Moreover, the overexpression of miR-222 and miR-155 was associated with poor prognoses, positive EGFR mutation, and metastasis in late-stage NSCLC, and that overexpression of miR-34 represents a biomarker for LADC cell type, multiple metastases, and LADC negative EGFR mutation [184]. Here, EGFR is linked to non-small cell lung carcinoma.
