Context-dependent prognostic role of neutrophils and mast cells in primary colorectal cancer and liver metastases

Figure 1 Distribution of CD66b+ polymorphonuclear neutrophils and CD117+ mast cells in non-tumor mucosa, primary colorectal cancer and liver metastasis. A: Cell densities between non-tumor mucosa and all regions of interest of primary colorectal cancer in synchronous group and metachronous group; B: Cell densities between all regions of interest of liver metastasis (LM) in synchronous group and metachronous group. Friedman ANOVA with Dunn’s post hoc test were used for comparisons between regions of interest. ^aP < 0.05; ^bP < 0.01; ^cP < 0.005; ^dP < 0.001. NM: Non-tumor mucosa; TC: Tumor center; IM: Inner margin; OM: Outer margin; PT: Peritumor zone.
