IL6 and breast cancer: In addition, all of the biochemical parameters we analysed were statistically significant in both breast cancer patients (NF-κB: p<0.001; sTRAIL: p<0.01; TNF-α: p<0.001; IL-6: p<0.001; PCT: p<0.001; PTX-3: p<0.001; CRP: p<0.001) and colon cancer patients (for all p<0.001) compared to the control.
