Increase in Colorectal Cancer Among Youth: Possible Explanations Proposed by Researchers
Gut bacteria may trigger early-onset colorectal cancer
It appears our friendly gut bacteria might not always be so benign. A groundbreaking study published this week in Nature alleges that some strains of Escherichia coli produce a mutagenic toxin called colibactin, which can spark early onset colorectal cancer (EOCRC) in young adults.
Lead by scientists at the University of California, San Diego, this research sheds light on the somewhat perplexing increase in EOCRC cases in recent years. The team's discovery could help explain this puzzling trend, though more investigation is needed to establish a direct causative link.
Colorectal cancer is the fourth most common cancer, afflicting approximately 150,000 Americans annually, and accounting for around 50,000 deaths per year. Once on a downward trend in incidence, this cancer is currently more prevalent in younger and middle-aged adults, a troubling development. The American Cancer Society reports a 2.4% yearly increase in colorectal cancer among individuals under 50 since 2012.
To unveil the global variations in colorectal cancer, the research team analyzed genetic signatures from nearly 1,000 colorectal cancer patient samples from around the world. Surprisingly, they found that colibactin-related mutations were about three times more common in early-onset cancers compared to late-onset counterparts. These mutations also seemed to appear at the early stages of tumor growth, emphasizing their relevance in fueling these cancers.
So, are these deadly bacteria the missing link behind EOCRC? The team argues that the more frequent colibactin exposure during early life could be the primary cause of these tumors. They further postulate that probiotics might eliminate the harmful strains of E. coli implicated in EOCRC.
However, the research doesn't put all the blame on colibactin. It seems the gut microbiome could be influenced by factors like diet and antibiotic use, cultivating ideal conditions for colibactin-producing E. coli in places like the U.S. Further research should explore the interplay between diet, colibactin, and colorectal cancer risk.
This research could lead to early detection tests, interventions, and even preventive measures aimed at reducing the escalating rate of EOCRC. Yet, future advancements hinge on continued funding. The potential budget cuts from the National Institutes of Health under President Donald Trump could hamper crucial cancer research, impacting not just the U.S., but global cancer research as well.
