To investigate interactions between tumor cells and macrophages in angiogenesis, we examined macrophage infiltration, tumor vascularity and expression of monocyte chemoattractant protein (MCP)-1, CC chemokine receptor 2 (CCR2) and vascular endothelial growth factor (VEGF) in 57 archival specimens from patients with esophageal dysplasia (n = 9) and squamous cell carcinomas (n = 48).
