New Prostate Cancer Test Shows Promise

Tuesday, 14 Aug 2012 03:03 PM


A chemistry student at Missouri University of Science and Technology has developed a possible new urine test for prostate cancer.
The development, reported by MUST senior chemistry major Casey Burton in the journal Analytical Methods, detects certain “metabolites” in urine samples – a technique that could mark a significant improvement over conventional prostate-specific antigen (PSA) testing.
Burton noted PSA testing requires using high-tech instrumentation to detect metabolites, but his technique relies on a simpler, less costly analysis of chemical reactions by diagnostic equipment that is already available in most health clinics.

Burton also said his technique is more accurate than PSA tests that don’t distinguish between benign prostate problems and cancer.

"This lack of sufficient diagnostic techniques for prostate cancer highlights the need for more effective screening methods," he said in the journal report.

Specifically, Burton found concentrations of the metabolite sarcosine in urine can be determined by treating urine samples with a certain enzyme that causes a chemical reaction that is measurable.

Until recently, the presence of sarcosine in urine was thought to be linked to prostate cancer, but that correlation has been refuted, Burton said. Still, 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.

"Instead of using fancy machinery, I can use an enzyme to make the chemical [reaction]," he said. "So we can effectively analyze our urine samples, and determine whether or not they contain metabolites."

The system's low cost is also a plus.

"This costs a tenth of a penny per sample, compared with the $70 or so it costs to get a PSA test at a health clinic or doctor's office," he said.
