A similarly high CCR7 mRNA level in esophageal cancer cells from tissues correlating with lymph node metastasis was observed, although, overall, CCR7 mRNA levels in primary esophageal tumor cells did not show such a correlation, likely due to the presence of CCR7-positive infiltrating lymphocytes within the lymph nodes [125]. Here, CCR7 is linked to neoplasm of esophagus.
