Background: Lung cancer is the most common cancer in men worldwide. The incidence
continues to rise in both males and females with wide geographical variability. Lung cancer has a
high fatality rate. Early detection of lung cancer has better treatment outcome as early lung cancers
can be operated. But the diagnosis of lung cancer is delayed due to many factors.
Aims and Objectives: The aim of this study was to analyze the current clinico-pathological profile
and epidemiological trends in lung cancer patients from a single tertiary care centre with emphasis on
given on gender association and delay in detection due to misdiagnosis as tuberculosis.
Materials and Methods: A retrospective analysis of the data of in-patients diagnosed as Primary lung
cancer in the department of pulmonary medicine at SDSTRC& Rajiv Gandhi institute of chest
diseases, Bengaluru, Karnataka from August 2015 to September 2017.
Results: Lung cancer study is still a disease predominant in old age males. Smoking is one of the
major causative factors. In Non smokers, females and young age group (<40yrs) adenocarcinoma was
commoner than squammous cell carcinoma.17 patients (16.5%) were mis-diagnosed as tuberculosis
before the definitive diagnosis was made.
Conclusion: Due to widespread prevalence of tuberculosis, lung cancer poses a diagnostic challenge.
A significant number of lung cancer patients in our country still continue to be misdiagnosed as
tuberculosis. Poor diagnostic resources and economic constraints along with low clinical suspicion
lead to delay in diagnosis of lung cancer resulting in poor prognosis and survival.
