Detecting pancreatic cancer through stool samples - what we know 4 hrs ago9 Mar 2022 10:42
Scientists may be able to detect pancreatic cancer by looking at microorganisms in stool samples, according to new research.
The study, part-funded by Worldwide Cancer Research, has raised hopes of the first screening test for pancreatic cancer.
Researchers found that 27 microbial species in stool samples could pinpoint people at high risk of the most common form of pancreatic cancer.
The 27 microbes, which were mostly bacteria, could distinguish well between people without cancer and those with the disease, both in advanced and early stages.

Microbiome - the collection of fungi, bacteria and viruses that live inside our bodies - is known to interact with the immune system.
Pancreatic cancer is deadly and can be very difficult to treat, with only around one in four people surviving one year or more after diagnosis.
Pancreatic cancer is the fifth most prevalent cancer in the UK, one doctor said, with about 10,000 new cases recorded every year.
The study, published in the journal Gut, involved 136 people, including 57 with pancreatic cancer (25 early stage and 32 advanced), 50 without cancer acting as controls, and 29 patients with chronic pancreatitis, where the pancreas has become permanently damaged by inflammation.
Rapid pancreatis cancer test kits
Experts from the Spanish National Cancer Research Centre (CNIO) and the European Molecular Biology Laboratory (EMBL) concluded it is “feasible” for a screening programme to be developed using stool samples that may help pick up pancreatic cancer.
A patent has been applied for development of a pancreatic cancer diagnostic kit that detects the microorganisms in stool samples in a rapid way.
Dr Helen Rippon, chief executive of Worldwide Cancer Research, said: “This new breakthrough builds on the growing evidence that the microbiome – the collection of microorganisms that live side by side with the cells inside our body – is linked to the development of cancer.
“What’s amazing about this discovery is that the microbiome of stool samples from patients could be used to help diagnose pancreatic cancer early.
“Early detection and diagnosis are just as important an approach to starting new cancer cures as developing treatments.
“This research provides hope that an effective, non-invasive way to diagnose pancreatic cancer early is on the horizon.”
