This study aimed to assess the role of pleural fluid analysis in diagnosing pleural malignancy. Thoracentesis and closed needle biopsy of parietal pleura, using Cope's needle, were performed in 45 cases of pleural effusion coming to Department of Pulmonary Medicine. Samples were processed and studied as per standard methods. The male to female ratio was 4.6:1. Age range was 18-74 years. Two pleural effusions were transudates. Amongst the 43 exudates, 17 cases were malignant on pleural fluid analysis. Cyto­histological correlation was 68.4% for malignancy. Adenocarcinoma was the most common malignancy. Pleural fluid showed good sensitivity, specificity and accuracy. In developing countries, where investigations and health facilities are inadequate and cost of treatment is un-affordable, careful analysis of pleural fluid still remains a very convenient, low-cost and safe investigation that helps in diagnosing cases of malignant pleural effusion. Its combination with pleural closed needle biopsy can further enhance its usefulness in diagnosing pleural malignant lesions.
