A new method for detecting bowel cancer is more than 90% accurate at predicting which higher risk people will develop the disease, research found. People with inflammatory bowel disease (IBD), such as Crohn's and ulcerative colitis, are known to have an increased chance of bowel cancer, but not all will develop it.
Now, a study funded by Cancer Research UK has shown more than 90% accuracy in predicting bowel cancer risk in the next five years in a high-risk group of people with IBD. This could lead to a blood test which will inform doctors which IBD patients are most at risk of bowel cancer.
IBD can irritate the lining of the bowel and can cause abnormal pre-cancerous cells to form if left untreated. To identify people's cancer risk, scientists at the Institute of Cancer Research (ICR), working with doctors at St Mark's in London, the UK's specialist bowel hospital, found that people with IBD whose pre-cancerous cells had lost multiple copies of their DNA were far more likely to go on to develop bowel cancer.
The scientists also created an algorithm that calculates the risk of future bowel cancer, based on the exact pattern of the DNA which is altered in the pre-cancerous cells. Doctors look for clues on why 'super survivors' overcome cancer in first global study.
