GSE31210 including 246 NSCLC samples was selected for further analysis, and patients with lower mRNA levels of G6PD were significantly associated with longer OS and relapse-free survival (RFS) than those with higher expression (Fig. S6A, B), demonstrating the unique role of G6PD in SCLC. The gene discussed is G6PD; the disease is non-small cell lung carcinoma.
