- Pancreatic cancer represented
3.2% , and prostate cancer represented 14.2% of all brand-new cancer cases in 2022 in the United States. - Pancreatic cancer, in specific, can be hard to deal with and has a much greater death rate than numerous types of cancer, what might be because of the truth it is frequently identified late.
- Korean scientists just recently created a method to spot both pancreatic and prostate cancer with a urine test.
- With pancreatic cancer growing in younger females, this innovation might offer a path to earlier cancer detection and treatment.
A group led by scientists from the Surface & Nano Materials Division of the Korea Institute of Materials Science just recently released a research study in Biosensors and Bioelectronics revealing a brand-new method to spot pancreatic and prostate cancer utilizing a urine test.
They state the test can have up to a 99% detection rate.
Pancreatic and prostate cancer impact countless individuals in the U.S.. The American Cancer Society approximates that roughly 64,000 individuals will get a
Some symptoms and signs of pancreatic cancer consist of:
- jaundice
- indigestion
- queasiness and throwing up
- pale gray or fatty stool
Unfortunately, pancreatic cancer is typically just spotted in later phases, and the death rates with this form of cancer are high. The 5-year survival rate for pancreatic cancer is 12%.
Additionally, pancreatic cancer rates are increasing in the U.S. each year and are increasing at faster rates in younger females, especially in Black females. A current research study revealed that pancreatic cancer rates in Black females under age 55 increased 2.23% compared to Black guys of the exact same age group.
The 5-year survival rate for prostate cancer is 97%. With the exception of skin cancer, prostate cancer is the most typical cancer in guys, and 1 in 8 guys get a medical diagnosis throughout their life time.
Not all guys experience signs of prostate cancer, however physicians can spot it through regular screening. However, for guys who do experience signs, a few of those might consist of regular urination and agonizing urination.
Current screening and screening for either pancreatic or prostate cancer can be rather intrusive and in some cases costly.
Some methods physicians test for pancreatic cancer consist of using CT and MRI scans, and for prostate cancer screening, physicians utilize blood screening, transrectal ultrasounds, or rectal examinations.
Since biofluids can be important in spotting or identifying particular conditions, the scientists in this research study wished to make use of these in an advanced method—by utilizing urine to spot cancer metabolites.
“Urine is a promising biofluid for disease diagnosis because most metabolic components are excreted via the urinary tract,” compose the authors.
The scientists note that previous research studies reveal that the metabolite substances present in urine are various in urine of individuals without cancer versus the urine of individuals with cancer, however that formerly, the only method to spot those substances was through a “laborious” procedure.
By establishing a boosted Surface-improved Raman scattering (SERS) sensing unit, the researchers had the ability to spot “hot spots” in urine samples. These locations got and magnified particular molecular substances that point towards cancer.
After producing a urine test strip and a portable screening device, the scientists obtained urine samples from a variety of clients with pancreatic or prostate cancer to see how well the test worked.
In addition to acquiring urine samples from 19 clients with pancreatic cancer and 39 clients with prostate cancer, the scientists gathered samples from 40 cancer-free males and 20 cancer-free women.
The test was total able to spot 99% of the malignant samples.
“Since early diagnosis is the most important for incurable diseases such as cancer, we expect this technology to provide a new diagnostic method,” says research study author and research study lead Ho Sang Jung, who supervises of the research study.
Dr. Domenech Asbun, a hepatobiliary, pancreas, and foregut cosmetic surgeon at Miami Cancer Institute, part of Baptist Health South Florida, talked with Medical News Today about the research study.
“The authors use an interesting combination of technology—including established complex physics and cutting-edge deep learning models—in attempts to solve a long-standing problem: how do we diagnose occult cancers in the general population before it’s too late?” he said.
“The findings in this study may provide an important step forward in finding practical ways to diagnose cancers that oftentimes grow undetected. If the results can be reproduced on a larger scale, these tests may allow for early treatment of cancers that are quite often deadly when undetected for too long.”

Jung talked with Medical News Today about the future of this research study and said they are broadening on it by checking more topics.
“The number of patients tested using our system is continuously growing. Our team is trying to get as many clinical samples as possible to build more general deep-learning models with better accuracy,” said Jung.
Jung likewise said they wish to have the ability to test for more than simply 2 kinds of cancer.
“The next step in this research is broadening applicable cancer types. Now, our team just finished testing clinical samples of pancreatic cancer, prostate cancer, lung cancer, and colorectal cancer simultaneously, and our team is expected to submit an article this year.”
In addition to broadening on cancer types, Jung says they imagine at-home screening packages in the future.
At home tests might be within reach
“Because the developed diagnostic method uses urine, it is noninvasive thus it would be more beneficial in terms of usability when it is applied for self-testing or rapid-kit-testing at home, pharmacy, or any places where they can provide some clinical information.”
