisation, the first LHRH injection must have been given within 12 weeks prior to randomisation in order to be eligible for the STAMPEDE trial.

The PSA Doubling Time Calculator calculates rate of PSA doubling in prostate cancer (correlates with survival). Of the 5,519 men in the placebo arm, PSA velocity usage would have led to 548 (almost 10% of the study population) additional biopsies, 433 (79%) of which would have been negative. 02/10/2008 PSA .04 See http://www.mskcc.org/applications/nomograms/Prostate/PsaDoublingTime.aspx, For example, if you use my current PSA numbers which are: Call us to schedule an appointment or contact us online. 1999 May 5;281(17):1591-7. doi: 10.1001/jama.281.17.1591. additional information. The calculator can be used by going to: PSA stands for perfect sensitivity approximation, and to find this value would normally require some annoying math, but there is a PSA method calculator that you can use online that streamlines the process and makes it much more manageable.
