A study of radiological presentation in bronchogenic carcinoma along with prevelance of pulmonary TB in a tertiary center

Background Lung cancer is most common cause of cancer related death in men and women world wise responsible for over 1 million death annually. Lung cancer is leading cause of cancer death in united states and worldwide. Lung cancer is the most common neoplasm contributing more frequent among males causing cancer related mortality in both sexes. Objective of this study was to radiological presentation in bronchogenic carcinoma along with   prevalence of pulmonary TB in a tertiary center.

Methods Total of 100 patients with histologically proven lung cancer, from July 2018 to June 2019 at a tertiary center Kota Rajasthan. Data of participants regarding demographics, history of smoking habit, clinical presentation, histopathological type, radiographic findings on chest radiograph, ultrasonography, computed tomography (CT) scan, Statistical analysis was performed using descriptive statistics of the collected data.

Results Most common age group of bronchogenic carcinomas was seen between 60-69 years of age (37%) with male predominance (82%).  smoking history present in about (80%) patients.  Most common radiological presentation was a mass lesion present in 91% patients (n=91) followed by unilateral hilar prominence present in 44% of patients (n=44). Other common finding includes mediastinal widening (38%), collapse (26%). pleural effusion (22%), metastasis (22%), cavitation (13%), consolidation (12%), bony erosion (11%), pneumothorax (5%), and pancost tumor (4%).  prevalence of pulmonary TB in bronchogenic carcinoma is 9% and this is due to high burden of pulmonary TB in India.

Conclusions In this study adenocarcinoma was found to be most common type of lung cancer. Smoking is most common risk factor. Pulmonary TB coexistence with bronchogenic carcinoma was more common. The local immunity is deteriorated in cancer cases.
