Primary bronchogenic carcinoma: clinical profile of 279 cases from mid-west Rajasthan.

ABSTRACT

The present retrospective study was undertaken to study the clinical profile of primary bronchogenic carcinoma seen during last eight years in a teaching hospital. Out of a total of 279 diagnosed cases, 86% were males with an average age of 57 years, smoking was the risk factor in 81.6%. Forty percent of female patients were smoker with a significant overlap in use of smoking objects. Twenty four (8.8%) patients were less than 40 years of age at the time of diagnosis. Average duration of illness was 4.5 months. Weight loss (77%) and fever (34%) were the commonest general symptoms. Other chest symptoms include cough (68%), dyspnoea (59%), chest pain (22%), hemoptysis (20%) and dysphagia (6%). Fiberoptic bronchoscopy (FOB) (75%) and fine needle aspiration cytology (FNAC) (74.8%) were found to be the most efficient diagnostic procedures. Histologically, squamous cell carcinoma, adenocarcinoma, large cell carcinoma and small cell carcinoma were seen in 42%, 20%, 18% and 14% cases, respectively. Six percent patients showed malignant cells only and marked as unclassified. Radiologically, obstructive pneumonitis was the commonest presentation (59.5%) followed by mass lesion (31.8%) and rib destruction (5.1%). Inspite of its limitation, this study for the first time reports lung cancer pattern from mid-west Rajasthan.
