CRC Research Update

SCREENING
Abbott launches SimpleScreen CRC blood test for average-risk adults 45+
The FDA-approved blood-based screening test, developed by Freenome and sold exclusively by Abbott, is designed for adults unwilling or unable to undergo colonoscopy. (Fierce Biotech)
RESEARCH
Early-onset CRC shows distinct genomic landscape in dual-cohort analysis
Analysis of TCGA PanCancer Atlas and MSK-IMPACT 50K cohorts reveals reproducible mutational differences in colorectal cancer diagnosed before age 50, with implications for biomarker-driven treatment. (PLoS One)
LIVING WITH CRC
Network meta-analysis compares microbiota-modifying interventions for chemotherapy-related GI disorders
Systematic review of randomized trials aimed to compare the effects of microbiota-modifying interventions, primarily probiotics and synbiotics, on gastrointestinal symptoms during chemotherapy in adults with CRC. (Semin Oncol Nurs)
RESEARCH
MSI-H/dMMR prevalence varies by age and sex in Japanese cancer cohort
Study of 1,130 older patients (median age 78) with gastric, colorectal, and endometrial cancers characterized deficient mismatch repair protein expression patterns, informing immunotherapy eligibility in aging populations. (Jpn J Clin Oncol)

🔬 Under 50 Spotlight

Research relevant to early-onset and younger CRC patients

Qualitative review maps illness experiences and supportive care needs in early-onset CRC
Systematic review synthesizes challenges faced by patients diagnosed before age 50 during critical periods of relationship formation, family building, and career development. (J Clin Nurs)

🔎 Screening Watch

Screening guidelines, early detection, and prevention advances

UK COLO-COHORT study enrolls nearly 5,000 participants for CRC prevention research
Prospective multicentre study across 27 UK sites collected demographics, lifestyle factors, biospecimens, and colonoscopy outcomes from adults undergoing screening and routine referral. (BMJ Open Gastroenterol)

This week's research spans blood-based screening advances, genomic characterization of early-onset disease, and supportive care strategies for chemotherapy-related side effects.
