In post-treatment, the expression IL-8 (Figure 7b) in PC group is significantly higher than OX, NIS, OX + NIS, BC groups (t = 6.678, p < 0.001; t = 6.057, p < 0.001; t = 5.136, p < 0.001; t = 5.512, p < 0.001); the expression of IFN-γ (Figure 7c) in NIS group was significantly lower than in OX, OX + NIS and BC group (t = 4.435, p < 0.01; t = 4.776, p < 0.01; t = 5.663, p < 0.001), there was no statistical difference between OX + NIS group and BC group (p > 0.05). Here, CXCL8 is linked to breast cancer.
