Surgery for small cell lung cancer: A Surveillance, Epidemiology, and End Results (SEER) Survey from 2010 to 2015

This study explored whether surgery offered a survival benefits for patients with SCLC. Patients diagnosed with SCLC between 2010 and 2015 were selected from the Surveillance, Epidemiology, and End Results (SEER) database. The tumor, node, and metastasis (TNM) stage of SCLC in these patients was reclassified according to the 8th edition of the TNM classification for lung cancer. Overall survival (OS) was separately compared according to TNM stage between patients who underwent surgery and those who did not using Kaplan–Meier method. A Cox regression model was used to identify relevant variables affecting survival. Additional Kaplan–Meier curves were created to compare different types of surgery. Cox regression models and Forest plots were used to identify the predictors of survival in the surgery cohort. A total of 26,659 patients with SCLC were included, among which 627 (2.4%) patients underwent surgery. Surgery was associated with longer survival in patients with stage IA (45.0 vs 20.0 months, P
