Abstract
Abstract This study was conducted to explore whether polymorphisms of glucose transporter 3 (GLUT3) gene affect the prognosis of patients with non-small cell lung cancer (NSCLC) after surgical resection. Four single nucleotide polymorphisms (SNPs) in GLUT3 were investigated in a total of 782 patients with NSCLC who underwent curative surgery. The association of the SNPs with overall survival (OS) and disease free survival (DFS) was analyzed. Among the four SNPs investigated, GLUT3 rs7309332C>T was significantly associated with OS and DFS in multivariate analyses. The SNP was associated with significantly worse OS (adjusted hazard ratio [aHR] = 1.62, 95% confidence interval [CI] = 1.04-2.53, P = 0.03, under recessive model), and worse DFS (aHR = 1.64, 95% CI = 1.18-2.29, P = 0.003, under recessive model). When stratified by tumor histology, the association between the GLUT3 rs7309332C>T and OS/DFS was not limited to either squamous cell carcinoma (SCC) or adenocarcinoma (AC), although the significant association remained only in AC for OS (P = 0.40 for SCC and P = 0.04 for OS) and only in SCC for DFS (P = 0.03 for SCC and P = 0.08 for OS). When AC patients were stratified according to EGFR mutation status, the SNP was significantly associated with DFS in patients with EGFR mutant tumors (aHR = 2.47, 95% CI = 1.15-5.30, P = 0.02, under recessive model), but not in those with EGFR wild-type tumors. This study suggests that genetic variation in GLUT3 may be useful in predicting survival of patients with early stage NSCLC.
