Retrospective analysis characterizes lung cancer demographics and histopathology among smokers and non-smokers in eastern India, indicating significant differences in profiles.

Key Points

The aim is to analyze the demographic and clinic-pathological features of primary lung cancer in eastern India, focusing on smoking status.
Conducted a retrospective analysis of thoracic tumors treated at a hospital from June 2014 to May 2025.
Included patients with histologically proven lung cancer, collecting data from inpatient and outpatient records.
Analyzed 2,683 patients after excluding those with benign tumors or incomplete data.
1,883 males and 792 females, with a male-to-female ratio of 2.38 and an average age of presentation of 57.76 years.
46% of available histories indicated patients were non-smokers, with over 91% presenting with metastatic lung cancer.
Adenocarcinoma comprised 76.57% of diagnoses in non-small cell lung carcinomas, with notable mutation rates in EGFR and ALK.
