New Prostate Cancer Test Makes Diagnosis from Urine in 20 Minutes With Near 100% Accuracy, Researchers Say


Korean medical scientists have used learning from artificial intelligence to create a new prostate cancer screening test with nearly 100% accuracy.

The breakthrough, which is a simple urine strip, is likely to revolutionize testing, as existing methods are not only inaccurate, but can result in overdiagnosis and require invasive biopsies.

The current method is a PSA test, which stands for “prostate specific antigen” and which evaluates the levels of this particular protein in the blood. This test can have a misdiagnosis rate of up to 80%.

This is because PSA is produced from both cancerous and non-cancerous prostate cells, and even if the test detects cancerous PSA, there is a risk that it is diagnosing tumors that would never produce symptoms for a lifetime. according to the Mayo Clinic.

Additionally, other conditions such as inflammation of the prostate, infection, or an enlarged prostate can also mislead a standard PSA test, leading to the prescription of an invasive biopsy that can cause bleeding and pain.

Designed at the Korea Institute of Science and Technology, the breakthrough, led by chief scientist Dr. Kwan Hyi Lee, created a urine test strip containing an ultrasensitive biosensor based on electrical signals and introduced AI analysis to quantify the values. of four separate prostate cancer factors.

PLUS: A new simple blood test for prostate cancer determines the presence and stage of the cancer with 99% accuracy

The AI ​​then uses an algorithm to determine whether or not they add to cancer. This process led to an accuracy rate greater than 99% in 76 different tests.

“For patients who need surgery and / or treatments, the cancer will be diagnosed with high precision using urine to minimize unnecessary biopsies and treatments, which can dramatically reduce medical costs and fatigue of medical staff,” he said Professor Gab Jeong, who assisted Dr. Lee on the project, in a statement according to Phys.

Prostate cancer is the most common variety in men, and millions of people around the world lose their lives each year from it. Like other medical procedures, sometimes a patient may feel embarrassed by a particular diagnostic method and may choose not to get one as a result, which could certainly be the case with invasive biopsies.

The invention of a simple urine strip has the added benefit of being able to be done in private, and combined with the super-accurate results, the test seems like a field change.
