Abstract
Abstract Background The absence of thyroid transcription factor 1 (TTF‐1) is associated with a lower frequency of epidermal growth factor receptor (EGFR) mutations in lung adenocarcinoma (LUAD). The aim of this study was to assess the impact of TTF‐1 expression on the clinical response to EGFR‐tyrosine kinase inhibitor (TKI) treatment in patients with advanced LUAD. Methods The data of patients with advanced LUAD who were admitted to the Beijing Tiantan Hospital and Peking University Cancer Hospital (China) between April 2009 and May 2023 was retrospectively analyzed. Results A total of 227 patients diagnosed with advanced LUAD were included, of which 28.2% (64/227) had TTF‐1‐negative adenocarcinoma, while 54.6% (124/227) harbored EGFR mutations. Negative TTF‐1 expression significantly correlated with male sex (68.8% vs. 42.3%, p
