    Colorectal cancer liver metastases (CRLM) contribute to systemic immunosuppression and poor prognosis, necessitating further study of immune landscape changes post-resection.

  • 2

    Surgical resection of CRLM leads to significant remodeling of T cell composition, particularly an increase in CD4+ T cells among circulating CD3+ T cells.

  • 3

    Postoperative analysis showed a decrease in TIM3+ CD4+ T cells, while PD-1+ CD4+ T cells exhibited modest downward trends, indicating changes in immune exhaustion markers.

  • 4

    Patients with recurrence had a higher proportion of S100A9+ monocytic myeloid-derived suppressor cells (M-MDSCs) post-surgery, suggesting a link to poor outcomes.

    KRAS-mutated tumors may be associated with distinct postoperative immune profiles, highlighting the need for further investigation into immune responses after liver resection.
