IL10 and digestive system cancer: Macrophage density at the invasive front of a tumor is associated with lower potential of hepatic metastasis & worse overall survival in colon cancerMacrophages within tumors predominantly expressed HLA‐DR (M1‐like subtype, proinflammatory) & IL‐10 (M2‐like subtype, anti‐inflammatory). Fewer cells were TGF‐β1 positive (M2‐like subtype, anti‐inflammatory). Clear conclusions on an M1‐like or M2‐like overall subtype by analyzing cell surface markers could not be drawn
