Student Develops New Technique For Diagnosing Prostate Cancer
An Undergraduate Chemistry Major student at the Missouri University of Science and Technology has developed a new technique for testing prostate cancer.
The technique works by detecting certain metabolites in urine samples. The metabolite can help to show the presence of prostate cancer. This new method could prove to be cost effective than the existing prostate specific antigen (PSA) test.
The findings of this study were published in the journal “Analytical Methods”. Further details on this new test discovered by Casey Burton of Lake Ozark, Mo., are related below:
An undergraduate student’s technique for detecting certain metabolites in urine samples could lead to a simpler and more accurate way to test for prostate cancer.
Developed by Casey Burton of Lake Ozark, Mo., a senior chemistry major at Missouri University of Science and Technology, the technique also could prove to be less expensive than conventional prostate-specific antigen (PSA) testing for prostate cancer.
That is because Burton’s technique does not require the use of high-tech instrumentation often used to detect metabolites. Instead, his technique relies on a simple chemical reaction as well as diagnostic equipment that is available in most health clinics. Burton also believes his approach would be more accurate than PSA tests, which “cannot accurately differentiate between benign prostate conditions and active prostate cancer,” Burton writes in a recent research article published in the journal Analytical Methods.
“This lack of sufficient diagnostic techniques for prostate cancer highlights the need for more effective screening methods,” he writes in his paper, “A novel enzymatic technique for determination of sarcosine in urine samples.” The paper was published in Analytical Methods, Vol. 4, 141, in January 2012. In the journal article, Burton explains how treating urine samples with a certain enzyme can determine the concentration of the metabolite sarcosine. Enzymes interact with a substrate, or molecule, to cause a chemical reaction that can be measured through various analytical techniques.
Until recently, the presence of sarcosine in urine was thought to be linked to prostate cancer, but that correlation has been refuted, Burton says. Even so, his method for detecting the presence of sarcosine could be used to test for the presence of other metabolites that may be linked to various diseases. The enzyme he used is one of a broad class of enzymes that operate similarly on molecules like amino acids and nucleic acids, among others. Click here to read the full extract.
This new development is a welcomed one even at this time when there is controversy as to the benefits of the PSA test.
As simpler and cheaper test, many men will face fewer challenges in terms of discomforts and financial constraints when going to diagnose cancer of the prostate. The use of common tools and simple chemical procedures to detect prostate cancer is a cost saving effort.
It is hoped that the prostate cancer research will improve study of this new technique so as to give men better option when treating prostate cancer.
