Individuals who suffer from inflammatory bowel disease (IBD) are more likely to develop colorectal cancer. Every one to three years, people with IBD frequently undergo colonoscopies to screen for colorectal cancer. Previous studies have demonstrated that identifying precancerous cells in individuals with IBD can be difficult. A new test created by researchers at London’s Institute of Cancer Research claims to be able to predict bowel cancer risk in individuals with IBD with 90% accuracy. According to earlier studies, individuals with inflammatory bowel disease (IBD), which includes Crohn’s disease and ulcerative colitis, are more likely to develop colorectal cancer than those without IBD.

Due to the chronic inflammation associated with IBD, which can lead to the growth of abnormal cells called dysplasia and the development of precancerous polyps in the intestinal tract, people with IBD are more likely to develop colorectal cancer, also known as bowel cancer. Currently, a colonoscopy is performed every one to three years to screen for colorectal cancer in individuals with IBD. Nevertheless, prior research indicates that it can be challenging to identify precancerous cells in IBD patients. Researchers at London’s Institute of Cancer Research have now created a new test that they claim can more than 90% accurately predict bowel cancer risk in individuals with IBD.

The study’s senior author, Trevor Graham, PhD, a professor of genomics and evolution and director of the Centre for Evolution and Cancer at The Institute of Cancer Research in London, stated that while individuals with IBD are more likely to develop bowel cancer, there is currently no reliable method to predict that risk. Graham told Medical News Today that the only effective treatment for people who are believed to be in imminent danger of developing cancer is surgery to remove part or all of the large bowel. This procedure may save a life. However, people are undergoing needless surgery that can change their lives because we are currently unable to determine whether a patient actually needs the procedure. However, he added, those whose risk of bowel cancer is deemed low and for whom we do not perform surgery still experience anxiety due to the uncertainty surrounding their cancer risk.

Increased risk of cancer with cellular DNA changes
Researchers discovered that individuals with IBD who had precancerous cells that either gained or lost multiple copies of DNA were more likely to develop bowel cancer. The researchers then used the precise pattern of the altered DNA in the precancerous cells to create an algorithm that would predict the risk of colorectal cancer in the future. According to Graham, individuals with IBD in the UK undergo routine colonoscopies, which involve a camera being inserted up their butt to check for early indications of cancer. A biopsy is a tiny sample of tissue taken if something odd is observed. The test we run on the biopsy is a genetic test. According to him, we have developed a test to predict an individual’s risk based on the genetic signals in their biopsy after comparing the genetic signals of those who did and did not develop cancer.

Test predicts colorectal cancer risk with over 90% accuracy
Graham and his colleagues discovered that their novel test could more than 90% accurately predict which IBD study participants who developed precancerous cells would later develop colorectal cancer within five years. Graham stated, “We hope that by accurately identifying those at risk of cancer, we will be able to provide appropriate treatment.”. Surgery can be used to remove the colon and reduce the risk of cancer in people who are at a high risk of getting the disease. We can spare people who are not at high-risk needless anxiety and care. In clinical trials that we intend to conduct in the future, we must demonstrate that our predictions are accurate for patients to benefit from this, he said.

Although bowel cancer is more likely to strike people with inflammatory bowel disease, most IBD patients do not go on to get the disease. By predicting who is actually at risk, our new test enables all patients to receive the best possible care. To demonstrate that our predictions are accurate in practical situations, we will next conduct clinical trials. In the upcoming years, we hope to be able to administer the test within the NHS.

A less invasive predictive test
Regarding this study, a board-certified gastroenterologist at Providence Saint John’s Health Center in Santa Monica, California, commended it as fantastic, outstanding, and wonderful. The truth is that we frequently perform colonoscopies and biopsies on our IBD patients to check for dysplasia or cells or tissue that may develop into cancer. After that, we must have these conversations with them. Bedford clarified, “What do we do if they do have these low-grade dysplastic cells? Do we remove your colon or do we do more frequent surveillance?

It sounds like the speaker is expressing enthusiasm about a new test for predicting cancer risk in patients with inflammatory bowel disease (IBD). A test with 90% accuracy could significantly improve clinical decision-making by identifying those at risk for cancer and allowing doctors to target therapy more effectively. This could reduce the need for invasive procedures, which is always a win for patient comfort and safety. Additionally, if the test could be adapted into a blood or stool test, it would make it even more convenient for patients, potentially improving adherence to monitoring and early intervention.
It’s exciting when advancements like this can make a real difference in patient care! Would you like more information on current developments in diagnostic tests for IBD or related cancer risks?

Determining who is at higher risk
It seems like Dr. Nilesh Vora is also highlighting the potential of this study, emphasizing how valuable it would be for gastroenterologists to have a more accurate way of identifying which patients with inflammatory bowel disease (IBD) are at higher risk for colon cancer. This would help doctors make more informed decisions on how to manage these patients and which individuals might benefit from closer monitoring or more aggressive treatments.

Dr. Vora’s perspective points to the benefit of targeted care by identifying at-risk patients, healthcare providers can potentially avoid unnecessary procedures for those not at risk, while ensuring higher-risk patients are managed more carefully. This kind of approach could streamline care and improve outcomes for patients with IBD, who already face challenges related to their condition.

It’s fascinating to see how medical fields are working together to improve outcomes for patients, and studies like this really highlight how advances in one area of medicine (in this case, diagnostic tools for cancer risk) can have a ripple effect on multiple specialties, improving patient care overall. Does this kind of collaboration between specialists and new diagnostic tests interest you?

That’s a crucial next step! Getting FDA approval for this test would be a significant milestone. If it’s approved, it could become a standard tool in clinical practice, helping doctors more accurately determine which IBD patients need frequent colonoscopies and which could safely extend the interval between screenings. Reducing the number of unnecessary colonoscopies would not only ease the burden on patients but also reduce healthcare costs and free up resources for those who truly need more frequent monitoring.

The potential for a more personalized approach to care where screenings are tailored to an individual’s actual risk—could be a game changer in managing IBD patients. The idea of offering more tailored and less invasive options for ongoing care could improve patient experience, both physically and psychologically.

If the test proves to be both accurate and accessible, it could help revolutionize the way doctors approach cancer prevention and monitoring for IBD patients. What do you think are some of the biggest hurdles in getting something like this approved by the FDA?
