EGFR and non-small cell lung carcinoma: Genes commonly linked to NSCLC survival, including EGFR (P = 0.002; log2 fold change [log2FC] = 0.42), MET (P = 0.04; log2FC = 0.29), and ERBB2 (P = 0.02; log2FC = –0.23), were differentially expressed in Cluster 1, but the KRAS gene was not (P = 0.17; log2FC = 0.11).
