Why is colorectal cancer aggressive in younger patients? Boston researchers discover new clues
WCVB • • general
Key Points:
- Boston-based researchers identified biological factors that may explain why colorectal cancer is more aggressive in patients under 50, analyzing 189 tumors with detailed gene activity measurements.
- Younger patients' tumors showed a higher proportion of connective and supporting cells, which are associated with chemotherapy resistance in various solid cancers.
- The study found stronger cell signaling in tumors from younger patients, potentially aiding cancer spread to nearby tissues, along with distinct RNA activity involving long non-coding RNAs whose functions are not fully understood.
- Published in "Nature Medicine," the research offers key insights but does not yet establish a direct link between these biological differences and the aggressiveness of early-onset colorectal cancer.
- Lead researcher Dr. Ramnik J. Xavier emphasized that the findings pave the way for future studies on how these cellular programs interact with diet and gut microbes to contribute to early-onset colorectal cancer.
