CDH1 and gastric cancer: We also found that serum E-cadherin levels in the 22 patients with gastric cancer (3.51 +/- 1.78 micrograms ml-1, P < 0.02) or the 11 patients with hepatocellular cancer (5.55 +/- 3.11 micrograms ml-1, P < 0.001) were significantly higher than those in the 26 diabetic patients (2.33 +/- 1.58 micrograms ml-1).
