Introduction: Pancreatic cancer is a highly lethal malignancy. Chemokines may control the macrophage infiltrate found in many solid tumors. Monocyte chemoattractant protein-1 (MCP-1/CCL2) plays a key role in the recruitment and activation of monocytes during inflammation. MCP-1 is a small chemotactic protein that has been found in several kinds of tumor tissue samples and functions as a key regulator of cancer progression. This study was conducted to investigate the serum levels of MCP-1 in patients with pancreatic adenocarcinoma (PA) and the relationship with tumor progression and known prognostic parameters.
