Abstract
SUMMARY: Recently, Glut1 (human erythrocyte glucose transporter) expression has been demonstrated in various tumors. The aim of this study is to evaluate the prognostic utility of Glut1 expression in esophageal carcinomas. We studied Glut1 expression by immunohistochemistry of paraffin sections from 63 esophageal squamous cell carcinomas. All 63 carcinomas expressed Glut1. The mean percentage of positively stained tumor cells was 77.8% (median, 84.7%). There were two staining patterns in positive cells: 'strongly positive' and 'weakly positive'. The percentage of 'strongly positive' cells (%Glut1-SP) ranged from 0% to 95.6% (mean, 32.3%; median, 27.4%). The 5-year survival rate for patients with a high %Glut1-SP (> 30%) was significantly lower than that for patients with a low %Glut1-SP (< 30%) (P < 0.01). Statistical analysis revealed that the relative risk of death for patients with high %Glut1-SP was 2.02 times that for patients with low %Glut1-SP (P = 0.064), suggesting a possible independent predictive value for %Glut1-SP.Entities:
