MUC1 and esophageal squamous cell carcinoma: By analyzing the expression of CCR7 and MUC1 in 153 ESCC tissue samples, we found the co-expression of CCR7 and MUC1 in ESCC, and the two molecules were both correlated with lymph node metastasis and prognosis; furthermore, the patients who co-expressed CCR7 and MUC1 had the highest recurrence rate and the lowest survival rate compared with the rest of the groups.
