Background: Lung cancer is the most common type of cancer in males and the leading cause of death in both sexes. It accounts for 11.3% of all new cancers in India and also associated with a mortality rate of 13.7%. This desolate mortality necessitates for the early diagnosis of lung cancer. The study was conducted to evaluate incidence, gender and age wise distribution of lung cancer and its association with smoking.
Methodology: This study was done in the department of pulmonary medicine in Guntur Medical College from September 2016 to august 2017. The study includes 52 patients having clinical and radiological suspicion of lung cancer. All the cases were subjected to USG guided transthoracic needle aspiration was sent for cytology. Inconclusive and malignant cases were further subjected to histopathological examination for confirmation.
Results: Out of the 52 patients suspicious of malignancy, 32 patients were finally diagnosed as malignant, 5 patients had benign/inflammatory lesions, 6 cases had no evidence of malignancy/non-specific inflammation, 8 had no opinion possible. Most common type is adenocarcinoma followed by squamous cell carcinoma with an incidence rate of 71.8% & 15.7% respectively. The highest incidence of lung malignancies is seen in 5th decade in both sexes.
Conclusions: There is increase in the incidence of lung malignancies in females, throwing light on the causes other than smoking like bio-mass fuel exposure and second-hand smoking. Adenocarcinoma is the most common type. Further, USG guided transthoracic needle aspiration has a good sensitivity in detecting lung malignancies.
