The CCR6 mRNA expression level in tumor tissue was lower in female patients compared to the male group (median RQ: 7.622 and 7.845, respectively), as well as in patients aged > 65 than in those aged ≤ 65 (median RQ: 12.954 and 10.634, respectively), but the differences were statistically insignificant (p > 0.05, Mann–Whitney U-test) (Table 3). This evidence concerns the gene CCR6 and neoplasm.
