N-acetylglucosaminidase (NAG) has been employed to detect macrophage accumulation/activation. Myeloperoxidase (MPO) is considered a marker for neutrophils activity/accumulation. Vascular Endothelial Growth Factor (VEGF) is as strong pro-angiogenic cytokine. The aim of this study was to measure the systemic inflammatory response by measuring serum levels of NAG, MPO and VEGF in women diagnosed with breast cancer and associate this response to the peritumoral inflammatory infiltrate and to prognostic factors. Serum samples obtained from women with no evidence of disease (n = 31) and with breast cancer (n = 68) were analyzed for the activities of NAG, MPO and VEGF by enzymatic assay. Serum levels of NAG and VEGF were higher in healthy volunteers (P < 0.0001) and serum levels of MPO were higher in patients with breast cancer (P = 0.002). Serum levels of NAG were positively correlated to serum levels of MPO and VEGF (P < 0.0001 and P = 0.0012, respectively) and MPO and VEGF serum levels had also a positive correlation (P = 0.0018). The inflammatory infiltrate was not associated to serum levels of the inflammatory markers, and higher levels of MPO were associated to lymphovascular invasion negativity (P = 0.0175).
