Role of computed tomography guided transthoracic aspiration in diagnosing bronchogenic carcinoma

Abstract

Introduction:

Bronchogenic carcinoma is the second most commonest cancer in both men & women next to colon carcinoma and breast carcinoma respectively. Though first noted in USA and European countries, now turned into world wide epidemic with increasing use of tobacco.

Objectives:

1. To study the computed tomography findings in bronchogenic carcinoma


2. To assess the role of CT guided FNAC in diagnosing bronchogenic carcinoma

Materials & methods:

This descriptive study included 100 consecutive patient suspicious of bronchogenic carcinoma admitted through outpatient block in the department of pulmonary medicine during the period of June 2021 to December 2021. They are subjected to computed tomography, fine needle aspiration and sent for histopathological examination and the findings are correlated.

Results:

60-70 years age group is commonly affected with bronchogenic carcinoma. Commonest aetiological factor is smoking. Mass lesion is commonest computed tomography finding. Right sided lesion are more common than left. Most of the lesions are presented with irregular margins. CT guided FNAC was done in all cases but yield was obtained in 65% of cases. Adenocarcinoma is commonest histopathological finding.

Conclusion:

Computed tomography which is the best noninvasive investigation that clearly defines the size,contour,extent of bronchogenic carcinoma and also helps in staging the bronchogenic carcinoma. CT guided fine needle aspiration cytology is simple and safe technique in diagnosing bronchogenic carcinoma.
