In multivariate logistic regression analysis, NSCLC patients with GLK-High had high risks of cancer recurrence (n = 58, OR = 9.98, 95% CI, 2.24–44.5, P = 0.003) after adjusting for the pathologic stage, smoking status, alcohol status, and EGFR protein levels (Table 2). This evidence concerns the gene EGFR and cancer.
