Moreover, our Kaplan-Meier survival analysis showed that high mRNA levels of KLK5 and L1CAM are most significantly associated with poor clinical outcome of NSCLC patients (including LUAD and LUSC) in the TCGA cohort (Figures 2E, 3, Figures S3A–F). The gene discussed is L1CAM; the disease is non-small cell lung carcinoma.
