Abstract. Diagnostic efficacy of endoscopic techniques, such as endoscopic autofluorescence imaging (AFI) and narrow-band imaging (NBI) was evaluated in 73 patients with primary central and multiple primary lung cancer. Inclusion of AFI and NBI endoscopic techniques in the diagnostic algorithm allowed us to increase diagnostic specificity and accuracy to 100% and to perform targeted biopsy with morphological verification in all patients included in the study. Videobronchoscopy enabled latent primary multiple malignant tumors in the contralateral lung to be revealed in 5.5% of cases.
Key words: videobronchoscopy, autofluorescence imaging (AFI), narrow-band imaging (NBI) diagnostic efficacy, primary and multiple primary lung cancer.
