Objective: To evaluate the characteristics, treatment received, survival, and prognostic factors of small cell lung cancer patients. Methods: A retrospective cohort study was conducted at the reference a public cancer-center in Rio de Janeiro, Brazil. A total of 866 small cell lung cancer patients admitted in the period 2000-2020 participated in the study. Comparison between survival curves was performed by the log-rank test; variables whose p < 0.10 entered in the Cox regression models expressed as hazard ratios (HR) with 95% confidence intervals. The association between receiving best supportive care (none treatment) and admission period was evaluated by means of logistic regression. Results: Median and 12-months survival were 6.2 and 23.7%, respectively. On multivariate Cox regression adjusted for treatment, poor (HR: 1.99; 1.57-2.51) and unknown performance status (HR: 2.79; 2.22-3.49), non-white skin color (HR: 1.25; 1.07-1.46), extensive (HR: 1.62; 1.29-2.04) and unknown staging (HR: 1.33; 1.07-1.65) remained associated with 12-months survival. Patients admitted during the last three admission period were nearly four times more likely to receive best supportive care in comparison to the first period. Conclusion: The prognosis of small cell lung cancer is poor and the perspective toward increasing their survival is to improve the timely access to diagnosis and treatment.
