Assessment of diagnostic value of cytological examination in lung carcinoma in own material obtained by EBUS and EUS methods.


The aim of the study was the evaluation of the efficiency of cytological examination of the material obtained by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and endoscopic ultrasound bronchoscope-guided fine needle aspiration (EUSB-FNA) methods in the diagnosis of lung carcinoma. The usefulness was also assessed of the material obtained in that way for immunocytochemical and molecular tests in the diagnosis of non-small cell lung carcinoma. The material included cytological preparations obtained by EBUS and EUS methods. It was demonstrated that the technique made it possible to obtain diagnostic material from 94% of patients. A retrospective thorough analysis of those cases was the basis for the discussion of diagnostic difficulties.
