Low-dose computed tomography can identify smaller nodules more often than chest radiography in lung screening. However, complications from invasive diagnostic procedures performed to detect nodules are common. Exosomes contain a diverse array of biomolecules that reflect the biological state of the cell from which they are released. The aim of this study was to investigate the diagnostic value of bronchoalveolar lavage (BAL) fluid exosomal microRNAs (miRNAs) for early-stage lung adenocarcinoma. ⋯ We identified a close correlation between BAL fluid exosomal miRNAs and tumor miRNAs. BAL fluid exosomal miRNAs obtained through noninvasive methods could serve as diagnostic biomarkers in early-stage lung adenocarcinoma.

Although patients with EGFR-mutant non-small-cell lung cancer (NSCLC) benefit from treatment with EGFR-tyrosine kinase inhibitors (TKIs), outcomes are limited by the eventual development of acquired resistance. We conducted a retrospective study to evaluate the efficacy and feasibility of EGFR-TKI therapy beyond focal progression, associated with microwave ablation. ⋯ The longer disease control observed in our patients suggests that continuation of EGFR-TKI beyond focal progression associated to microwave ablation is an efficacious therapeutic strategy.
