Significance of Macrophage Chemoattractant Protein-1 Expression and Macrophage Infiltration in Squamous Cell Carcinoma of the Esophagusa

Abstract

These results suggest that MCP-1 expression and macrophage infiltration is associated with angiogenic promotion in esophageal SCC. MCP-1 expression may be interactively associated with macrophage infiltration in esophageal SCC; MCP-1 may play an important role in tumor angiogenesis through production of angiogenic factors, such as TP, by recruited macrophages in esophageal SCC. Furthermore, CCR-2 expression in vascular endothelial cells may participate partially in angiogenesis. Clinicopathologically, esophageal SCC patients with MCP-1 expression have no favorable prognosis.
