In multivariate Cox analysis, we found that the pre-treatment LMP2 (P = 0.007, HR = 0.051,95% confidence interval [CI]: 0.006-0.442) and MPR (P = 0.003, HR = 8.709,95% CI: 2.115-35.856) were independent prognostic factors for NACI-NSCLC (Table 2). This evidence concerns the gene PSMB9 and non-small cell lung carcinoma.
