Of all the cases investigated for suspected lung cancer between June 1999 and June 2003, 196 cases were selected where flexible bronchoscopic samples of broncho-alveolar lavage (BAL) and bronchial brush (BB) cytology as well as bronchial biopsy were taken and processed as per standard procedures of cytology and histology. The aim of this study was to compare the diagnostic efficacy of BAL and BB cytology in diagnosing lung cancer, taking bronchial biopsy as the 'Gold Standard' diagnostic test. Sensitivity of BB was 87.3%; while that of BAL was 39.4%. Specificity of BB and BAL was 97.6% and 89.6%, respectively. BB was better than BAL in morphological typing of lung cancers. We conclude that bronchial brushing is a much superior technique in the diagnosis and morphological typing of lung cancers.
