Spearman’s correlation indicated that there was a significant correlation between serum CXCL-8 concentrations, depth of tumor invasion (T factor) (p = 0.010) and CRP concentrations (p = 0.003), while a positive correlation existed between SCC-Ag concentrations and TNM stage (p = 0.030) (Table 3). This evidence concerns the gene CXCL8 and neoplasm.
