CRC Research Update

SCREENING
Updated ACS Guideline Addresses Blood Tests for Colorectal Cancer Screening
A JAMA article by Rubin discusses what an updated ACS guideline says about blood-based screening tests for colorectal cancer. (JAMA)
LIVING WITH CRC
Resourcefulness May Buffer Stress and Improve Quality of Life for Ostomy Patients
A cross-sectional study of 464 colorectal cancer patients with intestinal ostomy found that resourcefulness mediated the relationship between perceived stress and quality of life, suggesting a potential target for supportive interventions. (Front Psychiatry)
RESEARCH
New Computational Model Predicts Drug Combinations That Account for Microbiome Effects
Researchers developed a microbiome-aware framework combining machine learning and metabolic models to predict synergistic drug combinations for colorectal cancer in the presence of Fusobacterium nucleatum and other microbes. (Cell Rep Methods)
LIVING WITH CRC
Prediagnostic Weight Loss May Explain the "Obesity Paradox" in CRC Survival
A multicenter study of colorectal cancer patients found that cancer-associated weight loss before diagnosis may account for the apparent survival advantage seen in patients with elevated BMI at diagnosis. (JAMA Netw Open)

🔬 Under 50 Spotlight

Research relevant to early-onset and younger CRC patients

Referral Center Reports Characteristics of Early-Onset CRC Patients
A retrospective cohort study of 56 patients under age 50 with colorectal cancer (median age 42 years) found the most frequent tumor location was the right colon. (Acta Gastroenterol Latinoam)
Rare GALT/Dome Carcinoma Found in Woman With Lynch Syndrome
A woman in her early 40s with MLH1-deficient Lynch syndrome was incidentally found to have a cecal GALT/dome carcinoma during routine surveillance, raising management questions about prophylactic colectomy versus endoscopic surveillance. (ACG Case Rep J)

🧬 Biomarker Spotlight

Research by genetic subtype — Lynch syndrome, MSI-H, and more

MLH1-Deficient Lynch Syndrome Case Highlights Management Dilemma
The co-occurrence of a germline MLH1 pathogenic variant and a GALT/dome carcinoma raises questions about optimal management in the absence of high-risk histologic features. (ACG Case Rep J)

Stay informed, stay hopeful — research continues to advance our understanding of colorectal cancer.
