Abstract
Surgical removal of the tumor is currently the first-line treatment for lung cancer, but the procedure may accelerate cancer progression through immunosuppression. However, whether CCL2 (C-C motif chemokine ligand 2) enhances cancer progression by affecting regulatory T cells (Tregs) remains unknown. We found that the volume and weight of tumors were larger in the surgical trauma group than in the control group. CCL2 expression and Treg abundance were increased in tumor tissues after surgical trauma, and CCL2 expression was positively associated with Treg abundance. These results demonstrated that surgical trauma contributes to lung cancer progression by increasing CCL2 expression, thus promoting Treg recruitment.Keywords
