e17505 Background: Lung cancer ranks among the most common and lethal malignancies worldwide and also in India. There are geographic and ethnic variations in incidences, clinical and pathological profile of lung cancer. There is paucity of data of changing trend of pathological and clinical profile from this part of the world. Methods: A total of 434 patients with lung cancer were analyzed who were registered at All India Institute of Medical Sciences, over a 3 year period, from July 2008 till June2011, based on information in hospital records. Survival analysis was performed on 310 patients who have received at least one modality of treatment. Results: Median age of the whole cohort was 55 years (23-84 years). There were 357 (82.26%) males and 77 (17.74%) females, 295(69.91%) smokers and 127 (30.09%) non smokers. 370 (85.25%) patients had NSCLC and 64 (14.74%) had SCLC. Among NSCLC, adenocarcinoma was the commonest histology (45.41%) followed by squamous cell carcinoma (29.46%) and unclassified NSCLC (20.54%). Majority (66.13%) of the diagnosis were based on biopsy (needle or bronchoscopic). Among NSCLC, 26.3% patients were of stage 1-3A and 73.7% were of stage 3B and 4. Among SCLC 25% patients were of limited stage and 75% patients were of extensive stage. 73.18% of NSCLC patients received chemotherapy, 19.15% received TKI and 5.75% received RT as first line treatment modality. Among SCLC 93.88% received chemotherapy and 6.12% received RT as first line treatment. Median PFS and OS of patients with NSCLC were 7.8 months and 13.2 months respectively while that of SCLC were 6.1 months and 9.2 months respectively. Conclusions: Pathological profile of lung cancer has changed in India. Adenocarcinoma has become the commonest histology, contrary to the older reports when squamous cell carcinoma was more common. Majority of the patients are diagnosed in advanced stage and survival of these patients remains poor.
