    Colorectal cancer (CRC) is a leading cause of cancer-related mortality, with metastasis significantly contributing to this outcome.

  • 2

    The liver and lungs exhibit distinct immune environments that influence the efficacy of immune checkpoint inhibitors (ICIs) in metastatic CRC.

  • 3

    Liver metastases are associated with a tolerogenic niche leading to resistance to ICIs, while lung metastases show improved responses due to a more inflammatory environment.

  • 4

    Tumor-derived factors play a crucial role in shaping the pre-metastatic niche and tumor microenvironment, affecting metastatic progression and treatment response.

  • 5

    Understanding organ-specific immune landscapes is essential for developing tailored therapeutic strategies to enhance ICI efficacy in metastatic CRC.
