Expression profile of interleukin-6, 4-hydroxy-2-nonenal, and hypoxia-inducible factor 1-α in women with breast cancer and their association with clinicopathological parameters.

The data obtained show that the presence of lipid peroxidation (4-HNE) is a marker of oxidative stress, and that IL-6 is a good prognostic factor due to its negative effect on the number of lymph nodes. Furthermore, age and BC molecular subtypes do not influence the serum concentrations of IL-6,4-HNE, and HIF-1α.
