In the multivariate survival analysis, when other risk factors (P < 0.05, HR > 1 in univariate analysis) such as clinical stage, tumor invasion, lymphatic invasion, distant metastasis, and QKI expression were taken into the multivariate mode, QKI expression, lymphatic invasion, and distant metastasis had predictive value for OS in patients with NSCLC (Figure 1G). The gene discussed is QKI; the disease is non-small cell lung carcinoma.
