CCL20 and neoplasm: The expression level of CCL20 was higher in tumor tissue of AC patients than control tissue (median RQ: 2.399 and 0.411, respectively), as well as in tumor tissue of SCC patients compared to control (median RQ: 0.287 and 0.174, respectively); however, the differences were statistically insignificant (p > 0.05, Mann–Whitney U-test).
