Objective: Small cell lung cancer (SCLC) constitutes about 15-25 % of lung cancers with high mortality rate. Herein we observed the effect of parameters at the time of diagnosis to survival of cases with SCLC. Methods: We evaluated 65 patients who were followed up in our oncology department retrospectively. Results: Tumor location and stage at the time of diagnosis, smoking history, accompanying comorbidities, ECOG PS, laboratory parameters and treatments applied in pursuit were evaluated. 3-month survival rate of patients was 75.9%, 50.2% for 6-month, 21.4% for 1 year, and 5.5% for 2 years during follow up. ECOG PS and stage were found statistically significant risk factors in model created to determine overall survival. Conclusion: Performance score at the time of diagnosis, stage and presence of liver metastasis are identified as prognostic factors for SCLC and of these factors are quite valuable to predict the clinical outcome.
