The aim of the study was to assess the value of vascular endothelial growth factor (VEGF) measurements in breast cancer patients with respect to recognized clinicopathological prognostic factors. The study was conducted in 87 women with histologically confirmed breast cancer who underwent surgical treatment and 37 healthy women. Vascular endothelial growth factor concentration levels in the blood samples of patients were correlated with the size of the primary tumor, lymph nodes in the armpit, cancer stage, histological type, grading, multifocality, status of estrogen and progesterone receptors and HER-2 protein expression. Statistical analysis did not show any correlation between concentrations of VEGF and any of the selected parameters. The comparison of VEGF concentrations showed a slightly raised level of VEGF in women with the disease as opposed to the healthy subjects but the differences were not statistically significant (p = 0.472). Similar results were obtained for marker CEA (p = 0.09), while the level of Ca 15-3 in both groups differed significantly (p < 0.001) reaching higher values in the patients with diagnosed breast cancer. Vascular endothelial growth factor concentrations in breast cancer patients do not correlate with recognized clinicopathological prognostic factors and CEA and Ca 15-3 markers, which does not preclude the potential role of VEGF as an independent prognostic factor.
