Diabetes and Colorectal Cancer Risk and Survival According to Tumor Immunity Status

T2D disproportionately affects CRC risk and survival in tumors with low immune infiltration, suggesting a continuum of T2D's impact from tumorigenesis to prognosis, through systemic and tumor-specific immune modulation. These findings highlight the need for precision prevention strategies integrating metabolic and immune-based interventions to mitigate CRC burden in patients with T2D.
