CRC Research Update

Metabolic pathway drives cetuximab resistance in metastatic colorectal cancer
Researchers found that cetuximab treatment stabilizes the enzyme GDH1, leading to accumulation of α-ketoglutarate that remodels the tumor immune microenvironment and drives resistance; depleting GDH1 sensitized cancer cells to cetuximab in preclinical models. (Cell Death Dis)
Computer-aided detection improves colonoscopy adenoma detection across expertise levels
A retrospective study of 724 matched patients found that computer-aided detection (CADe) systems improved adenoma and polyp detection rates during colonoscopy for both expert endoscopists and trainees under diverse clinical conditions. (In Vivo)
H. pylori infection linked to increased colorectal cancer risk in two large trials
Analysis of two randomized trials in China involving over 180,000 participants found that H. pylori infection was associated with increased colorectal cancer risk, with the association modified by genetic predisposition. (Gut)
Multi-omics deep learning model predicts anti-EGFR therapy response in liver metastases
A multi-center study developed a deep learning framework integrating multi-omics data to predict which RAS wild-type colorectal cancer liver metastases patients will benefit from cetuximab therapy, addressing primary resistance challenges. (Curr Cancer Drug Targets)

🔬 Under 50 Spotlight

Research relevant to early-onset and younger CRC patients

Rare neurological syndrome as first sign of colon cancer in 43-year-old
A 43-year-old man with progressive sensory neuropathy was diagnosed with Stage IIIA colon adenocarcinoma after anti-Hu antibodies led to discovery of an ascending colon mass; the patient had not undergone recommended early screening despite significant family history. (ACG Case Rep J)

🔎 Screening Watch

Screening guidelines, early detection, and prevention advances

French multicenter study to evaluate ctDNA after liver metastasis surgery
The CLIMES PRODIGE 77 study will enroll 232 patients undergoing curative-intent liver metastasis resection to evaluate circulating tumor DNA as a biomarker for detecting minimal residual disease and predicting prognosis. (BMJ Open)
Cross-kingdom gut microbiome model predicts colorectal adenomas
Researchers analyzed 296 fecal samples using metagenomic sequencing and developed a predictive model incorporating bacteria, viruses, archaea, and fungi to identify colorectal adenomas, the main precancerous lesion. (Front Microbiol)

💙 Living with CRC

Survivorship, quality of life, and supportive care

Prehabilitation study evaluates exercise and nutrition before GI cancer surgery
A prospective controlled trial evaluates the feasibility, safety, and preliminary effectiveness of supervised moderate-to-high intensity exercise combined with nutritional counseling in gastrointestinal cancer patients scheduled for surgery. (BMC Cancer)

Research continues to advance our understanding of treatment resistance, early detection, and supportive care strategies for the colorectal cancer community.
