Could a urine test detect pancreatic and prostate cancer? Study shows 99% success rate

A easy urine take a look at might detect pancreatic and prostate most cancers with as much as a 99% fee of accuracy, says a workforce of researchers from the Floor & Nano Supplies Division of the Korea Institute of Supplies Science.

Dr. Ho Sang Jung, lead writer of the research, mentioned most cancers urine incorporates most cancers metabolites and is completely different from regular urine. 

The research, lately printed within the journal Biosensors and Bioelectronics, aimed to find out whether or not urine exams might detect these most cancers metabolites, that are launched by most cancers cells to advertise tumor development.

After the urine pattern was positioned on a take a look at strip, the researchers used a particular sort of sunshine scattering approach that generated a “fingerprint spectrum of chemical compounds,” which detected the most cancers metabolites.

Dr. Jung mentioned the exams can detect most cancers at numerous phases. 

“The aim of creating this sort of know-how is to display the most cancers affected person earlier than they go to the hospital,” he informed Fox Information Digital in an e mail. 

“We’re not positive that the take a look at strip can differentiate most cancers at very early phases, however at the very least it might probably recommend the opportunity of most cancers standing — so the affected person could then go to the hospital for a exact medical checkup.”

Dr. James Anaissie, a urologist with Memorial Hermann in Houston, Texas, who was not concerned within the research, is optimistic about the way forward for this know-how — however he’s not leaping fully on board simply but.

“The aim of creating this sort of know-how is to display most cancers sufferers earlier than they go to the hospital.”

“If the take a look at is as dependable as they are saying it’s, it could have an vital function in screening, as the present PSA [prostate-specific antigen] blood take a look at we use is notoriously unreliable,” he informed Fox Information Digital in an e mail. 

“There’s a large want for one thing like this.”

Additionally, from a scientific perspective, urine testing is far simpler than blood testing, the physician mentioned.

Nevertheless, Anaissie stays a bit skeptical. 

“Though they report wonderful sensitivity and specificity for prostate most cancers, the info to help that is solely accessible upon request of the analysis workforce, they usually have virtually no tables demonstrating these findings, which I might take into account commonplace for research of this nature,” he mentioned.

“For instance, have been the sufferers identified with prostate most cancers in extreme phases, the place it’s apparent they’ve prostate most cancers even with none urine exams?” mentioned Dr. Anaissie. 

“Was it simply as correct for low-grade and high-grade cancers? At any time when I hear about thrilling new know-how, I’m at all times receptive, however with a raised eyebrow.”

Are at-home exams on the horizon?

Urine screenings can be utilized by anybody, mentioned Dr. Jung. The top purpose is for the sort of know-how to be accessible for at-home testing.

“If it might probably survive scrutiny, then it has the potential to revolutionize prostate most cancers screening.”

He foresees a number of potential sensible makes use of, together with screening for most cancers earlier than going to the hospital, monitoring for most cancers recurrence after remedy, or supplementary testing along with blood work.

Research has limitations, medical doctors admit

The research authors acknowledge some limitations of the analysis.

“It was onerous to get sufficient urine samples from most cancers sufferers,” mentioned Dr. Jung. 

His workforce used 100 samples within the research and is constantly gathering extra from hospitals all through Korea.

Additionally, as a result of it is a new know-how, it nonetheless has not been accepted by the Ministry of Meals and Drug Security in Korea for industrial use.

Anaissie additionally factors out that extra research are wanted to see if the take a look at works when there’s a urinary tract an infection or blood within the urine, which isn’t unusual in sufferers with prostate most cancers.

“Expertise like this takes a very long time to go from the lab’s proof of idea to on a regular basis use, and lots of people are going to attempt to choose it aside to verify it’s secure and dependable,” Anaissie mentioned.

“The very last thing you need is a screening take a look at that finally ends up having lots of false negatives. If it might probably survive the scrutiny, then it has the potential to revolutionize prostate most cancers screening.”

“If the take a look at is as dependable as they are saying it’s, it could have an vital function in screening, as the present PSA [prostate-specific antigen] blood take a look at we use is notoriously unreliable,” one physician mentioned. (iStock)

The researchers’ final purpose is for the urine screenings to increase ultimately to different sorts of cancers, similar to lung most cancers and colorectal most cancers.

“We’re at present creating a system that may classify 4 most cancers sorts — pancreatic most cancers, prostate most cancers, lung most cancers and colorectal most cancers — concurrently,” Jung informed Fox Information Digital. 

He expects the follow-up research to be printed someday this yr.
