The plasmatic levels of VEGF (breast cancer: range 31.2 – 177.9 pg ml−1; controls: 43.7 – 59.6), IL-10 (breast cancer: 20.9 – 31.1; controls: 16.9 – 21.7) and spermine (breast cancer: 0.25 – 4.05; controls: 0.66 – 2.51) did not significantly differ between groups. Here, IL10 is linked to breast carcinoma.
