Diagnostic accuracy of bronchoalveolar lavage fluid in diagnosis of lung cancers
Dr. Lokesh Haswani

Background:Globally, lung cancer is the most prevalent type of cancer. High incidence and a high case fatality rate are linked to it. The present study was assessed the diagnostic accuracy of Bronchoalveolar lavage fluid in diagnosis of lung cancers. Materials & Methods:BAL fluid obtained from 102 patients by lavage of respiratory tract in clinically and radiologically suspected lung lesions were selected. The results of the BAL were linked with the lung biopsy, and the biopsies were stained with Hematoxylin and Eosin. Results: Out of 102 samples, 60 were males and 42 were females.BAL fluid revealed SCC in 65, AC in 20, SmCC in 12, PDCC in 5 cases and severe dysplasia in 2 cases. Biopsy revealed SCC in 74, AC in 11, SmCC in 5, PDCC in 2 cases and severe dysplasia in 4 cases. The difference was significant (P< 0.05).BAL positive showed lung cancer in 35 cases and BAL negative in 30. The sensitivity was 63.7%, specificity in 82.4%, positive predictive value in 87.3% and negative predictive value in 61.5% cases. Conclusion: BAL fluid analysis offers a quick and accurate method for identifying and classifying lower respiratory tract cancers.
