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

Figure 2 Distribution of CD66b+ polymorphonuclear neutrophils and CD117+ mast cells between different regions of interest of primary colorectal cancer and liver metastasis in synchronous and metachronous groups. A: CD66b+ polymorphonuclear neutrophils; B: CD117+ mast cells. Friedman ANOVA with Dunn’s post hoc test were used for comparisons between regions of interest. ^aP < 0.001; ^bP < 0.01; ^cP < 0.005. pTC: Tumor center of primary colorectal cancer; mTC: Tumor center of liver metastasis; pIM: Inner margin of primary colorectal cancer; mIM: Inner margin of liver metastasis; pOM: Outer margin of primary colorectal cancer; mOM: Outer margin of liver metastasis; pPT: Peritumor zone of primary colorectal cancer; mPT: Peritumor zone of liver metastasis.
