Comparison of the EGFR genotyping between cell block or cytology, cell-free DNA and EV-derived DNA from the supernatant of pleural effusions in EGFR-TKI acquired-resistance patients. a Detection of the T790 M mutation using cell block or cytology, cfDNA and EV-derived DNA of pleural effusions. The detection rate of the T790 M mutation is 17, 61, 72% in cell block or cytology, cfDNA, and EV-derived DNA of pleural effusions, respectively. b EGFR genotyping in accordance with tissue using a cell block or cytology, cfDNA and EV-derived DNA of pleural effusion are 39, 94, and 100%, respectively. cfDNA = cell-free DNA; EV-derived DNA = extracellular vesicle-derived DNA
