EGFR and squamous cell lung carcinoma: In a study of lung squamous cell carcinoma, Luo et al. used a bioinformatics tool to analyze the difference between lncRNA in 450 patients with primary lung squamous cell carcinoma and normal tissues, and showed that AC064853.2, AC090044.2, CTD‐3099C6.9, and KB‐1836B5.4 can be used as biomarkers for the diagnosis of lung squamous cell carcinoma.19 Wang et al. analyzed the difference between EGFR 19 exon mutation and EGFR wild‐type lncRNA in advanced NSCLC patients by lncRNA microarray and qRT‐PCR.
