EGFR mutations in patients with lung adenocarcinoma and malignant pleural effusion: a propensity score-matched analysis of a single-center database

Malignant pleural effusion (MPE) is associated with poor prognosis in patients with advanced lung adenocarcinoma (LUAD), and abnormal activation of epidermal growth factor receptor (EGFR) plays a crucial role in the development of LUAD. This study aimed to investigate the correlation between
