Diagnosis of pulmonary malignant lesions by computed tomography guided FNAC & its histomorphological correlation

Introduction: Lung cancer is the most common amongst the malignancies in the world. In India the exact incidence of lung cancer is not known due to lack of formal epidemiological data across the country. However there is likely to be an estimated increase of 10% new cases/ year in next five year. Aims & objectives: To find out diagnostic accuracy of CT guided FNAC in lung cancer patients. The findings were further correlated with the histopathological examination. Materials & Methods: 56 patients clinically diagnosed to have lung mass were subjected to CT guided FNAC. After aspiration, slides were smeared and stained with PAP & MGG staining. Later on confirmation was done by histopathological findings. Results & Observation: In this retrospective observational hospital based study maximum patients were in the age group of 6th to 7th decade with M:F of 3.67:1. Histopathological correlation was available in 49 cases out of 56 cases. 47 cases were reported as malignant on FNAC hence diagnostic accuracy was 96%. Conclusion: FNAC of lung is simple, safe & highly yielding method for diagnosis of lung tumor & is an outdoor procedure with minimal complications.
