Research overview

In this study, serum samples were collected from lung adenocarcinoma patients with LC. And the combination of miRNA-1296-5p, miR-499a-5p and miR-370-3p with CEA can further enhance this potential.

Key findings

The results of miRNA sequencing revealed seven differentially enriched miRNAs (miRNA-1296-5p, miR-503-5p, miR-499a-5p, miR-374a-5p, miR-3173-5p, miR-370-3p and miR-885-3p).

0001), displaying higher diagnostic power for LC.

Study design

In this study, serum samples were collected from lung adenocarcinoma patients with LC.

The control groups consisted of patients with early-stage and advanced-stage lung adenocarcinoma without LC.

Serum exosomes were isolated for high - throughput RNA sequencing to screen for differential miRNAs, and the results were validated in 123 samples.
