Values of napsin A and CEA in ELF in the patients with primary lung adenocarcinoma. a Levels of napsin A in ELF (ELF-napsin A) in the patients with primary lung adenocarcinoma (n = 29, P < 0.001). b Values of CEA in ELF (ELF-CEA) in the patients with primary lung adenocarcinoma (n = 29, P = 0.634). c ELF-napsin A in the patients with primary lung adenocarcinoma who were undiagnosed by bronchoscopy and finally diagnosed by surgery (n = 18, P = 0.001). d ELF-CEA in the patients with primary lung adenocarcinoma who were undiagnosed by bronchoscopy and finally diagnosed by surgery (n = 18, P = 0.571). CEA: carcinoembryonic antigen; ELF: epithelial lining fluid
