Long non-coding RNAs in colorectal cancer: shaping the tumour microenvironment and advancing precision oncology.

Basic sciencebasic sciencetranslationalbiomarkercolorectal cancer
Clinical takeawayNo clinical action yet: a mechanistic review of lncRNAs in CRC TME, proposing potential biomarkers and therapeutic strategies without human data.
What it foundLong non-coding RNAs (lncRNAs) regulate colorectal cancer (CRC) tumor microenvironment (TME) via immune modulation, vascular remodeling, and extracellular matrix dynamics, with dual roles as oncogenes or tumor suppressors.
ContextExpands understanding of CRC biology by detailing lncRNA roles in TME, but remains preclinical with no direct clinical validation.

Decision at stakethe potential for lncRNAs to inform future colorectal cancer screening or therapeutic strategies

Begin average-risk colorectal cancer screening at age 45 using a patient-centered shared-decision modality choice, colonoscopy every 10 years (preferred) or annual FIT as Tier 1 options, with multi-target stool DNA every 3 years, CT colonography every 5 years, or flexible sigmoidoscopy every 5 to 10 years as Tier 2 alternatives. A positive stool-based test requires diagnostic colonoscopy, and stool tests should not be ordered for patients who would decline follow-up colonoscopy. Generally stop at age 75 with individualized decisions for ages 76-85 and no screening beyond 85.
