Aims : To retrospectively evaluate the demographic, epidemiological, and clinical characteristics of patients diagnosed with lung cancer. Methods : Patients diagnosed and treated for lung cancer in our medical oncology clinic were included in the study. Patient records were obtained retrospectively from the electronic databases of the hospital. Demographic and clinical characteristics were recorded for each patient. Results : A total of 313 patients diagnosed with lung cancer were included in the study. Mean age was 62.7+/-10.3 years. Of the patients, 83.4% were male and 16.6% were female. Most common presenting complaints were dyspnea (40.9%) and chest pain (32.2%). Smoking history was present in 66.5% of patients, and 15.3% had a history of tandoori smoke exposure. Radiologically, the most frequent tumor localization was the right upper lobe (38%). Most common histopathological types were squamous cell carcinoma (39.3%), adenocarcinoma (27.2%), and small cell carcinoma (20.1%). Most common disease stage at the time of diagnosis was stage IV (48.9%), followed by stage III (39%), II (10.9%), and I (1.3%). Mean OS was 14+/-1.4 (range, 11.2-16.8) months. Higher ECOG performance scores and advanced stage were associated with poorer survival. Mean OS was 31 months for females and 13 months for males. Conclusion : The findings obtained in our study were found to be consistent with those of previous research. In Turkiye, the high prevalence of smoking, the asymptomatic nature of the disease, and the tendency of patients to attribute existing symptoms to smoking appear to contribute to delayed presentation to healthcare facilities, which likely plays a role in the high proportion of advanced-stage diagnoses. Additionally, unlike in other studies, the higher proportion of female patients diagnosed in our cohort was considered to be related to the widespread use of tandoori ovens in our region.
