Concentration of interleukin-6 (IL-6), interleukin-8 (IL-8) and interleukin-10 (IL-10) in blood serum of breast cancer patients.
OBJECTIVE
Interleukins may stimulate cancer cells growth and contribute to locoregional relapse as well as metastasis. Permanent synthesis and release of these cytokines leads to augmentation of their serum concentration that might be utilized as a marker of immunity status and immune system activation in prognosis and monitoring of the course of cancer.


METHODS
Therefore, in the present study we assessed the concentration of IL-6, IL-8 and IL-10 in blood serum of breast cancer patients to determine whether it correlates with the disease progression.


RESULTS
We showed statistically higher serum concentrations of IL-6, IL-8 and IL-10 in breast cancer patients in comparison with healthy women, which also correlated with clinical stage of breast cancer.


CONCLUSIONS
The present study indicates that elevated IL-6, IL-8, and IL-10 serum concentration, are strongly associated with breast cancer and correlate with clinical stage of disease. It was feasible that it can be used to diagnose women with breast cancer and to identify patients with a poor prognosis who may benefit from more aggressive management.
