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

Figure 3 Associations between disease-free survival and high vs low densities of CD66b+ polymorphonuclear neutrophils and CD117+ mast cells in regions of interest of primary colorectal cancer and liver metastasis. A: Polymorphonuclear neutrophils (PMNs) in outer margin (OM) of synchronous liver metastasis (LM); B: PMNs in peritumor zone of synchronous LM; C: PMNs in OM of primary colorectal cancer (pCRC) in the metachronous group; D: PMNs in tumor center (TC) of LM in the metachronous group; E: Mast cells in TC of pCRC in the metachronous group. Orange and blue dotted lines: 95%CIs of Kaplan-Meier curves in “low” and “high” groups.
