A Combined test using both cell sediment and supernatant cell ‐free DNA in pleural effusion shows increased sensitivity in detecting activating EGFR mutation in lung cancer patients

ConclusionsA combined test using both cell sediment DNA and supernatant ccfDNA samples increases the concordance rate of EGFR mutations between primary tumour and corresponding metastases. Our findings indicate that supernatant ccfDNA is useful even in cases where the cytological diagnosis is negative.
