How accurate is the 4k test for prostate cancer?

A test, known as the 4Kscore, could help from 30- to 58-percent of men could avoid an unnecessary prostate cancer biopsy. It has been shown to reliably predict the likelihood of a man’s prostate cancer spreading to other parts of his body in the next 20 years.

What is a 4k test for prostate?

The 4Kscore® Test (OPKO Lab, Nashville, TN) is a new blood test that accurately identifies the risk of aggressive prostate cancer; it plays an important clinical role as a reflex test prior to proceeding with initial prostate biopsy in men with an elevated PSA level or abnormal digital rectal examination results.

What is normal 4k score?

A PSA level of 4.0 ng/mL and lower is considered normal, while a PSA level above 4.0 ng/mL is considered elevated and may indicate an enlarged prostate (typical in older men) or prostate cancer. Recent studies recommend using less than 2.5 or 3 ng/mL as a cutoff for normal values, particularly in younger patients.

What is the 4k score for prostate cancer?

The 4Kscore® Test result provides you and your physician with your risk of high-grade, aggressive prostate cancer (Gleason 7 or higher) if a prostate biopsy were to be performed.

How reliable is the 4Kscore test?

Unlike traditional PSA tests, 4Kscore distinguishes men with a low risk for aggressive prostate cancer from those with a high risk. Men with a low-risk 4Kscore have a more than 99 percent chance of not developing distant metastasis within the next 10 years.

What is a high 4Kscore?

The higher this number, the lower your chance of having aggressive prostate cancer upon biopsy. For the 4Kscore, aggressive disease is defined as a diagnosis greater than or equal to Gleason 7 prostate cancer.

What does a high 4Kscore mean?

The 4Kscore® Test provides an assessment of a patient’s risk for aggressive prostate cancer (Gleason 7 or higher) if a prostate biopsy were performed. Patients with an elevated 4Kscore® result should be considered for further evaluation and treatment.

How accurate is the 4k test?

The 4Kscore provides a percent risk (ranging from 1-95%) of a patient having aggressive prostate cancer on biopsy. This is computed using several different factors (described below). This test has been shown to be far more accurate than PSA in determining if a patient may have aggressive prostate cancer.

How much does a 4k score test cost?

What you should not do before a PSA test?

Before having a PSA test, men should not have ejaculated during the previous 48 hours. Semen released during sexual activity can cause PSA levels to rise temporarily, which may affect the test results. For the same reason, before having a PSA test men should not have: exercised vigorously in the previous 48 hours.

Is a Gleason score of 8 bad?

A Gleason score of 7 is considered medium-grade cancer and Gleason 8 and above is high-grade cancer. The lower the Gleason score, the less likely the cancer is going to spread to the lymph nodes, bones or other organs.

How much does a 4Kscore test cost?

The 4KScore test costs $395; PCPT is free. The “widely used” PCPT was chosen for the study because it is the “best comparator” and uses clinical values to “ascertain high-risk prostate cancer,” said Dr.

Will the prostate cancer 4kscore test help you?

Hi Donald, the 4K Score test is only beneficial for men who have NOT had prostate cancer. It is a good screening to tool for such patient. The PSA test is actually a very good test for men after prostate cancer treatment to assess recurrence of cancer.

What is a 4 K prostate test?

The 4Kscore test combines four prostate-specific kallikrein assay results with clinical information in an algorithm that calculates the individual patient’s risk for aggressive prostate cancer. According to developer OPKO Lab, the test has undergone extensive clinical development and confirmation.

What is the best test for prostate screening?

There is no standard screening test for prostate cancer. Researchers are studying different tests to find those with the fewest risks and most benefits. One test is the digital rectal exam (DRE).
