In addition, multivariate analysis revealed that miR-107 and smoking status are important diagnostic predictors for EGFR-sensitive mutations and NSCLC patients with high miR-107 expression levels and no prior history of smoking are more likely to have EGFR exon 19 deletion or EGFR p.L858R mutations. The gene discussed is EGFR; the disease is non-small cell lung carcinoma.
