RESUMO
A study of interleukin-6 (IL-6), hepcidin-25 (GP-25) was conducted in 22 patients with breast cancer before neoadjuvant chemotherapy and in 27 healthy women in the control group. Significant expression of the GP-25 protein was revealed in breast cancer patients, compared to control. The rates were high both in patients with anemic sindrome (AS) and without it (p <0.01). Latent iron deficiency, AS, IDA and functional iron deficiency (FJ) were more often detected in patients with stage III disease. A significant difference in the parameters of GP-25 and IL-6 was noted, the indicators were higher in patients with stage III (p <0.01). No close correlation was found between IL-6, GP-25 and other acute-phase proteins (FR, CRP) at the initial stages of AS formation. On the contrary, a positive correlation was observed in patients with IDA and FJ between IL-6 and all acute-phase proteins (GP-25, FR, CRP). However, a small number of observations do not allow an unambiguous conclusion about the role of IL-6 and GP-25 expression in the development of AS in cancer patients with breast cancer and requires further study.
