CDH1 and neoplasm: The levels of membranous E-cadherin were lower in tumor samples from patients with LNM [median (range) 3.54 (0.96–7.91) vs. 4.47 (1.19–21.05), P = 0.002]; while the levels of cytoplasmic vimentin and membranous EGFR were higher in samples from patients with LNM than from those without LNM [median (range) 13.51 (6.19–34.96) vs. 10.35 (4.5–21.99), P < 0.001; 13.74 (5.17–35.32) vs. 7.28 3.88–19.22), P < 0.001, respectively] (Table 1).
