Surgery-induced decline in circulating dendritic cells in operable cancer patients: a possible explanation of postoperative immunosuppression.

Abstract

In addition to the well-demonstrated surgery-induced lymphocytopenia, this preliminary study shows that the surgical treatment may determine a significant decrease in circulating immature and mature dendritic cells. Because of the fundamental role of dendritic cells in regulating the immune responses, surgery-induced decline in circulating dendritic cells number could play a role in determining the immunosuppressive status, which characterizes the postoperative period.
