Relationships between LMR and other parameters. (A): LMR exhibited a statistically significant inverse correlation with NLR (r = −0.685, p < 0.001). (B): LMR showed a statistically significant inverse correlation with MDSCs (r = −0.531, p = 0.003). (C): LMR exhibited a statistically significant inverse correlation with MDSCs in patients with stage II + III disease (r = −0.424, p = 0.044). LMR: lymphocyte-to-monocyte ratio, NLR: neutrophil-to-lymphocyte-ratio, MDSCs: myeloid-derived suppressor cells.
