The\n EGFR<\/jats:italic>\n results of the two types of samples were compared using the paired Chi-square test, and the mutation positive rates in\n EGFR<\/jats:italic>\n exons 18, 19, 20 and 21 were compared between the two types of specimens using the four-grid Chi-square test.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Among the 40 tissue samples and pleural effusion samples, 21 and 18 cases of\n EGFR<\/jats:italic>\n mutations were detected, respectively, and the mutation positive rates were 52.5% and 45%, respectively. The \u03ba value of the consistency test of the two specimens was 0.851. There were no significant differences in the mutation positive rates in\n EGFR<\/jats:italic>\n exons 18, 19, 20, and 21 between the two types of specimens.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n \n The\n EGFR<\/jats:italic>\n results of pleural fluid and tissue samples were in good agreement. Therefore, we can use pleural fluid samples to detect\n EGFR<\/jats:italic>\n mutations to guide tyrosine kinase inhibitor treatment for NSCLC patients in whom tumor tissue samples cannot be
