CXCL8 and neoplasm: These included twelve cytokines (IP-10/CXCL10, Eotaxin/CCL11, TNF-β, IL-6, IL-12p40, PDGF-AB/BB, MCP-3/CCL7, IL-2, VEGF, Fractalkine/CX3CL1, IL-4, and G-CSF) positively correlated with both tumor thickness and LBD, nine cytokines (PDGF-AA, sCD40L, IL-10, MDC/ADAM11, GRO/CXCL1, TGF-α, IL-8, IL-9, and IL-13) positively correlated with the tumor thickness, one cytokine (MCP-1/CCL2) positively correlated with the tumor LBD, and one cytokine (IL-3) negatively correlated with the tumor thickness (Table 2, Figures S3 and S4).
