CR1 and esophageal squamous cell carcinoma: CR-1, N-cad, and Vim expression in ESCC cells were positively correlated with disease occurrence and clinical stage (r = 0.989, P < 0.05), while E-cad expression in ESCC cells was negatively correlated with disease occurrence and clinical stage (r = −0.905, P < 0.05) (Tables 1 and 2).
