In order to explore the role of key genes and tumor immune cells played during prognosis of NSCLC, we selected one of GIrLncSigs AC027288.1 and one of immune checkpoints PD1 (PDCD1) for example to performed correlation analysis between gene expression and GIrLncSig risk score in TCGA NSCLC samples. This evidence concerns the gene PDCD1 and non-small cell lung carcinoma.
