ABSTRACT : Introduction : Transbronchial needle aspiration (TBNA) is a beneficial, safe and minimally invasive bronchoscopic technique used in the diagnosis and staging of bronchogenic carcinoma. Patients and methods: The study was conducted on 20 patients with clinical and/or radiological suspicion of bronchogenic carcinoma.They were admitted to Chest Department, Benha University Hospital. Fiberoptic bronchoscopy for inspection of the tracheobronchial tree and biopsy using TBNA and/or other sampling methods such as bronchial washings and forceps biopsy. Histopathological and cytological examination. results: The diagnostic yield of bronchial wash was (30%).The diagnostic yield of forceps biopsy was (45%).The diagnostic yield of TBNA was (85%). Addition of TBNA to the conventional diagnostic methods increased the diagnostic yield from (85%) to (90%). CONCLUSION: The diagnostic yield increased from 45% to 90% after addition of TBNA to conventional diagnostic techniques (Bronchial washing, Forceps biopsy)).Forceps biopsy is the best method for diagnosis of cases with exophytic mass lesions.TBNA is the best modality for diagnosis of cases with submucosal and Peribronchial lesions. • TBNA is a valuable tool in giving both diagnostic and staging information in patients with lung cancer. . • Application of TBNA decreases the need for other invasive investigations to sample the mediastinal lymph nodes.
