CRC Research Update

  • TRIAL DATA

    Early-onset colorectal cancer in Korea shows lower mortality than late-onset disease

    A nationwide study of 20,941 patients found that early-onset CRC (diagnosed before age 50) was associated with lower overall mortality, cancer-specific mortality, and non-cancer mortality compared to late-onset disease, with the mortality difference greatest in localized disease and stronger in MSI tumors.

  • SCREENING

    Combining FIT with risk factors improves colonoscopy efficiency

    A systematic review of 19 studies found that adding risk factors such as age, sex, smoking, and fecal hemoglobin levels to fecal immunochemical testing modestly improved the yield and efficiency of colonoscopy for advanced colorectal neoplasia, though a small proportion of cases were missed.

  • RESEARCH

    Circulating tumor DNA detects recurrence months before imaging

    A review of 94 publications found that postoperative ctDNA positivity was consistently associated with increased recurrence risk and poorer survival, with serial monitoring identifying molecular recurrence approximately 2.5 to 11.5 months before conventional surveillance. (Current Oncology)

Screening guidelines, early detection, and prevention advances

  • Rural residents more likely to pay full cost of colonoscopy

    A national survey found 4.12% of rural residents reported paying all colonoscopy costs versus 3.01% of urban residents, with uninsured status and Hispanic ethnicity also associated with higher out-of-pocket spending. (Journal of Rural Health)

This week's research spans survival outcomes in early-onset disease, advances in minimal residual disease detection, and ongoing efforts to improve screening access and efficiency.
