Abstract :

Aim: Our aim is to determine the diagnostic accuracy of percutaneous fine needle aspiration cytology (FNAC) in various lung carcinoma cases with its histopathological correlation as gold standard.

Material and Method: We performed percutaneous FNAC in sixty patients which are presenting with respiratory symptoms and having localized lung lesions as confirmed radiologically.

Results: In our study, the M: F ratio of 5.67:1 in 78.9% of the lesions, we found primary epithelial lung malignancy, in FNAC finding. Among malignant lesions, twenty two cases were subjected and correlated with histopathological finding and diagnostic accuracy of FNAC is found to be 100% for small cell carcinoma, 87.5% for squamous cell, 83.3% for adenocarcinoma and 66.7% for poorly differentiated large cell carcinoma. The cytological yield of FNAC was 95.0%. Material in three cases was inadequate for interpretation. Adenocarcinoma was the commonest malignancy seen in females. Commonest malignancy seen among smokers was poorly differentiated large cell carcinoma followed by small cell and squamous cell carcinoma and the 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.
