Comparison of EGFR mutation between MPE-cell blocks and matched MPTTs.

MPTT: metastatic pleural tumor tissue; MPE: malignant pleural effusion; +: EGFR positive-mutation; −: EGFR negative-mutation; *: among the 14 patients, one patient showed an exon 19 deletion in MPTT versus S768I mutation in the matched MPE-cell block.MPTT：转移性胸膜肿瘤组织（metastatic pleural tumor tissue）；MPE：恶性胸腔积液（malignant pleural effusion）； +：表皮生长因子受体（epidermal growth factor receptor，EGFR）突变阳性；−：EGFR突变阴性； *：在14例患者中，1例患者的MPTT标本检出19号外显子缺失突变，而其配对的MPE细胞块标本检出S768I突变。
