Objective: To analyze data of cases with lung cancer (LC) diagnosed in our clinic over one year period and compare them with data of cases with LC diagnosed before ten years. Method: The demographic data, radiological and bronchoscopic findings, diagnostic methods, and histological type and stages of the patients diagnosed with lung cancer in year 2005 were evaluated. Results: Over one year period, 138 patients were diagnosed with LC. 104 (75.4%) were men and 34 (24.6%) were women. Mean age was 63.78±9.53 (38-83). 118 (86.5%) of the patients had 39±16.34 (5-90) pack-years smoking history. Squamous cell carcinoma (SCC) was diagnosed in 40.6% of patients, adenocarcinoma in 29.0%, small cell carcinoma in 21.0%, conbined type in 8.0% and carcinoma with unidentified cell type in 1.4%. Squamous cell carcinoma was more common among smoking patients. It was determined that the distribution of histological types in this study was similar to the previous studies, however the incidence of LC was found as increased in females in our study when compared to previous studies. Conclusion: We conclude that SCC is the most common histological type in patients with LC in our clinic and the male to female ratio for LC is decreasing.
