Cytokines in breast cancer patients during radiation therapy: complementary effects of biologically active food additive containing salmon soft roe and vitamin C
We studied some effects of a biologically active food additive (BAFA) «DNAaC» which contains DNA from salmon soft roe and vitamin C as active substances. This BAFA was investigated as a complementary remedy during radiation therapy of women with breast cancer (BrC), with respect to dynamics and levels blood serum cytokines, i.e., early hematopoietic factors (IL-3, GM-CSF, TNFa), and balance of marker cytokines for Th1- and Th2-response (IFNγ, IL-10). It was shown that «DNAaC» has modulating effect on secretion of all investigated cytokines. There was, however, a higher and statistically valid corrective effect upon GM-CSF, along with increase of initially low IFNγ and TNFa concentrations, and reduction of initially high IL-10 levels. Hence, «DNAaC» contributes to improvement of cell-mediated immune deficiency, stabilization of hematopoietic system, and brings about tolerance to basic treatment approaches in oncological diseases
