To further investigate the dysregulated circulating plasma microRNAs in NSCLC EGFR mutation-positive (EGFR exon 19 deletion or EGFR p.L858R mutation) patients, we performed qRT-PCR with 5SrRNA as the endogenous control for the EGFR exon 19 deletion, EGFR p.L858R mutation, and EGFR wild-type groups. This evidence concerns the gene EGFR and non-small cell lung carcinoma.
