A three serum miRNA panel as diagnostic biomarkers of radiotherapy-related metastasis in non-small cell lung cancer.

Serum microRNAs (miRNAs) have been implicated as noninvasive biomarkers for lung cancer diagnosis. However, there are no sensitive and specific biomarkers for the detection of radiotherapy-related non-small cell lung cancer (NSCLC) metastasis. The present study aimed to investigate the role of three serum miRNAs, namely miRNA (miR)-130a, miR-25 and miR-191*, in diagnosing NSCLC, and their biological functions in radiation-mediated development of metastatic properties in A549 cells.

The correlation between EGFR mutation status and the risk of brain metastasis in patients with lung adenocarcinoma.

To explore the correlation between epidermal growth factor receptor (EGFR) mutation status and the risk of brain metastasis (BM) in patients with lung adenocarcinoma, the clinical data of 100 patients with pathologically confirmed lung adenocarcinoma and known EGFR mutation status at exon 18, 19, 20, or 21 were analyzed retrospectively. The incidence of BM was similar between patients with wild-type EGFR and those with EGFR mutations (p = 0.48).
