Detection of <i>EGFR</i> gene mutation status from pleural effusions and other body fluid specimens in patients with lung adenocarcinoma

Abstract

This study showed that compared with body fluid sediment tumor cells and plasma free DNA samples, body fluid supernatant free DNA has a higher detection rate and sensitivity of tumor-specific mutations. Free DNA obtained from body fluid supernatants could be used as high-quality specimens for gene mutation detection in patients with lung cancer. This could be applied in treatment decisions and patient management.
