Abstract :

Objective: The present study was conducted to evaluate the diagnostic efficacy of percutaneous fine needle aspiration cytology (FNAC) in various lung lesions, predominantly those suspicious of being malignant. Material and Method: Over a period of 20 months, percutaneous FNAC was performed in sixty patients presenting with respiratory symptoms with localized lung lesions clinically, which were confirmed radiologically. Results: Male preponderance was observed in this study with M: F ratio of 5.67:1. The most common lesion was Primary epithelial lung malignancy found in this study which constituted 78.9% of the lesions. Among malignant lesions, adenocarcinoma was the most common (44%) followed by squamous cell carcinoma (31.1%).The cytological yield of FNAC was 95.0%. Material in three cases was inadequate for interpretation. In females most common lung malignancy was adenocarcinoma. In Smokers commonest lung malignancy was poorly differentiated large cell carcinoma followed by small cell and squamous cell carcinoma while least common was adenocarcinoma. Sensitivity for diagnosing small cell and non-small carcinoma was 100% and 89.5% respectively. Specificity was 100% for each. Conclusion: Percutaneous transthoracic FNAC is a quite safe, simple and reliable procedure in the diagnosis of lung lesions with a high degree of accuracy, sensitivity and specificity. FNAC should be used frequently to shorten the diagnostic interval and prompt therapy for persistent lung lesions.
